Executive Summary

Overview: Pima County Regional Flood Control District (District) has evaluated the historical and current water balance and effects on regional groundwater conditions, and potential impacts on the hydro- and meso-riparian vegetation along the watercourses of the Cienega Creek Watershed (CCW) . The CCW study area is approximately 475 square miles in eastern Pima County, western Cochise County and northeastern Santa Cruz County, Arizona, with most of the basin in Pima County (Figure 1-1, Area Map). The amount of the CCW in the Arizona Department of Water Resources (ADWR) Tucson Active Management Area is 80 square miles, mostly within the southern portion of Davidson Canyon (Figure 1-1) Pima County (County) property within the CCW includes the Cienega Creek Natural Preserve (CCNP) in the lower part of the watershed, Bar V Ranch, Empirita Ranch, and Sands Ranch and Clyne Ranch. Cienega Creek stream flow supports rare and endangered fish and frogs as well as dense areas of riparian vegetation including cottonwoods, mesquites, and willow that provide shelter and foraging habitat for a wide variety of birds, bats, and other wildlife species. These unique natural resources are under threat from man-made land use changes and natural changes, including global climate change. The County and the US Government have invested millions to protect the CCNP in the lower watershed and the Las Cienegas National Conservation Area in the upper watershed and other important conservation areas in the CCW. The County has begun to compile risk assessments of potential threats, including drought, depletion of groundwater, land use and mining, and develop appropriate management strategies to reduce or eliminate impacts from these threats to the sustainability of the Cienega Creek Watershed.

Geologic Features : Sedimentary units underlying the area, consist of the Quaternary surficial deposits, Tertiary older basin fill alluvium, Pantano formation and hydrologic bedrock. Differences between the upper and lower basins have to do with the thickness of the formations. The younger alluvium is thin in both basins, not exceeding about 200 feet in the upper basin and may not reach 100 feet in the lower basin. Although productive with significant sands and gravels, the recent alluvium does not provide an appreciable amount of water for large well use. However, it provides an abundant amount of water for riparian trees and vegetation along Cienega Creek, its tributaries and Davidson Canyon. The basin fill can be as thick as 1,200 feet south of I-10 near Empirita Ranch, but productivity of the aquifer diminishes with depth. In the upper basin, the basin fill consists and lenses of sands, gravels and silts and is as deep as 2000 feet near Sonoita, and more productive in the Empire Ranch area along the Cienega Creek corridor and floodplain. In some areas the basin fill of the upper basin could be semi–artesian potentially due to the sequences of silts and clays. The Pantano formation, consisting of mostly consolidated and cemented sandstone, unproductive claystone and mudstone, present in the lower basin, and in some areas such as downstream of Pantano Dam, forms a semi-impermeable layer above the recent alluvium. In areas of the upper basin the Pantano formation may underlie the basin fill in the deeper portions of the aquifer near Sonoita. Bedrock consists of consolidated sedimentary rocks with a mix of plutonic, igneous and other sedimentary rocks. The underlying bedrock complex and the surrounding mountains yield little water to the system but serve as a primary recharge medium for the mountain fronts in areas of large and smaller fractures and can provide movement of water toward the central portions of the basins. Where the bedrock nears the surface along Cienega Creek and Davidson Creek, groundwater is forced to the surface due to the very low permeability of the bedrock. The “Narrows”, Pantano Dam and “Three Bridges” have shallow bedrock underlying Cienega Creek bed and adjacent confining bedrock along the sides of the Creek.

Groundwater Conditions: Of the over 2000 wells in the upper and lower Cienega Basin, most are private domestic wells. Well pumping is focused in three main areas: Sonoita, Vail and the Jay-6 area near I-10 and the Cochise/Pima County line. The other area is spread among private wells within the upper and lower basins. Pumping has increased from about 2,290 acre- foot (AF) in 1984 to almost 4,700 AF by 2014. The dominant pumping categories in 2014 include private domestic, at 1,700 AF, 1,850 AF for municipal wells, 885 AF for agriculture and 265 AF for industrial/mining.

Groundwater movement generally mimics surface topography, following the path of Cienega Creek in the lowlands and moving north-northwesterly toward the Tucson Basin. The most recent water-level data compiled in 2014-2015 show varying depth to groundwater, ranging from below 50 feet near the channel corridor of Cienega Creek north of I-10 and south of the “Narrows” and in some areas of Davidson Canyon; near 100 feet north of I-10 and on the Empirita Ranch; near 200 feet in the Sonoita area; 200-300 in the Jay Six area near I-10 and the Cochise/Pima County Line; and 300-500 feet in the Vail area near Colossal Cave Road. Some of the areas recognized as designated Shallow Groundwater Areas are now deeper than 50 feet, especially south of I-10 on Empirita Ranch.

Historic water levels show a declining trend since the early 1980s, especially in the lower Cienega Basin. Deeper wells show steeper declines over the last 20-30 years. Shallower wells near perennial reaches show less decline, but there is still a declining trend. Overall, the lower Basin shows a water level decline of about 0.9-0.95 feet/year (ft/yr) over the last 20-30 years. The decline in the last 10-years in the lower Basin has been about 0.5 ft/yr. The probable stressors are drought and increased pumping in the Vail, J-6 areas and more private domestic wells in the area. The upper Basin appears more resilient to water-level decline and experienced less increased pumping than the lower Basin. The declines in the last 20-30 years range from 0.2-0.3 ft/yr. However, water-level declines in the last 10 years have increased to 0.6 ft/yr, possibly due to increased pumping and drought.

Despite significant flood flow and volumes recorded at Pantano Dam in the last 10 years, lack of significant winter flows have minimized recharge of the upper and lower basins and recoveries of shallow groundwater levels in the area. The declining groundwater levels have also resulted in reduced perennial flow and flow length since 1994.

Several local and watershed-wide groundwater modeling studies have been performed over the last 35 years. University of Arizona models developed in the 1980s-1990s projected significant water-level declines could result from high volume pumping in the upper and lower Basins from proposed mining or residential development and suggested levels that could threaten the riparian habitat along the Cienega Creek. In the past 10 years conceptual and three-dimensional flow models have been developed covering the mid-upper and portions of the lower Basin, evaluating the impacts of the proposed Rosemont mining pit, on the water surface elevation of these areas. The major models looked at the specific declines resulting from the Rosemont pit redirecting groundwater and changing gradients for the final Rosemont Environmental Impact Statement. The models showed significant declines would result from pit excavation, even with the importation of water pumped from the Upper Santa Cruz Basin to process. The geographic extent of mine impacts on water levels would increase over time, projecting from 50 to 100 to 1000 years in the future. The models did not account for the current pumping impacts or a range of climatic conditions. These models did not account for the current declining water level conditions in the

Basin. As such, these models were not adequate in projecting the overall impacts of current and future pumping, and a range of climatic conditions coupled with mine pit construction.

Water Quality and Geochemistry: Groundwater and surface water quality in the Cienega Basin is influenced partially by geology, including gypsiferous bedding in lower Cienega, lower total dissolved solids (TDS) in the Davidson Canyon area and upper Cienega Creek, and different water types. The lower Cienega basin is dominated by calcium-sulfate–bicarbonate waters, except for groundwater at Pantano Dam which is sodium sulfate and dominated by older recharge. Davidson Canyon and the upper watershed groundwater and surface water are dominated by lower TDS, calcium-bicarbonate types and sodium bicarbonate types.

Isotopic compositions of water samples can provide a useful tool for investigating hydrological processes in surface water and groundwater systems. Isotopic results, mostly limited to Davidson Canyon and lower Cienega Creek show groundwater wells, springs, and surface water samples having oxygen and hydrogen indicate a mix of summer and winter precipitation contributions, with a dominance of winter recharge and some evidence of evaporation prior to recharge or flow. Davidson Canyon Wash surface water flows generally reflect a winter groundwater source, compared to sites closer to the confluence of Cienega Creek. Some wells in the proposed Rosemont project area, a spring about 2-miles west of the proposed mine site, and a site over 10 miles downstream in Davison Canyon Wash may have less interaction with modern precipitation compared to most other sampled sites. Tritium concentrations in wells and springs provide an apparent age of groundwater, and results indicate that most groundwater was likely recharged from a mix of modern recharge (<10 years old) and older pre-bomb pulse recharge (>~60 years old).

Alternative Supplies: There are no alternative water supplies to support future development outside the Vail Water Company service area. Groundwater is the sole supply for existing and future land uses outside the Vail area.

