EXECUTIVE SUMMARY The North Fork Volunteer Water Quality Monitoring Network (the Network) was initiated in April 2001. Working in partnership with the North Fork River Improvement Association (NFRIA), the goal of the program is to obtain credible water quality information for the North Fork of the Gunnison watershed. This project is run entirely by local volunteers, with the donation of time and services from a variety of educational institutions and State, local, and Federal organizations. This report summarizes the results of water quality monitoring conducted from October 2004 to October of 2007 at nine sites located throughout the North Fork watershed. Water quality monitoring initially assessed field parameters, metals, nutrients and bacteria at all sample site each month. In addition, macroinvertebrate sampling occurred approximately once per year. The water quality data was not collected for compliance or regulatory purposes; rather these data are designed to give background information on water quality conditions in the watershed, help water users understand seasonal and natural variation within the watershed, and provide a basic understanding of how the North Fork River compares to State stream standards. Water quality samples collected by the Network indicated that overall, the North Fork River has moderate to good water quality, given natural inputs that increase concentration of metals and dissolved solids (salts) in the river. Such increases are often a reflection of the natural soils and geology of the North Fork Valley. Sample analysis found elevated concentrations of dissolved arsenic and selenium that often exceeded chronic standards. Dissolved fractions of aluminum, copper, iron and lead had isolated spikes that exceeded standards, but the natural sources of salts provide the North Fork with ample capacity to buffer against change in pH and the toxic effects of metals. Storm events tend to move large amounts of sediment and organic material through the North Fork. The particulate matter transported in the North Fork can be laden with adsorbed metals and nutrients, such as iron and phosphorus. Overall, nutrient concentrations in the North Fork were relatively low. Nitrate concentrations were well below the Maximum Contaminant Level (MCL). Ammonia exceeded the chronic standard once, however all other samples were over an order of magnitude below standards. Biological data indicates that that the North Fork routinely exceeded State E. coli standards during summer months. E. coli standards were exceeded at every active station at least once between 2005 and 2008. Macroinvertebrate monitoring indicates that the North Fork has a thriving and diverse biological community that is sensitive to pollution. If you want more information or would like to participate as a volunteer in the North Fork Water Quality Monitoring Project, please contact us at (970) 872-4614. Thank you for your time, interest and support of the North Fork. We hope you find this report informative.

1. DESCRIPTION OF THE NORTH FORK WATERSHED

1.1. Introduction NFRIA Established in 1996, the North Fork River Improvement Association (NFRIA) is a 501(c)3 non-profit group that NFRIA Mission: empowers a broad-based coalition of riverfront To meet current and landowners, farmers and ranchers, environmentalists, irrigation companies, outdoor recreators, in-stream future demands for gravel mining companies, and concerned members of traditional uses of the community as the driving force behind resource restoration efforts. the river while Originally formed to research alternative methods to improving stream reduce extreme and accelerated bank erosion along the stability, riparian North Fork of the Gunnison River in Colorado, NFRIA habitat, and quickly transformed into an innovative local watershed group aimed at rehabilitating the ecology of the river ecosystem function corridor while working closely with all river interests to along the North develop consensus and collaborative efforts. In 2000 the Watershed Restoration Action Plan was created. Fork of the Hunting, fishing, boating, tourism and scenic enjoyment Gunnison River. are important to the area's quality of life and help create a stronger, more diverse economy. As a valuable community resource, the North Fork of the Gunnison is inseparably linked to the surrounding land and the species that depend upon it. By enhancing and restoring the river, we protect our health, ensure our economic viability, and serve as stewards of our natural world. NFRIA strives to be a model watershed organization, working hard to develop consensus, collaboration and local participation on watershed issues in the North Fork basin. NFRIA’s goals include: • Educate the community on the value of the river's natural resources and their responsible use. • Engage local farmers and ranchers in riparian enhancement and agricultural conservation • Improve water conservation through innovative and sustainable irrigation practice • Encourage the community to build consensus and develop collaborative solutions to complex resource problems • Restore proper riverine function to damaged stretches of the river • Enhance fish and wildlife habitat • Improve and monitor water quality • Disseminate information to the community, government agencies, and other watershed groups on ecosystem protection and conservation

North Fork Volunteer Water Quality Monitoring Network The North Fork Volunteer Water Quality Monitoring Network (the Network) was initiated in April 2001. The goal of the program is to obtain credible water quality information for the North Fork of the Gunnison watershed. This project is run