Recommendations: Based on the findings from this evaluation, the following recommendations have been developed for further consideration:

• An upper and lower Cienega Creek three dimensional computer model is needed to predict land use impacts on groundwater for these areas. • Acquire adjacent and nearby properties and water rights where possible to minimize pumping adjacent and near the CCNP. Collaboration with such entities as the Arizona Land and Water Trust is also important to find ways of land acquisition and easements. • Update land management plans. The Cienega Creek Management Plan and all Ranch Plans within Cienega Creek Watershed need updating every five to ten years because of urban encroachment, more mining claims and drought conditions. Plans need to conform with the County’s forthcoming Endangered Species Act Section 10 permit. Additional strategies to protect shallow groundwater and in-stream flow need incorporation in the updated Plans. • Restore surface water flows diverted from the inholding at Pantano Dam. Stream base flow is being diverted to Del Lago Golf course and diversion of the water back across the dam to recharge the shallow aquifer will bring water levels up providing more riparian habitat. If required by U. S. Fish and Wildlife Service’s forthcoming Final Biological Opinion, Rosemont may purchase and release some portion of the diverted flows to the streambed in order to offset impact to endangered fish. If the water rights remain with Del Lago Golf

Cienega Creek Groundwater Evaluation Page iv

course, then the long-term solution could be County acquisition through bonds or other sources. • Pursue methods to enhance upland recharge of stormwater to stabilize water levels. Non-structural methods mimicking the site hydrology including preserving any natural areas, using small scale berms and check dams in first order tributary channels. • A public awareness program is needed to educate citizens of the important connection between water and riparian areas and promote more water conservation throughout the Basin. Focus is needed on exempt private well owners and non- exempt municipal providers. • Seek state authorization to treat all non-exempt well owners in the Cienega watershed similarly. At present, well owners in the Tucson Active Management Area must report pumping and pay a pump tax. No basis exists for excluding well owners from the same provisions. • Continue and expand precipitation, stream flow, spring, and groundwater sample collection, especially in higher elevations, and analyses for stable (δ18O, δD) and radioactive isotopes (tritium), plus major ion chemistry (anions, cations, and alkalinity). Insure funding is available to continue the monitoring effort. • Continue groundwater level and nearby stream (length and flow) and precipitation monitoring in in the upper and lower Basins. Evaluate areas where data is lacking such as between the Narrows and I-10. Insure funding is available to continue the monitoring effort. • The State should implement Special Basin Status for this unique area, restricting and offsetting water use with another supply or strict water conservation. Because Cienega Watershed is protected by the State as Outstanding Waters, by Pima County with the CCNP and by the US for LCNCA, ADWR needs to afford the Basin special protection, evaluating discretionary water uses to minimize impacts from additional water withdrawals in the basin.

Cienega Creek Watershed Groundwater Evaluation

1.0 Introduction and Background

The Cienega Creek Watershed is an approximately 475 square mile basin in eastern Pima County, western Cochise County and northeastern Santa Cruz County, Arizona. Most of the watershed lies in Pima County (Figure 1). The total amount of the Cienega Creek watershed in the Arizona Department of Water Resources (ADWR) Tucson Active Management Area is 80 square miles, mostly within the southern portion of Davidson Canyon (Figure 1). Pima County owned property within the Cienega Creek Watershed includes the Cienega Creek Natural Preserve (Preserve) in the lower part of the watershed, Bar V Ranch, Empirita Ranch, and Sands Ranch and Clyne Ranch. Pima County established the CCNP in 1986 to protect Cienega Creek, one of the few low-elevation perennial streams in Pima County. Cienega Creek stream flow supports rare and endangered fish and frogs as well as dense areas of riparian vegetation including cottonwoods, mesquites, and willow that provide shelter and foraging habitat for a wide variety of birds, bats, and other wildlife species. These unique natural resources are under threat from man-made land use changes and natural changes, including global climate change. The County has invested over $64 million to protect the Preserve and other important conservation areas in the Cienega Creek Watershed. At this time the County has begun to compile risk assessments of potential threats including drought, depletion of groundwater, land use and mining, and develop appropriate management strategies to reduce or eliminate impacts from these threats to the sustainability of the Cienega Creek Natural Preserve.

The County ranches were purchased by Pima County as an effort in the Sonoran Desert Conservation Plan (SDCP) to protect and preserve vast areas of natural open space and preserve the heritage and culture of the Southwest. They also typically, from a groundwater depletion view, use less amounts of water than other land uses such as housing developments, irrigated agriculture and mining.

A large portion of the upper Cienega Creek Watershed is public land occupied by the 42,000 acre Las Cienegas National Conservation Area (LCNCA), managed by the U.S. Bureau of Land Management, and the Santa Rita Mountain Coronado National Forest, managed by the U.S. Forest Service (Figure 1). The LCNCA has a conservation plan that indirectly limits use of groundwater that may reduce the perennial flow of Cienega Creek and tributaries or harm riparian areas and aquatic habitat (Public Law

106-538, Sec 4a). Certain water intensive activities such as mineral and gas extraction are prohibited. However, The Coronado National Forest and Santa Rita Mountain area has to consider mining leases and their use related to the impacts to the environment, including diminishment of the groundwater table and water resources. Mine proposals from mining claims in the Forest are a constant issue regarding land use and stressors for the Cienega Creek Watershed. In particular, the proposed Rosemont Mine in the western portion of the upper watershed is being evaluated in an Environmental Impact Statement and the impacts to the groundwater and water may have far reaching effects over the entire Cienega Creek Watershed (U.S. Forest Service, 2013).

The small town of Sonoita lies at the upper portion of the Cienega watershed and basin with rural ranchettes and individual wells in the vicinity. The community of Vail lies at the downstream end of the watershed and urban encroachment with accompanying water use has become an issue for the Preserve and the surface/groundwater interface of the riparian areas that bisect the Preserve. Finally, small communities near the Interstate 10 corridor and Cochise County have begun to stress the local aquifer and the shallow groundwater areas to the east along the CCNP. This report evaluates historic and current groundwater level trends, water balance and potential threats to groundwater supplies and loss of riparian habitat in the watershed.

1.1 Purpose and Scope

The Cienega Creek Watershed Groundwater evaluation has been developed in conjunction with the current Cienega Creek Watershed Risk Assessment to assist in identifying and mitigating, as best possible, natural and man-made stressors that may be impacting the groundwater system. At this time the County has begun to compile risk assessments of potential threats including drought, depletion of groundwater, land use and mining, and develop appropriate management strategies to reduce or eliminate impacts from these threats to the sustainability of the Cienega Creek Natural Preserve and other County properties within the Cienega Creek Watershed and groundwater basin.

1.2 Overview of Previous Studies

A very large amount of information has been compiled evaluating the Cienega Creek Watershed, especially just prior to and since the establishment of the CCNP in 1986 by the Pima County Board of Supervisors; and the establishment of the Las Cienegas National Conservation Area (LCNCA) in 2000 by the Federal Government. For the Cienega Watershed Risk Assessment a comprehensive annotated

Cienega Creek Groundwater Evaluation Page 2

bibliography was compiled for the effort, and a Groundwater category covers most of the groundwater and related studies (Appendix A). In addition, the Nature Conservancy also compiled a bibliography of the Basin and some related reports from associated areas (San Pedro, Sonita Basin), and provided a link to access these reports (Tiller, et, al, 2011).

A very large body of work for groundwater was also recently completed for the proposed Rosemont Mine Environmental Impact Statement (EIS). Related to groundwater, three groundwater flow models, covering the upper and much of the lower Cienega Creek Watershed were produced evaluating the potential impacts on basin ground water levels of a large proposed mine pit on the eastern pediments of the Santa Rita Mountain front west of State Route 83 and about 11 miles northwest of Sonoita, Arizona. Meyers (2007, 2008, 2010) produced a groundwater baseline report a groundwater modeling report and recalibration describing the projected impacts of the Rosemont mine pit on water levels in Davidson Canyon sub-watershed, the upper and portions of the lower Cienega Watershed for Pima County Regional Flood Control District. Montgomery and Associates (2009a, 2009b, 2009c, 2010) conducted extensive monitor well drilling, aquifer testing and produced an initial and revised modeling report covering a similar area as Meyers (2007, 2008, 2010) evaluated the effects of the proposed Rosemont pit on groundwater and surface water levels for the Cienega Basin. Finally, Tetra Tech developed a similar model as Montgomery with several differences, including a vertical porphyry dike several miles downgradient of the proposed Rosemont Pit (Tetra Tech, 2010).

2.0 Hydrologic and Hydrogeologic Setting

2.1 Subsurface Geology- The lower Cienega Creek Basin north of Cienega Narrows consist of recent alluvium, older alluvium, Pantano formation and bedrock (Chong-Diaz and Matlock, 1995) The recent alluvial deposits are of Holocene age, are unconsolidated and are the most permeable water bearing deposits. The younger alluvium extends from the Cienega Creek floodplain depths of 100-120 feet, has well yields of 10-400 gpm depending on casing size, and is highly productive. Depth to water in the younger alluvium ranges from the surface to 50 feet below land surface (bls). Transmissivity have been measured as high as 200,000 gallons per day/foot (gpd/ft.) of drawdown with specific yields as high as 0.20-0.25 Kennard, et, al, 1988). Since the thickness of this formation is s not large, it is not the major water bearing unit in Cienega Basin, but is the primary media for surface water recharge of storm flow and streamflow.

Cienega Creek Groundwater Evaluation Page 3

Less information is known about the younger alluvium in the upper Cienega Basin. However, the younger alluvium may extend to 200 feet in the upper basin and produce large amount of water in some areas (Boggs, 1980). However, the major water bearing unit in the upper basin is the Tertiary older basin fill alluvium. Montgomery (2009a) calls this unit QTg or Basin Fill-with higher permeability. The older basin fill is also divided into a less productive unit called the Basin –Fill lower permeability (QTg1) and underlies the QTg. They assign the recent Quaternary alluvium as the thin veneer of alluvium on the floodplain of Cienega Creek, and is no more than 100 feet thick from the surface.

The older alluvium or Basin Fill is weakly consolidated and consists of mostly silts, sands and gravels. It is of Pliocene and Pleistocene age and is the major water bearing unit in the lower and upper Cienega Basin. Several differences for the Basin fill are evident between the lower and upper basins. The Basin fill thickness for the lower Cienega Basin is less than 1,000 feet and generally much shallower along Cienega Creek (Chong-Diaz and Mattock 1995). The well yields range from 2-75 gpm and average about 25 gpm. It appears to have limited potential for yielding large amounts of water with lower hydraulic conductivities.

The upper Cienega basin fill has a much larger storage capacity, with a thickness of up to 2,500 feet in the central portion of the upper basin, mostly unconfined and moderately productive (Bittson, 1978; Boggs, 1980). The older basin fill alluvium is the primary aquifer in both upper and lower basins and may be a leaky semi-confined aquifer due to discontinuous sequences of silts and clays with sands and gravels. Montgomery (2009a) cites Harshbarger (1975) as the Basin fill being productive in a 36 square mile area paralleling Cienega Creek mostly in Township 19S, R17E. Transmissivities within this productive zone range from 15,000-40,000 gpd/ft (Bota, 1997). In other areas of basin fill transmissivities are much lower at 500-5,000 gpd/ft. Storativity was estimated at 0.01-0.1 in the upper basin (Bota, 1997).

The Pantano Formation is evident in the lower Cienega Basin. However, it does not appear as present in the upper Basin. The Pantano formation consists of consolidated and cemented sandstone, mudstone and conglomerate with interbedded claystone. Downstream of Pantano dam it appears to lie beneath the younger alluvium and was essentially an aquitard with mostly consolidated clay and silts (Postillion, et, al, 2006). It is

Cienega Creek Groundwater Evaluation Page 4

characterized as very low in permeability with poor well yields. Few wells produce water from this formation (Montgomery,1985). In the Empirita Ranch portion of the basin larger amounts of younger alluvial and basin fill deposits are found. North of Interstate 10, however, these deposits thin and very small amounts of water are contained within these units. Underflow in these areas daylight to become surface water along the creek as bedrock becomes very shallow.

Using geophysical gravity methods, Bittson (1976) and Oppenheimer and Sumner (1980) identified depth to bedrock as deep as 5000 feet near the Pima/Santa Cruz County line east of Sonoita. The deepest wells in this area were 1,500-2000 feet, with basin fill material of lower hydraulic conductivity. Pantano Formation may underlie basin fill in this area and suggests it be the material extending below it.

Bedrock consists of well lithified Mesozoic and Paleozoic sedimentary Rocks with a mix of plutonic, igneous and other sedimentary rocks (Ellett,1994). The underlying bedrock complex and the surrounding mountains yield little water to the system but serve as a primary recharge medium for the mountain fronts. In areas of fractures such as the limestone and dolomite areas, large and smaller fractures can provide movement of water toward the central portions of the basins. Where the bedrock nears the surface along Cienega Creek and Davidson Creek, groundwater is forced to the surface due to the very low permeability of the bedrock. Areas such as the “Narrows” and “Three Bridges” have shallow bedrock underlying Cienega Creek bed and adjacent confining bedrock along the side of the Creek. Few wells produce significant, if any, amounts of water from the bedrock complex. However, if fractures are encountered, yields can be high enough to provide amounts for light domestic and regional Park use such as Colossal Cave Mountain Park. In the mountainous areas west and east of the upper Cienega Basin, bedrock consists of lower cretaceous sedimentary formations (Bisbee Group), Paleozoic Sedimentary and Metamorphic formations. In the Davidson Canyon much of the bedrock area is upper Cretaceous Volcanic rocks (Montgomery, 2009a). These formations also produce small amounts of water for light domestic and stock watering use.

2.2 Recharge- Several sources of recharge provide water to the Cienega Basin, including mountain front, stream channel and underflow. Ellet (1994) summarized mountain front recharge from several sources, including a USGS regression equation (Anderson, et. al,

Cienega Creek Groundwater Evaluation Page 5

1992) for Arizona (rainfall greater than 8 inches), mass balance of chloride ions (Montgomery, 1985), a steady state computer model (Boggs, 1980) and Estimation of Infiltration rates from the geologic formations (Montgomery, 1985). Estimates ranged from 10,650-19,500 AF/yr. However, only one source, the USGS regression equation, estimated mountain front recharge for the entire basin at 16,800 AF/yr, of which 7,700 AF/yr includes the lower basin (Ellett, 1994).

Stream channel recharge or infiltration of storm flow was estimated by several researchers. Infiltration of surface water is related to the duration and magnitude of surface flow. Estimates vary because of the variable flood flows on Cienega Creek and Davidson Canyon. However, based on streamflow depletion estimates in the reaches from Pantano Dam to the Rillito and the Rincon Creek estimates from varied from 240 to 450 AF/mi/day with an average of about 345 AF/mi/day. However, the lower Creek from I-10 to Pantano dam probably has lower recharge rates due to shallow depth to water and less storage capacity because of shallow bedrock in several areas. The area from the narrows to I-10 may approach recharge rates similar to the estimates downstream of Pantano Dam since surface flow is ephemeral and depth to groundwater is over 50 feet bls. Stream channel recharge along Davidson Canyon should be similar to other shallow channels such as Rincon Creek and portions of lower Cienega Creek. These values could range from 240-450 AF/mi/day and is dependent upon the yearly flood flows.

2.3 Water Wells, Use and Pumping

Figure 2-1 shows the wells within the Cienega Creek Basin. A list of the wells is in Appendix B with other site information such as well owner, State registration number (Wells 55), well type, Groundwater Site Inventory (GWSI) identification and water level records. Over 2,000 ADWR recorded wells (not cancelled or never drilled) are listed in the entire Cienega Creek Basin, with the majority of those wells under private ownership (Table 2-1). Fourteen wells are registered under ownership of two municipal water providers in the basin: Vail Water Company in the far northwest and Sonoita Valley Water Company in the far south of the Basin. Forty-eight wells are either under the ownership of Pima County or Pima County Regional Flood Control District, with most of these in the CCNP or Colossal Cave Mountain Park.

Cienega Creek Groundwater Evaluation Page 6

Of the total number of wells registered, only 132 are non-exempt wells (wells pumping greater than 35 gallons per minute) within the Cienega Creek Basin. Of these, ten are within the boundaries of the Tucson Active Management Area (TAMA) that requires annual reporting of groundwater withdrawals. No reporting is available for the non- exempt wells outside of the TAMA. For this report, pumping outside the TAMA was estimated based on the type of use for each well as noted on the application to ADWR and information provided by Tadayon (2005) for water withdrawals outside of Active Management Areas.

Table 2-1. Well Records by Ownership

Entity Number Percentage of Wells of Total Municpal 14 0.7 Private Water Companies, User 52 2.5 Associations, Developments or Well Shares Mining Companies 125 6 Utility Companies 16 0.8

Federal 127 6.3 State 78 3.9 County 48 2.4 Private 1,560 77.2 Total 2,020 100

Exempt wells also have no pumping volume reporting requirements for all of the 1,709 within the Cienega Creek Basin. Pumping from each exempt well, permitted to withdraw up to a maximum of 35 gallons per minute, was estimated at one acre-foot per year based on documentation provided by Pima Association of Governments (2012) and Tadayon (2005). The remaining 300 wells identified in this basin were either not drilled (well was cancelled) or were listed as “other”, meaning that they were strictly used as monitoring wells and not pumped. Pumping was not calculated for 34 of the exempt wells on file because pumps were either not installed or were removed prior to 1984.

The remaining 179 wells in the Cienega Creek Basin were listed as either monitoring or other wells. Monitoring wells were strictly used for water level measurements or for limited water quality testing, so pumping was estimated to be negligible for these wells.

Cienega Creek Groundwater Evaluation Page 7

Most of the wells listed as “other” were drilled for such purposes as mineral exploration, cathodic protection, geotechnical investigation, and soil vapor extraction. None of the wells listed as “other” produced any water so they were not used in the pumping calculations for this report.

Table 2-2 shows the number of wells and associated estimated withdrawals in the Cienega Creek Basin from 1984 through 2014. Pumping volumes ranged from a low of 2,291 AF in 1984 to a high of 4,799 AF in 2012. No reported values for 2014 were available at the time of this report, so an average over the previous 5 years was used. Average annual pumping over the 30-year period was 3,525 AF. Over the last 10 years, the average has increased by more than 1,000 AF (4,589 AF per year) which is the result of residential and commercial growth in the Town of Vail on the far northwestern end of the basin and a steady influx of new well construction in the area of the Jay-Six Ranch subdivision on the northeast of the basin.

The majority of pumping within the Cienega Creek Basin occurs over three, localized distinct areas: Vail, Sonoita and the Jay-Six Ranch communities (Table 2-3). The community of Vail, at the downstream end of Cienega Creek, contributes more than one-quarter of the total pumping in the watershed, mostly for municipal purposes. Sonoita, at the upstream end of Cienega Creek near the Pima/Santa Cruz County line, contributes about 30% to the total pumping with almost an even split between municipal, domestic (individual household wells) and agriculture (irrigation and stock) water uses. The Jay-Six community consists mostly of domestic wells that contribute about 13% to the total withdrawals in the watershed. Pumping in the Jay-Six community could be a cause for some of the groundwater induced movement to exit the Cienega Creek Basin and move eastward into the San Pedro River Basin, as described by Ellet (1994). The remaining 30% of pumping occurs over the vast majority of the Cienega Creek Basin and consists of a mix of domestic, mining and agricultural water uses.

1 Withdrawals from exempt wells are estimated at one acre –foot per year per well (PAG, 2012; Tadayon, 2004).

2 Agricultural withdrawals are estimated using the acres of irrigation provided in the ADWR well application and the consumptive water use for the type of crop planted (Tadayon, 2004)

3 Industrial and Mining withdrawals are based on well pump rates and the hours of operation (Tadayon, 2004).

4 Domestic withdrawals are estimated to be the same as withdrawals from exempt wells as described above.

5 Includes both reported and estimated pumping. Municipal withdrawals are provided by ADWR (2015) for non- exempt wells in the TAMA. Municipal withdrawals are estimated by Tadayon (2004) outside of the TAMA through 2000 and by RFCD through 2014 using projected census figures provided by ADWR (2009).