1-1 NFRIA Volunteer Water Quality Monitoring Data Report, 2009 entirely by local volunteers, with the donation of time and services from a variety of educational institutions and State, local, and Federal organizations. It represents the efforts of dozens of volunteers, and hundreds of hours spent preparing and analyzing samples. This report summarizes the results of water quality monitoring conducted from October 2004 to October of 2007 at nine sites located throughout the North Fork watershed. This volunteer program provides water quality information from above Paonia Reservoir to the confluence with the Gunnison River. The project monitors water quality parameters of concern, including selenium, fecal coliforms, nutrients, sediment, and metals. Data gathered from the Network is provided to U.S. Environmental Protection Agency (EPA), the State of Colorado, Colorado Data Sharing Network and Colorado River Watch for inclusion in their publicly available databases. In the long-run, it is hoped that the information collected by will encourage informed decision-making by local citizens, government agencies, and local officials. The Network is intended to continue indefinitely and supply the people of the North Fork Valley with reliable information about the state of their watershed.

1.2. Watershed Description The North Fork of the Gunnison River (North Fork) is located in west-central Colorado, flowing through northwestern Gunnison and eastern Delta Counties. Flanked by the West Elk mountain range to the east, the peak elevation in the North Fork watershed is 13,687ft. The headwaters of the North Fork are located in the Gunnison National Forest. The North Fork is formed by the confluence of Muddy Creek and Anthracite Creek downstream of Paonia Dam (see Figure 1-1). The North Fork flows 33 miles in a southwesterly direction from this point to its junction with the Gunnison River at 4,553 ft elevation, approximately 8.5 miles west of the Town of Hotchkiss in Delta County. Terror, Hubbard, Minnesota, Rotcap, Cottonwood, and Leroux Creeks enter the North Fork between Paonia Reservoir and Hotchkiss. The North of Fork watershed (HUC 14020004) drains a basin of approximately 986 square miles. Five small communities line the banks of the North Fork as it flows west towards the Gunnison River: Somerset, Bowie, Paonia, Hotchkiss, and Lazear. Figure 1-2 shows the location and topographical relief of the North Fork watershed. The North Fork Valley consists of multiple river terraces positioned laterally along a highly dissected broad valley with gentle down-valley elevation relief. The soils along the river are deep to moderately deep, nearly level to steep, well-drained gravelly loam and stony loam that formed in outwash alluvium derived from igneous rock. The vegetation is classified as northern desert scrub and consists primarily of juniper, sagebrush, western wheatgrass, muttongrass, fourwing saltbush and bitterbrush.

1.3. Point Sources There are sixteen National Pollution Discharge Elimination System (NPDES) permitted discharge facilities in the North Fork watershed. Table 1-1 lists all the permitted dischargers in the North Fork watershed and Figure 1-3 displays the discharge facility locations. There are two permitted wastewater treatment plants (WWTPs) within the watershed: Town of Paonia and Town of Hotchkiss. All other towns, businesses, and private residences in the area utilize independent sewage disposal systems (ISDS).

1.4. Land Use Current land uses in the study area are predominantly agricultural. Of the more than 1,000 parcels adjoining the river, 35 percent are classified as agricultural, consisting of cattle and sheep ranches, crop production, and fruit orchards. Extractive industries include hard rock coal mining, gravel mining, and logging. Tourism and outdoor recreation supplement the general economy. The majority of riverfront property is privately owned and used for agriculture, recreation, and gravel mining.

The land cover in the upper reaches of the watershed, above Somerset, is a mixture of aspen deciduous and coniferous forest. Much of this land is federally owned and managed by the US Forest Service and Bureau of Land Management. Beginning in Paonia and stretching downstream to the confluence with the Gunnison River, the land cover changes to agriculture and shrub/scrub. South West Regional Gap Project land cover data in the North Fork is illustrated in Figure 1-4.

1.5. Flow Data The North Fork of the Gunnison River is a fourth order perennial stream, fed predominantly by snowmelt, with average bankfull widths of 100 to 200 feet. The average bankfull flow during the spring runoff is approximately 3,000 cubic feet per second (cfs); however, irrigation diversions can reduce late summer flows to less than 20 cfs. The predominant alluvial landforms can produce high bedload and sediment concentrations, especially during spring runoff. Average flows are highest during the spring snowmelt runoff months of April and May. Major flooding may also occur during spring runoff months from rapid snowmelt that is sometimes augmented by rain. Snowmelt flooding is characterized by moderate peak flows, large volumes of runoff, and long flow duration. Flooding from rainfall is characterized by high peak flows of moderate duration. The Network does not manually collect flow data. The U.S. Geological Survey (USGS) and Colorado Division of Water Resources (DWR) both manage gaging stations along the North Fork of the Gunnison River and its tributaries. The gages provide real-time flow data that is electronically available. Table 1-2 summarizes the stream flow gauging stations utilized by the NFRIA Network.