Figure 2-2 illustrates the influence of stream runoff and total pumping on groundwater levels in the lower basin over the last 20-30 years. Total annual streamflow volume is displayed for the USGS gage at Pantano Dam at the downstream end of the basin. Pumping volume reflects the entire basin, but much of this is at the downgradient end in the Vail Water Company Service area and a reflection of numerous domestic wells in the lower basin area. All of the well hydrographs are in the lower Cienega basin. Overall, a declining depth to water trend is apparent in all of the wells in this area, in part due to the steady increase in pumping volumes since the mid-1990’s. Significant recoveries in water levels occurred shortly after high volume runoff years in 1998-2000 and 2006- 2008, and to a lesser extent after the moderate volume runoff years in 2010 and 2014. However, these recoveries only provided a brief offset to the general water-level declines, as monitor well water levels significantly decline during the lower volume runoff years that follow.

Similar records in the Upper Cienega Creek Basin were sparse, making it difficult to show long-term influence of annual flow volumes and pumping on groundwater levels (Figure 2-3). The USGS gage at the downstream Narrows was also used from 2002- 2014. For the most part, groundwater levels for available wells appear to be fairly steady throughout the upper basin, with only small recoveries occurring as a result of wetter years or small declines occurring after dry periods. The general trend of groundwater level decline since the 1980’s is consistent in all but one of the wells with long-term records, with only the Empire Gulch area (Oak Tree LLC Well) showing a modest

Cienega Creek Groundwater Evaluation Page 10

increase. Wells with shallow water levels with long term records were not available. Pumping in the upper basin has not increased by very much over the last few decades, which may account for the mostly steady groundwater levels in this area, at least for wells with depths to water of over 100 feet.

3.0 Groundwater Level Evaluation The most recent comprehensive water level data were compiled to construct groundwater elevation and depth to water contour maps. Longitudinal water level profile maps of the lower and upper Cienega Basin were constructed. In addition, historical water levels and hydrographs were evaluated to provide historical and current water level trends and the relationship of base flow and length of stream flow with fluctuating groundwater levels.

3.1 Current Water Level Conditions Recent water-level data is fairly extensive along the main channel of Cienega Creek and portions of its tributary watercourses, but is sparse in the upland areas of the basin, except for the developed area east of Empirita Ranch. Water levels for the area were collected from a few sources: ADWR’s Groundwater Site Inventory (GWSI), Pima Association of Governments’ monitoring program for CCNP and the Bureau of Land Management’s monitoring program for Las Cienegas National Conservation Area. Additional water-level data from the GWSI and Wells 55 databases from previous years were used to supplement the 2015 data as needed. A total of 68 wells were used to develop a rough estimate of current groundwater conditions in the entire Cienega Creek Basin.

Figure 3-1 displays water surface elevations for the Cienega Creek Basin as of January/February 2015. Groundwater movement in the most upper portion of the basin is generally to the north, following the path of Cienega Creek until it reaches Fortynine Wash, 5.25 miles northeast of Empire Ranch. Groundwater then heads northeast for almost 7 miles to the southern end of Empirita Ranch, where it begins to turn northwesterly. Groundwater movement continues its northwesterly direction to the end of the basin near the town of Vail. In the Davidson Canyon area groundwater moves northeasterly off the Santa Rita Mountains and then bends north and northwesterly as it joins Cienega Creek.

The slope or gradient of the water table varies greatly through the Lower Cienega Creek Basin (Figure 3-2, Longitudinal Profile A-A’). The water-level slope from Empirita Ranch to

Cienega Creek Groundwater Evaluation Page 11

just upstream of the Interstate 10 bridge crossing averages about 62 feet/mile (0.0118 ft/ft). The slope then flattens to about 16 feet/mile (0.0030 ft/ft) between the Interstate 10 crossing and Pantano Jungle. The gradient increases to about 50 feet/mile (0.0095 ft/ft) for the next 8.25 miles from Pantano Jungle to Pantano Dam. Downstream of the dam, the water table drops dramatically at a rate of roughly 390 feet/mile (0.0739 ft/ft) to just west of the Colossal Cave Road crossing. This is probably reflective of both the shallow bedrock conditions downstream of Pantano Dam to a Schist outcrop, and then a plunging of the bedrock at a normal fault westward to Colossal Cave Road; and the influence of several high volume Vail Water Company public supply wells.

Water surface elevations in the upper basin range from approximately 4700’ in the upstream portions of the watershed to approximately 4300’ near the downstream portions in the vicinity of the “Narrows”. Water level gradients range from shallow (30 ft/mile) in the western flank, to moderate (70 ft/mile) in the southern flank, and steep (150 ft/mile) in the eastern flank of the watershed. Figure 3-3 is a profile (B-B’) of the Upper Cienega Creek Basin as it follows along Cienega Creek. The slope or gradient of the water table along this profile is fairly steady, ranging from 24.5 feet/mile (0.0046 ft/ft) to 37 feet/mile (0.007 ft/ft). Several shallow piezometers indicate the presence of surface flow for approximately 4 miles along Cienega Creek from its confluence with Oil Well Canyon to the confluence with Oak Tree Canyon).

In the lower basin, groundwater depth to water from various wells range from 19 feet below land surface (bls) near the middle of CCNP to almost 600 feet bls at the far northwest corner of the basin, approximately two miles downstream of Pantano Dam (Figure 3-3). The presence of perennial surface flow at CCNP indicates even shallower groundwater depths in this area, which are not shown by any monitoring wells.

Based upon a study performed by Pima Association of Governments (PAG, 2000), a number of shallow groundwater areas (SWGA’s) were identified. SGWAs are primarily defined as areas where the water table is above 50 feet bls (PAG, 2008, 2012), within the Cienega Creek Basin (see Figure 3-4). In the lower basin, narrow strips of shallow groundwater closely follow the main channels of Cienega Creek and two of its major tributaries, Davidson Canyon Wash and Agua Verde Creek. Broader SWGA’s are in the

Cienega Creek Groundwater Evaluation Page 12

upper portions of Cienega Creek basin within BLM’s LCNCA and in Barrel and Gardner Canyons.

Depth to groundwater measurements in 2015 suggest that the SWGA along Cienega Creek has receded quite a bit since 2000 within the lower basin. Groundwater levels have declined below the 50-foot threshold for roughly over 5 miles between Empirita Ranch and Interstate 10 and for about one quarter of a mile downstream of Pantano Dam.

In the upper basin, the majority of the wells providing recent water level data are within the central valley. Little data is available across the western and eastern flanks of the upper basin. To construct current water level contours of the upper basin, 19 wells with water level measurements within the last two years (2014-2015) were utilized. ace elevations in the upper basin range from approximately 4700’ in the upstream portions of the watershed to approximately 4300’ near the downstream portions in the vicinity of the “Narrows”. Water level gradients range from shallow (30 ft/mile) in the western flank, to moderate (70 ft/mile) in the southern flank, and steep (150 ft/mile) in the eastern flank of the watershed.

BLM field surveys and measurements taken from unregistered, shallow piezometers indicate perennial surface flow along Cienega Creek and some of its major tributaries in the upper basin. Available data from wells in the ADWR database indicates a range of water levels from shallow (32 ft.) near the main channel of Cienega Creek to moderately deep (over 200 ft.) in the surrounding mountain foothills.

3.2 Historical Water Levels Seven wells were available in the Lower Cienega Creek Basin with reliable records from the early 1980’s and 1990’s that continued through 2015 (ADWR, 2015; PAG, 2015). A total of three time periods were evaluated for water level changes: an overall 30-year period since 1984, an intermediate 20-year period from 1995 to 2015, and a most recent 10-year period from 2005-2015. Figure 3-5 is a map of the Cienega Creek Basin with hydrographs geographically spread across for comparison. Some of the hydrographs are later provided in larger view for discussion.

Cienega Creek Groundwater Evaluation Page 13

A summary of water level changes in the lower Cienega Creek Basin for the 30-year, 20- year and 10-year periods is provided in Table 3-2. Five representative wells indicated an average rate of decline of 0.87 ft/yr. for the average 31-year period, with the most significant decline occurring at the downstream end of the basin near Colossal Cave Road. An even greater rate of decline (0.94 ft./yr.) was experienced over the last 20 years as shown by three of the same wells used for the 30-year evaluation and two other wells with representative data. The rate of decline dropped to 0.52 ft./yr over the last 10 years, with a total of 10 wells represented, including one well at Empirita Ranch that showed a significant recovery of 0.68 ft./yr. since 2005. Reasons for larger 30-year and 20-year declines may be that the basin was in a unusually wetter period from 1978-1994 followed by a steady drought from 1995-2005; with a slight drought lessening for summer rains from 2006-2012 (Shields, et. al., 2015). Water levels were at their peak in in 1985-1994, so the overall decline during those 20- and 30-year periods would be substantial.

In the upper basin, wells with historical water level data were evaluated for water level changes over decadal time intervals. Water level changes were calculated between the most recent water level measurements (2014-2015) and those measured approximately 10 years (~2005), 20 years (~1995), and 30 years (~1985) ago. All nine (9) wells evaluated demonstrated water level declines over the last ten years, ranging from minor declines (-0.1 ft/yr) to extreme declines (-2.5 ft/yr). The average 10-year decline for these wells was -0.6 ft/yr which is probably reflective of the current regional drought. Over the last twenty years, six (6) of the wells demonstrated water level declines ranging from negligible (-0.02 ft/yr) to significant (-0.5 ft/yr). The average 20-year decline for these wells was -0.3 ft/yr showing a transition from a wetter period to the current regional drought. Over the last thirty years, seven (7) wells demonstrated declines ranging from negligible (-0.03 ft/yr) to significan(-0.9 ft/yr). One well showed a slight recovery of 4.6 feet. The early 1980s was a period when the area was beginning to climb out of a summer drought period that ended in 1983 (Shields, et, al., 2015). The upper watershed shows the largest declines over the last ten years and could be reflective of the current drought and increased pumping.

3.3 Influence of Flood Flows, Base Flows and Cumulative Annual River Flows on Water Levels and Stream Channel Length Monitor well water levels and stream flow have only been consistently reported since 1994 for the lower Cienega Creek Basin making it more difficult to evaluate the relationship between stream flow and groundwater levels in this area. However, observations recorded since the late 1990’s do appear to link annual volumes of stream flow with depth to water measured in wells, with peaks in water levels occurring during or shortly after high volume flow years and significant declines in water levels during much drier years (Figures 3-6 and 3-7).

The relationship of stream flow length, base flow and depth to groundwater has been evaluated by several researchers. Powell and others (2014) looked at both streamflow volume and stream length in relation to varying water levels in monitor wells within the CCNP in both lower Cienega and Davidson Creeks. They found a strong correlation between stream flow volume and stream length with depth to groundwater in monitor wells in Cienega Creek and Davidson Canyon areas. Reductions in stream flow length appear to show a concomitant decline in nearby monitor wells. As such, future land use activities that will make a demand on available upstream water will have an effect to reduce base flow, length of stream flow and depth to groundwater.

Consistent annual groundwater data in the upper Cienega Creek Basin are available since 1990. However, stream flows in the upper Cienega Creek Basin have only been measured since 2001 at the USGS gage, approximately 1.8 miles downstream of the Fortynine Wash (Sonoita gage). In addition, consistent shallow groundwater level monitoring has only been done in this area since 2007. Therefore, the relationships of water levels to flow and length of flow in this area are less defined in the long term. Deeper groundwater levels in this area have been not changed significantly over the last few decades, but some minor recoveries and declines in correlation to flows were measured at the far downstream gage at Pantano Dam (Figure 3-7). A stronger correlation of groundwater levels and more local flows measured at the Sonoita gage is noticeable in the shallower monitoring wells over the last few years, from 2011 to 2015 (Figure 3-8).

Cienega Creek Groundwater Evaluation Page 17

Recent regression analyses were performed on one well with deep water levels and one with shallow water levels in the Empire Gulch Area, tributary to Cienega Creek. The depth to water for each well versus length of flow on upper Cienega Creek from 2006- 2014 were plotted to assess the relationship (Figure 3-9) The relationship accounted for about 60% of the variation for these wells. The shallower well showed a larger decline with less stream flow length than the deeper well. More data is needed to refine this relationship.

3.3.1 Pre-1977- Extent and Available Data Annual flow volumes are available from the Pantano at Vail stream gage from 1960 through 1973 (Table 3-3). The average annual stream volume during this time was 4,943 AF, with a maximum annual volume of 9,540 AF occurring in 1964 and a minimum annual volume of 1,490 AF in 1969. This average is approximately 25% greater than the periods of 1995-2004 and 2005-2014, suggesting a wetter period of time for the Cienega Basin as a whole. Water level records are very limited before 1977, with most of the water level measurements available only at the time of well construction (Figure 3-5). For the few wells in the Lower Cienega Basin with water level data prior to 1977, it appears that the groundwater table was at a much similar elevation if not lower than current water table elevation. This could be due to the fact that this area, along with the rest of the State of Arizona, was under an extreme drought from 1942-1964 (Pima County 2001) that would have significantly lowered the water table. The Upper Cienega Basin wells with data before 1977 indicate a much higher water table during this time in comparison to current levels. However, there appears to be significant pumping in the vicinity of these wells over more recent times, which could account for the lower water levels reported.

3.3.2 1977-1993. Period of Wetness and Larger Winter Precipitation No annual flow volumes are available along Lower Cienega Creek for much of this time period as the USGS only recorded annual maximum discharges for Water Years 1975- 1989 in this area (USGS, 2013). However, it can be assumed that the annual volume for the 1983 Calendar Year was high based upon the extreme maximum discharge of 12,000 cfs at the Pantano Wash gage near Vail. This peak flow occurred on October 2, 1983 as a result of heavy rainfall produced by tropical storm Octave from September 27 to October 3 (Roeske et. al.,1989). Water level records throughout the basin are very sparse before 1995, so it is difficult to analyze how groundwater reacted to the increase flows along Cienega Creek during the late 1970’s through early 1990’s. However, groundwater levels were at their highest in 1995, suggesting that a large amount of recharge was occurring in the area at this time.

Cienega Creek Groundwater Evaluation Page 19

3.3.3 1994-2000. Beginning of Drought and Less Winter Precipitation A significant reduction in annual flow volumes were recorded at the Pantano Dam stream gage from 1994 through 1997 due to less winter and summer precipitation in the surrounding area. As a result, groundwater levels in the Lower Basin declined from 1.3 feet to 18.3 feet during this time, with more declines occurring within the ephemeral portion of Cienega Creek between Empirita Ranch and Pantano Jungle and at the well near Pantano Dam. In 1998, the Pantano gage recorded its highest annual flow (11,170 AF) in recent decades that was a result of significant winter and summer runoff in the area. Coupled with the annual volume in 2000 (8,271 AF), which was mostly attributed to summer runoff, the increased amount of flows during the end of this period had a significant effect on groundwater levels, with recoveries ranging from 1.4 feet in the perennial portions of the basin to almost 19 feet near Pantano Dam (Figure 3-6).

The few deep wells with consistent records in the upper Cienega Creek Basin showed mostly steady water levels during this time period. Three of the wells did indicate a significant decline from 1998 to 2000, which is most likely in response to the very dry year in 1997. All of the wells showed modest to moderate recoveries (0.2 feet to 7.8 feet) in water levels after the high annual volume years of 1998 and 2000 (Figure 3-7).

3.3.4 2001-2005. Less Winter and Summer Precipitation. This five year period was significantly dry, with annual flow volumes falling below 2,600 AF for each year on record at the Pantano Dam stream gage. Groundwater levels in the lower basin were significantly impacted, with declines ranging from 3.8-4.7 feet in the perennial/intermittent portions of Cienega Creek and Davidson Canyon, and from 9.7- 14.8 feet in the ephemeral portion of Cienega Creek from Empirita Ranch to Pantano Jungle. The well near Pantano Dam still had the most significant decline at 19 feet during this time (Figure 3-6).

Annual flow volumes in the Upper Basin were first recorded in October 2001 with the installation of the stream gage along Cienega Creek near Sonoita (USGS, 2002). Much like the Lower Basin, annual volumes in the Upper Basin were relatively low from 2002 through 2005, ranging from 636 AF to 860 AF. Water levels in deeper wells remained steady for the most part. Data for shallow groundwater was not available (Figure 3-7).

Cienega Creek Groundwater Evaluation Page 20

3.3.5 2006 – 2014. More Summer Rains and Less Winter Precipitation The Cienega Basin has seen an erratic pattern of wet and dry years over the last decade, which has resulted in a similar responsive pattern of rise and fall in groundwater levels. Annual flow volumes at Pantano Dam were all higher than 5,500 AF from 2006 through 2008, resulting in substantial recoveries in monitor well water levels throughout the lower basin, ranging from almost 4 feet at Davidson Canyon to over 15 feet near Pantano Dam. Water levels dropped substantially (up to 13.8 feet) after one of the driest years (driest in recent records) in 2009. Water levels over the last five years have slightly risen and fallen with the occurrence of moderate annual flow volumes (near 3,000 AF) from 2010 to 2011, followed by low annual flow volumes (below 1,300 AF) from 2012 to 2013, and an annual flow volume over 3,600 AF in 2014. This resulted in moderate recoveries for most wells by 2015( Figure 3-6).

Figure 3-8 provides a more detailed look at groundwater levels along the upper portion of Cienega Creek in relation to flow volumes in the short term. Over the last few years (2011-2015), monthly groundwater levels taken from five shallow piezometers along the Creek show a distinct relationship to daily flow volumes provided by the USGS at their Sonoita stream gage. Groundwater levels predominantly recover about one to two feet after summer runoff events, with a peak occurring around January, and then begin to decline from early Spring through June.

Similar recoveries and declines appear in monitor Well PS-1, downstream of Pantano Dam after monsoon rains (Figure 3-10). In the lower watershed, shallow water levels showed a strong response after substantial flows in the following several months after large monsoonal seasons from 2007-2013 (Figure 3-10). Only in the winter of 2010 did significant flow allow for a rebound of water levels in the monitor well. However, the well has dropped from 49 feet bls in April 2007 to 58 feet bls in April 2013. The lack of substantial winter runoff appears to play a part in this downward declining trend.

3.3.6 Groundwater Level Declines and Recoveries-Entire period summarized. Declines in groundwater levels measured in 11 monitor wells throughout the Cienega Creek Basin ranged from almost one-half a foot to just over 35 feet from 1995-2014, the approximate time period when drought conditions began. The average decline of 0.53

Cienega Creek Groundwater Evaluation Page 21

ft/yr. for this period is just a little more than the average decline for the overall 30-year record, which was calculated at 0.46 ft./yr. from 1983-2014. The average rate of decline over the last 10 years (2005-2014) turned out to be exactly the same as the 20-year record for the whole basin.