1.6. Other Water Quality Monitoring Efforts The North Fork Volunteer Water Quality Monitoring Project, in conjunction with Colorado River Watch, is the only active comprehensive water quality data collection program in the North Fork watershed. The Colorado Department of Public Health and Environment (CDPHE) typically collects samples in the watershed every five years near the Town of Lazear. Historic sampling efforts by agencies such as U.S. Geological Survey, the local mining companies, and the Colorado Division of Wildlife (CDOW) have been of limited duration, or focused on only a specific segment of the watershed. For example, in 1998, the USGS monitored for selenium and other water quality parameters of concern in Leroux Creek and the mainstem of the river, in cooperation with the Gunnison Basin Selenium Task Force. However, the USGS currently has no further plans to monitor these tributaries. For a comprehensive list of all historic data collection efforts, see the 2005 NFRIA volunteer monitoring report.

1.7. Water Quality Pollution Risks Many potential pollution sources exist in the North Fork Watershed, including coal mining operations, gravel mining, cattle and sheep ranches, small-town wastewater treatment discharges, intensive irrigation of numerous crops, the annual bulldozing of in-stream diversion structures, independent sewage disposal systems.

1.8. Water Quality Standards The Colorado Water Quality Control Commission (WQCC) created a regulatory framework called Basic Standards and Methodologies for Surface Water to protect water quality in Colorado. Water quality standards are dependent on current and desired future beneficial uses and are applied on a segment-by-segment basis. The official designated uses for the North Fork include Aquatic Life, Recreation, Water Supply and Agriculture. Table 1-3 shows the stream segments (WBIDs) from Regulation 35 that are sampled by the North Fork Volunteer Water Quality Monitoring Project and the State's applicable water quality standards for those segments. The WBID segments are also displayed in Figure 1-4. Ever two years, CDPHE is required to prepare a list of impaired streams not meeting water quality standards called the 303(d) Impaired Waters List. In 2008, there were four segments on the 303(d) list for Selenium (Se) impairments, as shown in Table 1-4. Figure 1-5 shows the location of impaired segments on the 303(d) list. Selenium is a metal commonly found in the Mancos shale soils present throughout western Colorado. Locally, these soils are called “adobe.” Selenium may be leached from the soil into local water ways when water used for irrigation and other purposes passes through soils derived from Mancos shale. Selenium bioaccumulates in aquatic systems and may eventually cause reproductive problems and deformities in fish and waterfowl. Significant human consumption of fish containing high concentrations of selenium may result in human health problems. A regulatory precursor to the 303(d) list is the Monitoring and Evaluation List (M&E List). This list identifies waters of questionable water quality. The 2008 M&E List identifies two segments that may be impaired by iron (Fe), see Table 1-5. Figure 1-6 shows the location of impaired segments on the M&E list.

2. NORTH FORK VOLUNTEER MONITORING NETWORK

2.1. Introductions Since April 2001, Network volunteers have been collecting water samples in the North Fork Valley. As part of this joint project, coordinated by North Fork River Improvement Association (NFRIA) and Colorado River Watch, volunteers receive lab and field training on EPA-approved water sampling procedures. Volunteers travel once a month to seven different sites throughout the watershed to collect samples. The sample stations start as high up as East Muddy Creek, proceed down the North Fork of the Gunnison and extend as far as the confluence with the main stem of the Gunnison River. Samples are collected for analysis of temperature, dissolved oxygen, alkalinity, hardness, pH, metals, nutrients, and bacteria. The majority of samples collected and analyzed by the Network are done in conjunction with Colorado River Watch (River Watch). River Watch is a state wide volunteer monitoring program that focuses on collecting baseline water quality data. River Watch provides volunteer groups like NFRIA with training, water monitoring equipment, chemicals for analysis of field parameters and lab analysis for metals and nutrients. All River Watch data is publicly available on the River Watch website: http://wildlife.state.co.us/riverwatch/. The Network bacteria monitoring program commenced in 2001 in partnership with the Environmental Protection Agency (EPA) after water quality standards in segments in the North Fork were upgraded to reflect recreational uses1. Bacteria samples are not collected for regulatory or compliance purposes. Rather, data (total coliforms and E. Coli) provides a screening-level assessment of bacterial concentrations. The following sections explain the specifics of the Network’s water sampling program, including the location of the water quality monitoring stations, parameters analyzed, and the volunteer training program.