Average groundwater declines in the lower Cienega Creek Basin more than tripled the average declines in the upper basin over the last 20 years, with the greatest amount of decline occurring within the Town of Vail near Colossal Cave Road. Comparison of the 30-year average declines in the two sub-basins was even greater, with the lower basin declines being over 4.5 times greater than those in the upper basin. Oddly enough, average declines over the last ten years in both basins was almost the same, with the upper basin being slightly higher (0.6 ft./yr.) than the lower basin (0.52 ft./yr.).

Annual groundwater levels were the most stable near the perennial reaches of Cienega Creek, with only little responses to high and low flow volumes. The correlation of annual flow volumes to groundwater levels is much more prominent in the wells within the ephemeral reaches (near Empirita Ranch and at the east and west ends of CCNP), where significant recoveries occur after the high flow volumes in 1998-2000 and from 2006-2008, followed by sharp declines during subsequent dry years (Figure 3-6). These areas have more storage capacity.

3.4 Water Balance Discussion- Comparison of Upper and Lower Basins

From 2005-2014, the average annual stream volume at Pantano Wash near Vail gage was 3,705 AF (Table 3-4). This volume is almost the same as the average annual amount from 1995-2014 (3,728 AF), indicating appreciable amounts of storm water were available to recharge the creek bed and tributaries over the last 20 years. However, a closer look at when flows occur during each year tells a different story. Upon review of seasonal precipitation departures from the average, the District (Shields, et, al, 2015) determined that there has been a shift in patterns from a balance of Summer and Winter rainfall prior to 2005 to a more dominant Summer rainfall since. More runoff, in the form of flash floods, is likely to occur with the higher intensity thunderstorms in the Summer than with the more gentle rains and snow fall in the upper elevations generating low

Cienega Creek Groundwater Evaluation Page 23

flows, that occur in the Winter. This results in less overall mountain front and stream channel recharge within the basin from 2005-2014 than over the previous ten years (1995-2004). This could explain why groundwater levels in the upper basin have dropped at a significantly higher rate over the last decade.

Groundwater levels in the lower basin, however, have declined at a lower rate over the last decade when compared to the overall 20-year and 30-year records. One explanation for this phenomenon could be that greater amounts of flow from Summer runoff reaches the more ephemeral reaches of Cienega Creek, along the eastern and western ends of CCNP in the lower basin, that are able to recharge these higher flows and thus reduce the rate of decline in the groundwater table. A more likely explanation is that groundwater levels were already at a very low point in 2005 due to five successive years of drought, as noted by very low annual flow volumes. Thus, the water level difference would be much lower in comparison to the early 1980’s and the mid-1990’s when water levels were at or near their peak due to unprecedented wet years and high annual flow volumes. Some wells, including Jungle and Del Lago, in the lower basin showed the largest declines from 1995-2005 at as high as 1.5-1.8 ft/yr as a result of a transition from a wetter to drought period (Figure 3-6).

Overall pumping in the Cienega Creek Basin from 2005-2014 ranged from 4,422 AF/yr. to 4,766 AF/yr., for an average of 4,589 AF/yr (Table 3-3). This volume is almost a 24% increase (1,084 AF/yr.) compared to the previous decade, 1995-2004. The increase is mostly attributed to a greater amount of municipal pumping in the community of Vail and an increase in the number of exempt wells constructed near the Jay-Six Ranch since 2005. Both of these areas are in the lower basin, which experienced a pumping increase near 37% over the last decade. In comparison, the upper basin only experience a 10% increase (241 AF/yr) during the same period.

Over the last 10 years, the average decline of groundwater levels over the entire Cienega Basin was about 0.5 ft/yr. This is similar to the average over the last 20 years (since 1995) and the overall 30-year average for the entire basin since 1982. The upper basin has seen more declines over the last decade than in previous 20-year and 30-year periods (Table 3-2), suggesting that the perennial and intermittent portions of the creek are susceptible to decreased flows and even a small increase in well pumping over time. The lower basin has actually seen smaller declines over the last decade than for the 20-year and 30-year record, despite the

Cienega Creek Groundwater Evaluation Page 24

increased pumping pressure in this area and similar overall annual flow volumes recorded near Pantano Dam. The steeper 20-year and 30-year declines are probably because water levels in the mid-1980s and mid-1990s were at their highest during an unprecedented wet period from 1978-1994, so the difference to 2015 would be larger compared to the 2005-2015 when drought dominated beginning in 2001, abated slightly 2006-2008 and resumed 2009-2015. Large annual flow volumes recorded from 1998-2000 and from 2006-2008 have helped to keep groundwater levels from severely declining in the Cienega Basin during the latest drought period on record. This drought has been documented by several researchers who show a gradual decline in water storage in the lower basin where the median base flow at Pantano Dam has consistently trended downward from 1.5 cfs in 1990 to less than 0.3 cfs by 2011(Powell, 2013).

4.0 Discussion of Previous Modeling Studies Several modeling studies have been performed over the last 35 years. In the 1980s and 1990s several master’s theses and doctoral dissertations have been done at the University of Arizona with some developing conceptual and computer models assessing the flow system and water quality of the Cienega Basin. Boggs (1980) developed a finite element model of the upper basin using a range of estimated storativity values. Some values of storativity with a given projected future pumping of 10,000-14,000 AF/yr for a proposed Anamax copper mine indicated that Creek base flow would diminish significantly and water level declines would be in the tens and hundreds of feet in the central upper basin. These models indicated significant water-level declines as the result of high volume pumping in the upper and lower Basins from mining or residential development and suggested levels that could threaten the riparian habitat along the Cienega Creek. Two three dimensional modeling studies were performed on the Upper and lower Basins. Bota (1996) developed a modular three-dimensional finite difference groundwater flow model (MODFLOW) used to investigate the interaction between the surface and groundwater in the upper Cienega Creek Basin. Moderate proposed pumping (550 AF/yr) in Sonoita –Elgin area indicated base flow would be diminished slightly at the Narrows. Chong-Diaz (1995) used a Finite Element Three Dimensional Model to simulate the effects of pumping in the lower Basin. Introduction of pumping of 2.2 cfs (990 gpm or 1,600 AF/yr) in areas near Empirita Ranch would greatly affect the perennial flow of the Cienega Creek Natural Preserve and cause significant drawdown to shallow groundwater in the vicinity.

In the past 10 years conceptual and three-dimensional flow models have been developed covering the mid-upper and portions of the lower Basin evaluating the impacts of the proposed Rosemont

Cienega Creek Groundwater Evaluation Page 25

mining pit, on the water surface elevation of these areas. The three major models, Montgomery (2008, 2009); Tetra Tech (2010) and Myers (2008, 2010) looked at the specific declines resulting from the Rosemont pit redirecting groundwater and changing gradients. The models were summarized regarding decline impacts projecting from 50,100 to 1000 years in the future. The models were all steady state and did not account for the current pumping impacts or a range of climatic conditions. None of these were superimposed over the current declining water level conditions in the Basin. As such, these models were not adequate in projecting the overall impacts of current and future pumping, and a range of climatic conditions.

5.0 Groundwater Quality and Geochemistry Groundwater quality monitoring within the Cienega Creek Natural Preserve has been limited. As part of its efforts to have Cienega Creek designated as an “Outstanding Water of Arizona”, Pima County had groundwater samples collected and analyzed from two wells between 1988 and 1989 (Fonseca et. al. 1990). Constituents analyzed during this sampling period included nutrients, major ions, trace metals and some miscellaneous elements (hardness, turbidity, Total Suspended Solids, Total Dissolved Solids and alkalinity). These efforts complemented the groundwater sampling and analyses that was conducted by Errol Montgomery and Associates (1985 to 1990) for the Empirita Ranch Hydrogeologic Monitoring Program. More recent samples (2014-2015) have been collected from two other wells by the District and analyzed for major ions and isotopes to determine water types and source of origin. In addition, the University of Arizona has recently collected and analyzed groundwater samples from a number of wells throughout the Davidson Canyon watershed for isotopic constituents (Tucci and McIntosh, 2015). A summary of the analyses and associated data is presented below.

Wet Chemistry A summary of wet chemistry analyses (cations and anions) from four wells in the CCNP is in Appendix C. The predominant cations in both the Cienega Well (55-631733) and the Jungle Well (55-627729) is calcium at 52% and 57% respectively. Both wells also have equal remaining amounts (in the lower 20% range) of magnesium and sodium plus potassium. Both of these wells intercept recent alluvial deposits and recent recharge of stormwater, which accounts for the similarities in cation exchange. The predominant cations in both the Del Lago #1 Well (55-602949) and Davidson Bar V Well (55-502959) are sodium plus potassium at 42% and 50% respectively. The remaining amounts of cations differ in the two wells, with Del Lago #1 having more calcium (38%) than magnesium (21%) and Davidson Bar V having more magnesium (31%) than calcium

Cienega Creek Groundwater Evaluation Page 26

(18%). These two wells intercept different geologic units, with Del Lago #1 occurring in the Pantano Formation and some limestone. Davidson Bar V in granitic bedrock, which may account for the differences in the cation exchange compared to each other and to the other two wells that were evaluated. In addition, these two wells may show a progression of ion exchange from calcium to sodium as a result of movement of mountain front recharge from calcium bicarbonate rainwater to a sodium dominated water similar to the upper basin (Huth, 1997).