2.2. Water Quality Monitoring Stations The North Fork Volunteer Monitoring Network has data on ten stations throughout the North Fork watershed and two stations in the Lower Gunnison watershed. Table 2-1 outlines the location, description and active period for each station. The stations are strategically located to provide baseline coverage of the watershed stretching from the headwaters to the mouth. Monitoring locations and frequencies have changed over the years to reflect changing priorities. Figure 1-1 shows a map of all active Network monitoring stations.

1 Segment 2 was upgraded to a Recreation Class 1a stream and Segment 3 was changed to a seasonal based standard.

2.3. Water Quality Parameters Monitored The Network’s water quality monitoring program collects information on the chemistry, biology, and physical habitat of the North Fork River. During the October 2004 to October 2007 sample period, Network volunteers collected monthly field, metals, nutrient samples and bacteria. Macroinvertebrate/physical habitat analyses were conducted annually. Table 2-2 lists the water quality parameters the Network monitors and Table 2-3 provides a brief description of each parameter. The results of the water quality monitoring program are summarized in Sections 3 through 8.

Table 2-3 Parameters monitored by the Network

Parameter Description/Relationships Field Parameters pH Measure of hydrogen ion (H+) concentration. Water with a pH below 7.0 is acidic; a pH above 7.0 is alkaline. Temperature Varies seasonally, fish and aquatic life require specific temperatures to reproduce and thrive.

Total Alkalinity, as CaCO3 Measure of carbonate (HCO3-) and bicarbonate (CO3-) anions present. Reflects the river's buffering capacity

Total Hardness, as CaCO3 Measure of mineral cations (Ca2+, Mg2+, Na+). Mitigates metals toxicity for fish. Dissolved Oxygen Amount of oxygen in the water in its dissolved form. DO varies with temperature and flow and is indirectly related to temperature. Nutrients Total suspended solids Minerals and soil particles suspended in the water column. In slow or low flows, this material can be deposited in the streambed.

Sulfates This form of sulfur (SO4) is most common in the oxidizing conditions of flowing waters. Chlorides Can originate from natural sources, but commonly associated with evaporation, road salts or water treatment plants. Total phosphorus Common constituent in soil and some fertilizers. N, Nitrate-nitrite Nitrates and nitrites are oxidized forms of nitrogen commonly found in flowing water. N, ammonia Ammonia is a common component of organic wastes (e.g., sewage). Can be toxic to fish in high concentrations. Bacteria Total Coliform A family of microorganisms that originate in the intestines of humans and other warm-blooded animals. Not always pathogenic (disease causing), although high levels may indicate risk. Escherichia Coli (E. Coli) Bacteria associated with water-borne diseases such as dysentery and cholera. Many E. Coli bacteria cause no health problems, others may be highly pathogenic. Metals Aluminum Most abundant naturally occurring metal in the earth’s surface Arsenic Naturally occurring element in the earth's crust and mineral deposits. May enter the soil from natural or manmade sources. Cadmium Naturally occurring, the largest source of cadmium is often burning of fossil fuels and incineration of municipal waste. Calcium The most abundant cation in the world’s rivers and a common constituent of local soils. Important contributor to hardness. Copper Found in mineralized ore deposits. Rarely found in pristine source water, may reflect mining impacts. Iron Second most abundant metallic element in earth's crust. Excessive amounts may cause staining of plumbing fixtures and laundry. Lead Highly toxic, can accumulate in fish and human tissue with negative health effects. Magnesium A major component to hardness and is primarily derived from the weathering of rocks Manganese Essential element in plant and animal metabolism. Elevated manganese in water systems. Selenium A naturally occurring metal common in the Mancos shale. Leaches from soils via irrigation and toxic to fish and wildlife. Zinc Zinc is relatively abundant, but may be released to the environment by coal burning, mining, and other industrial activities. Macroinvertebrates The presence of a diverse range of macroinvertebrate species serve as “bioindicators” and is a sign of adequate habitat and a healthy river ecosystem. The presence of certain sensitive species is a good sign.

2.5. Sample Collection and Analytical Procedures The majority of Network samples are collected using the grab sample technique. Grab samples entail volunteers wading into the stream and collecting water using a large bucket. Water from this bucket is used to fill all subsequent sample bottles. When river water levels permit, volunteers may collect composite samples. Composite samples are collected at multiple locations moving across a stream channel. Sampling and analysis procedures utilized by the Network follow Standard Methods and/or EPA approved methods. Table 2-4 lists the sample method code and laboratory reporting limits for each parameter monitored.

2.6. Volunteer Training and Certification All volunteers must attend a River Watch training workshop before they can join the Network. The River Watch training provides in-depth instruction on all aspects of water monitoring: sample preparation, collection, analyses, shipping, data management and Quality Assurance & Quality Control (QA/QC) procedures.