As expected, the anions for the two well waters within the recent alluvium (Cienega and Jungle) also follow a similar pattern. The predominant anion in both wells is sulfate (around 54%) followed by bicarbonate (near 43%) and then chloride (less than 3%). Del Lago #1 also predominates in sulfate, but at much higher levels (90%) than any of the other wells. Much smaller amounts of chloride (6%) and bicarbonate (4%) occur within this well. Gypsiferous beds within the Pantano Formation is the most likely source for the increase sulfate content at Del Lago #1 (Fonseca et. al., 1990). The predominant anion in Davidson Bar V is bicarbonate (73%), followed by near equal parts of chloride (15%) and sulfate (11%). Isotope samples taken from the Bar V well in 2014 plotted in an areas below the meteoric water line and what could be classified as recharge water in higher colder elevation areas (Oxygen -8.8; Deuterium -68). The source of high sodium in this well may be due to cation exchange from recharged rain water in the mountain fronts of calcium to sodium. Similar transformations have occurred in alluvial basins and the upper Cienega Basin with water evolving from a calcium- bicarbonate at the mountain fronts to a sodium –bicarbonate type in the central basin (Huth, 1997; Robertson 1991).

Figure 5-1 is a trilinear diagram that visually displays the similarities and differences in the four wells located at CCNP. Based upon the analyses presented, the groundwater underlying the Cienega and Jungle Wells in the recent alluvium along Cienega Creek is a calcium sulfate bicarbonate type. These wells are shallow and do not appear to have completed ion exchange from the mountain fronts and may be dominated by river recharge and a mix water influenced by underlying clays and gypsum. Water intercepted by Del Lago #1 within the Pantano Formation near the Pantano Dam is a sodium sulfate type. This well may have completed ion exchange with calcium dominated mountain front recharge, but could potentially be intercepting large amounts of sulfate dominated gypsum and clays typical of a secondary detachment fault in the area. Davidson Bar V intercepts sodium bicarbonate water within the fractured bedrock along Davidson Canyon Wash and may be typical of the transformation of cation exchange of rain water in the mountain fronts to ground waters typical in transit to the central basin.

Cienega Creek Groundwater Evaluation Page 27

Figure 5-2 is a trilinear diagram that visually displays the similarities and differences in the four wells located at CCNP and several surface samples along Davidson creek and Cienega Creek. The Cienega Creek surface water samples are very similar to the nearby shallow monitor wells Jungle and Cienega Wells, plotting as calcium sulfate-bicarbonate waters. Documented gypsum beds and clay areas in the lower Cienega Creek area along with elevated total dissolved solids (TDS) show th influence of the these features on the water quality. The Del Lago well appears to tap a water that is a blend of nearby stream channel, mountain front recharge and older water from the Rincons. The sodium-calcium-sulfate water from this well may be older water tapping lacustrine gypsum from reworked Permian strata (Eastoe, 2004).

Davidson Canyon Creek has a different quality and water type and appears to be a lower TDS (Less than 500mg/l), mostly a calcium-bicarbonate type . One exception is the Davidson Bar-V Well which is a sodium-bicarbonate water, possible reflecting a cation exchange with calcium dominated rainwater in the mountain front areas.

Oxygen & Hydrogen Isotopes Isotopic compositions of water samples can provide a useful tool for investigating hydrological processes in surface water and groundwater systems. Isotopic fractionation processes lead to the utilization of oxygen and hydrogen isotopes from precipitation, surface water and groundwater as natural tracers in the environment. In surface water and groundwater, oxygen- 18 (18O) and hydrogen-2 (deuterium; D) can provide an indication of both water source, water mixing, and any isotopic fractionation caused by evaporation. Water that evaporated from the oceans to form atmospheric water is depleted in the heavier isotopes, oxygen-18 and deuterium, relative to their concentration in seawater. In precipitation, the oxygen and hydrogen isotopes fractionate in a linear way as a function of temperature, with heavier isotopes preferentially “raining out” at higher temperatures, causing the isotopic composition of precipitation to vary seasonally and with elevation along a linear trend called the Meteoric Water Line. Because differences between a collected sample and a standard can be measured in the lab more precisely than absolute isotopic values, stable isotope ratios are reported as differences (“δ” delta notation) compared to a known standard (VSMOW), in units of parts per thousand (‰ or per mil).

Cienega Creek Groundwater Evaluation Page 28

In the Cienega Creek watershed, most isotopic analyses to date are from the Davidson Canyon watershed and lower Cienega Creek. Figure 5-3, used with permission from Tucci and McIntosh (2015), includes the available lower Cienega Creek and Davidson Canyon watershed δ18O and δD results from University of Arizona, Pima Association of Governments, Pima County Flood Control District, and others. The graph includes data points for the average summer and average winter precipitation from Barrel Canyon and Davidson Canyon, shown as the blue and red squares that plot above the Local Meteoric Water Line. The average winter precipitation values match Tucson Basin average winter precipitation values, but average summer precipitation values are more enriched than Tucson Basin summer values, possibly due to local monsoon convective influences or normalization of the Tucson basin data to the amount of rainfall (Tucci and McIntosh, 2015).

The groundwater, spring, or surface water δ18O and δD results shown in Figure 5-3 are clustered around the local average winter precipitation result, which indicates that groundwater and stream flow, are dominated by winter recharge. Most of the groundwater, springs, and surface water data plots below the Local Meteoric Water Line, providing evidence of evaporation prior to recharge and surface water flow.

Pima Association of Government (2003) found that although upstream and downstream Davidson Creek Wash stream flow samples had similar solute water chemistry, the δ18O and δD results from upstream (near I-10) “reflects a higher-elevation water source” compared to results from a surface water sample site closer to the confluence of Cienega Creek. Data in Montgomery and Associates (2009) also indicates that Davidson Canyon Wash surface flows generally reflect a more isotopically depleted δ18O and δD water source compared to Lower and Upper Cienega Creek stream flow results.

Questa Spring, near the upper reach of Davidson Canyon Wash at ~4600’, is isotopically distinct from most other Davison Canyon springs, wells, and surface waters (Montgomery and Associates, 2009; Tucci and McIntosh, 2015). In Figure 5-3, the Questa Spring results are the cluster of “Springs” results in the -9.5 to -10.5‰ range, adjacent to one Davidson Canyon Wash surface water sample taken from 10 miles downstream at 3519’ elevation with a δ18O of -9.9 ‰ and δD of -72‰ (Dr. Jennifer McIntosh, unpublished data). The Questa Spring results cannot be entirely explained by altitude effects, as other higher elevation spring data from Montgomery and Associates (2009) do not have similarly depleted δ18O values. The depleted δ18O and δD

Cienega Creek Groundwater Evaluation Page 29

results indicate that Questa Spring and the isotopically-similar Davidson Canyon Wash surface water sample are sourced by groundwater with a more unique source that is likely less impacted seasonal recharge from modern precipitation. Some, but not all, higher elevation well sample results included in the Montgomery and Associates (2009) study have δ18O results that are similar to the Questa Spring results, but with less depleted δD indicating less evaporation effects. Most of the sampled wells are two or more miles west of the Questa Spring site, around the proposed Rosemont mine site. These isotopically lighter samples may be from a separate groundwater source, one that has less interaction with modern precipitation compared to most other sites sampled.

Sulfur Isotopes Sulfur isotopes from stream, spring, and groundwater samples are used to determine groundwater source, as sulfur in rocks readily affects groundwater sulfur values and different rock strata (e.g. igneous, sedimentary, evaportites, etc.) have distinct sulfur signatures. To best interpret sulfur data, analysis must include both δ34S and δ18O from SO4. In addition, analysis of local rock strata and precipitation provide a local calibration for results. Researchers from the University of Arizona have completed primary analysis from a suite of Davidson Creek basin groundwater samples collected from within a 30 mile radius. The δ34S values typically range from 0.0 to 5.8‰, with a δ18O from SO4 range that indicates likely relationship with sulfate from sulfide dissolution in igneous and sedimentary rock strata, and mixing with atmospheric SO4. Two samples had δ34S values of 15.0 and 16.1‰, indicating localized groundwater interactions with evaporitic minerals such as gypsum (Dr. Jennifer McIntosh, unpublished data). Additional sulfur analyses from other areas around the Cienega Creek watershed are needed, including analysis of local sulfur-bearing rock strata.

Tritium and Carbon 14 Isotopes The apparent age of groundwater can be dated using the tritium concentration and radiogenic carbon, δ14C. Eastoe et al. (2004) did a comprehensive analysis of the origins and flow paths of groundwater in the Tucson basin with the study area extending to the region including the Pantano Dam site in Cienega Creek. This analysis included calibration with current precipitation values. Groundwater older than the 1950’s has a TU at or near zero. The 1950’s bomb-pulse tritium decayed overtime, and since 1991 local rain contains 4.7 to 6.7 tritium units (TU). Based on tritium and δ14C analysis near the Pantano dam site, Eastoe et al. (2004) show that some areas along lower Cienega Creek have pre-1950’s groundwater, lacking in both tritium and

Cienega Creek Groundwater Evaluation Page 30

modern carbon, adjacent to downstream recharge areas where waters contain tritium and modern carbon, indicating presence of younger recharge.

Tritium data from the Montgomery and Associates (2009) groundwater wells, springs, and surface waters in the proposed Rosemont Project area have TU ranging from <0.6 (below detection limit) to 5.3 TU. Most well samples analyzed for TU in that study have values below 1.3 TU, indicating dominance of older, pre-bomb pulse recharge. Two of the seven springs included in the Montgomery and Associates analyses have TU between 4.8 and 5.3, indicating dominance of recent/modern recharge, while the Questa Spring, mentioned above, has <0.6 TU, indicating this particular spring is dominated by older, pre-bomb pulse recharge.

Tucci and Mcintosh (2015) have competed preliminary analysis of tritium from additional Davidson Canyon groundwater and springs, and most results have below 2.5 TU, indicating a mix of modern recharge with older, pre-bomb pulse, recharge (TU approaching zero). Deering Spring has a higher value closer to the current average value of local precipitation, showing this water is dominated by modern recharge. In order to date the “older” water components more precisely, analysis of carbon-14 would be needed. Additional samples are being collected for analysis by University of Arizona, Pima County Flood Control District, and others to expand this work to other areas of the Cienega Creek basin.

6.0 Key Findings

• The Cienega Basin is a fragile watershed with shallow water affected by anthropomorphic influences and natural drought. The Upper Basin is more resilient than lower watershed due to deeper aquifer, more sources of recharge and more control of the resources. • The most recent water-level data compiled in 2014-2015 shows varying depth to groundwater, ranging from below 50 feet near the channel corridor of Cienega Creek north of I-10 and south of the “Narrows” and in some areas of Davidson Canyon; near 100 feet north of I-10 and on the Empirita Ranch; near 200 feet in the Sonoita area; 200-300 in the Jay six area near I-10 and the Cochise/Pima County Line; and 300-500 feet in the Vail area near Colossal Cave Road. Some of the designated Shallow Groundwater Areas from 2000 are now deeper than 50 feet, especially south of I-10 on Empirita Ranch.

• Water level fluctuations appeared to vary seasonally due to variable recharge and underflows from changing climate, nearby pumping and diversions. The recent 20-year drought has caused a decline in shallow and deep groundwater in watershed. • Deeper wells show steeper declines over the last 20-30 years. Shallower wells near perennial reaches show less declines but there is still a declining trend. Overall, the lower Basin shows a water level decline of about 0.9-0.95 feet/year (ft/yr) over the last 20-30 years; and the last 10- years it has been about 0.5 ft/yr. Probable stressors are drought and increase pumping in the Vail, J-6 areas and more exempt private wells in the area. The upper Basin appears more resilient to drought and experienced less increased pumping than the lower Basin. The declines in the last 20-30 years range from 0.2-0.3 ft/yr; but in the last 10 years have increased to 0.6 ft/yr, possibly due to increased pumping and drought. • A clear relationship has been established between depth to groundwater and length of perennial flow in the lower basin and to a lesser extent with less data in the upper Basin. More data is needed to explore the upper Basin relationship. • The surface diversion at Pantano Dam at Cienega Creek has impaired the Creek’s ability to re- establish riparian vegetation downstream of the Dam. The shallow aquifer immediately downstream of the dam is highly responsive to recharge and can recover if the upstream diversion ceases. • Several groundwater models have been prepared predicting various declines in groundwater levels and base flows. Notably, the models prepared for the Rosemont Mine EIS predict impacts to the upper watershed and also the lower watershed. However these models fall short in assessing the overall impacts from current and future pumping and other influences such as drought and changing climate. • Water quality is quite good for most water indicators in the Basin. However, TDS is higher in portions of the lower watershed near the tilted beds where gypsum is a portion of the subsurface and it is a dominant Calcium Sulfate water. The Davidson Canyon area also has lower TDS and is typically a calcium bicarbonate water. • Most Davidson Canyon and Cienega Basin wells, springs, and surface water have oxygen and hydrogen isotopic results indicating a mix of summer and winter precipitation, with a dominance of winter recharge and some evidence of evaporation prior to recharge or flow. Davidson Canyon Wash surface water flows generally reflect a more isotopically depleted, possibly winter dominant groundwater source, compared to samples closer to the confluence of Cienega Creek and stream samples in upper Cienega Creek. Some wells in the proposed Rosemont project

area and the Questa Spring, about 2- miles west of proposed mine site, are sourced by isotopically lighter groundwater. One surface water site over 10 miles downstream in Davison Canyon Wash is also depleted in oxygen and hydrogen isotopic results, making it possible that local groundwater sources at these few sites have less interaction with modern precipitation compared to most other sampled sites. • Tritium concentrations in domestic wells, exploration wells, and six springs provided an apparent age of groundwater. Results range from <0.6 to 5.3 TU, indicating most groundwater was likely recharged from a mix of modern recharge (<10 years old) and older pre-bomb pulse recharge (>~60 years old). Many samples have tritium results that are at or near the lowest detection limits, and analysis of carbon-14 is needed to date the “older” water components more precisely. Limited sulfur isotopic results indicate a likely groundwater relationship with sulfate from igneous and sedimentary rock strata, and highly localized groundwater interactions with evaporitic minerals.

7.0 Recommendations

• An upper and lower Cienega Creek three dimensional computer model is needed to predict land use impacts on groundwater for these areas. Earlier models in the lower and upper Basins and models in the San Pedro Basin and upper Santa Cruz Basin south of the Santa Cruz County line may serve as templates to model the proposed land uses and climate conditions.

• Purchase adjacent and nearby properties and water rights where possible to minimize pumping adjacent and near the CCNP. Collaboration with such entities as the Arizona Land and Water Trust is also important to find ways of land acquisition and easements.

• Update land management plans. The Cienega Creek Management Plan and all Ranch Plans within the Cienega Creek Watershed need updating every five to ten years. Because of urban encroachment in the Vail Area, more mining claims and drought conditions, the current 1994 CCNP Management Plan needs revision and updating to emphasize different and additional factors and stressors for 2015. Additional strategies to protect shallow groundwater and in- stream flow need incorporation in the updated Plan.

• Continue water level monitoring efforts at key wells sites with long-term records. Funding and personnel is essential

• Continue to pursue the inholding at Pantano Dam. Currently the stream base flow is being diverted to a Vail Golf course for use on greens. Diversion of the water back across the dam to recharge the shallow aquifer could bring water levels up to potentially provide more riparian habitat

Cienega Creek Groundwater Evaluation Page 33

for over one mile. The shallow aquifer immediately downstream of the dam is highly responsive to recharge and can recover if the upstream diversion ceases.

• Pursue methods to enhance upland recharge of stormwater to stabilize groundwater levels. Non-structural methods mimicking the site hydrology including preserving any natural areas and using small scale berms and check dams in first order tributary channels.

• Initiate a public awareness campaign to educate citizens of the important connection between water and riparian areas and promote more water conservation throughout the Basin. This campaign should target exempt well owners in sensitive shallow groundwater areas of the Basin.

• Continue and expand precipitation, stream flow, spring, and groundwater sample collection and analyses for stable (δ18O, δD) and radioactive isotopes (tritium), plus major ion chemistry (anions, cations, and alkalinity). These tracers evaluate the hydrologic connection between upper elevation precipitation, groundwater and surface water flows. To better constrain groundwater ages and groundwater mixing add analyses of δ14C. Special focus is needed on collecting samples from the higher elevations in the Santa Rita, Empire, and Whetstone Mountains to identify precipitation and groundwater contributions from higher elevations. To better constrain groundwater flow paths, add additional groundwater and springs sample analyses of sulfur stable isotopes (δ34S, δ18O sulfate) and δ13C (from dissolved inorganic carbon), plus carbon stable isotopes on carbonate rocks (e.g. gravels in wash), and sulfur stable isotopes on sulfide and sulfate bearing minerals.

• Continue groundwater level and nearby stream (length and flow) and precipitation monitoring in in the upper and lower Basins. Evaluate areas where data is lacking such as between the Narrows and I-10. Insure funding is available to continue the monitoring effort.

• The State should implement Special Basin Status for this unique area, restricting and offsetting water use with another supply or strict water conservation. Because Cienega Watershed is protected by the State as Outstanding Waters, by Pima County with the CCNP and by the US for LCNCA, ADWR needs to afford the Basin special protection, evaluating discretionary water uses to minimize impacts from additional water withdrawals in the basin.

Found at University of Arizona Library Summary: Thesis presented data and research compiled and analyzed to assess the potential impact of proposed pumping by the Anamax Mining Corp. in the Cienega Creek basin area. Previous investigations were cited, including a comprehensive hydrological investigation completed prior to 1980 by Harshbarger & Associates (1978). Data from 13 pumping tests, conducted in the central basin during the late 1970s for Anamax Mining Corp. were used to establish hydrologic and geologic conditions for the applied models. The author estimated from his lowland model that basin recharge was approximately 10,100 af/yr. Of this total recharge, 45 percent was generated from the Whetstone Mountains, 22 percent from the Santa Rita Mountains, 20 percent from the Empire Mountains, seven percent from the Canelo Hills, and six percent from the Mustang Mountains.

Master’s Thesis submitted to the Department of Hydrology and Water Resources, University of Arizona. Found at University of Arizona Library Summary: This thesis, completed in conjunction with the Cienega Creek Group Thesis Practicum Project, evaluated the configuration of bedrock in lower Cienega Creek basin, and to see how it influenced the movement and occurrence of both groundwater and surface water. The interaction between groundwater and surface water was also examined. The data suggested that a decrease in surface water temperature occurred when a bedrock outcrop or fault was located in the area of the sampling point, possibly because the fault provided a “conduit for the discharge of cooler groundwater to the surface stream.” Ellett concluded that the source of perennial flow in the Cienega Creek Natural Preserve was the overflow of groundwater which was forced to the surface by shallow bedrock outcrops.

Study developed a water budget for the upper Cienega Creek watershed, and to evaluate various water and land management policy options. It was concluded that the basin aquifer was experiencing a net loss of 644 acre-feet per year. It was further concluded that perennial flow in upper Cienega Creek would not be affected by growth in the towns of Sonoita and Elgin since most of the land in the upper basin, and the associated water rights, are owned by BLM.