2-5 NFRIA Volunteer Water Quality Monitoring Data Report, 2009

The NFRIA Technical Advisor accompanies volunteers on the first several sampling runs until satisfied that the volunteers can complete the sampling procedures independently. Volunteers between the ages of 10 and 18 can be trained and work alongside at least one adult in the field and lab. Figure 2-2 shows Network volunteers collecting samples from the North Fork and processing them in the CSU Rogers Mesa Research Laboratory.

Figure 2-2 Volunteers collecting and processing water quality samples

2.7. Quality Control/Quality Assurance Measures Quality control measures both in the field and in the lab are detailed in Quality Assurance Project Plans (QAPPs) developed by Karla Brown in 2001. For this project three separate QAPPs were created, one each for nutrients, bacteria, and metals. The QAPP documents are available for inspection at the NFRIA office in Hotchkiss. As part of the River Watch program, the Network participates in a rigorous annual QA/QC regime. Network QA/QC controls include twenty percent duplicate and blank samples, analysis of unknown samples twice per year and an annual site visit from a River Watch staff member. The QA/QC measures evaluate techniques, chemicals and equipment. Chains-of-custody forms accompany all shipped samples.

2.8. Data Reporting Volunteers use standardized reporting forms developed by River Watch for every sample collection event. Hard copies documenting sample location, date, time, field conditions and field parameters are stored at the CSU Rogers Mesa Lab and the River Watch office in Denver. Information from the data sheets is validated and then entered into the online River Watch database (except for bacteria), where it is eventually combined with metals and nutrient results. The River Watch data are publicly available online at: http://wildlife.state.co.us/riverwatch/. River Watch data are also uploaded to the Colorado Data Sharing Network (www.codsnstoret.com) and EPA’s STORET (www.epa.gov/storet).

2.9. Project Sponsors The North Fork Volunteer Water Quality Monitoring Project would not be possible without the support of many different State, Federal, and local organizations. Each group provides critical support, either in the form of technical assistance, lab equipment, or volunteer recruitment. The following is a list of the project partners: • North Fork River Improvement Association (NFRIA) is responsible for water quality data management, volunteer recruitment and training, report creation, and technical support to the project. In addition, NFRIA advertises the project to

2-6 NFRIA Volunteer Water Quality Monitoring Data Report, 2009

the local community, initiates fundraising efforts, and assists with map and report creation efforts. • River Watch Program, co-sponsored by the Colorado Watershed Assembly and the Colorado Division of Wildlife was instrumental for the start-up of this program. The Colorado Watershed Assembly helps supply critical training, technical support, equipment, and encouragement to get activities started. They also help link this project with the numerous other volunteer water monitoring projects throughout the State. (Thanks Barb Horn, Michaela Taylor, Matt McIntyre and Curtis Hartenstine). • U.S. Environmental Protection Agency Region 8 provides all bacteriological sample analysis for this project, as well as significant technical assistance. They provide crucial high quality data for this key parameter of concern in the North Fork watershed. • CSU Cooperative Extension was also instrumental in initiating the network. They provide use of laboratory space at the Roger's Mesa Research Station in Hotchkiss, Colorado. • Colorado Division of Wildlife Aquatic Biologist Barb Horn conducts annual site visits and provides technical advice. • Jim Link, owner of Paonia Farm and Home provides donation to help with shipping costs. • Hardin’s Natural Foods provides snacks to volunteers every month. • Walcott Family Foundation provided a grant to support the development of this water quality report.

3. FIELD DATA NFRIA field parameters consist of those sampled and analyzed “in house” by the Network. Field parameters include: total hardness, total alkalinity, phenolphthalein alkalinity, pH, temperature and dissolved oxygen. Samples are collected and analyzed by project volunteers in a laboratory at the Colorado State University (CSU) Roger’s Mesa Agricultural Experiment Station in Hotchkiss. The following section summarizes the results from October 2004 to October 2007. Many of the graphs in the sub-sections below illustrate values from selected stations. A complete water quality dataset can be found in the Appendix. Please refer to Figure 1-2 for a map of all water quality monitoring stations.

3.1. Hardness Hardness is a measure of the most prevalent polyvalent cations (ions with a positive charge greater than +1) in water: calcium (Ca2+) and magnesium (Mg2+). Hardness is measured in mg/L of calcium carbonate (CaCO3). The ions contributing to the hardness of water are often derived from the drainage of calcareous (calcite-rich) sediments such as limestone, dolomite or gypsum. The dissolution of calcium, magnesium and other polyvalent cations, such as iron and manganese, from rocks and soils can also contribute to hardness in natural systems. Mine drainage, certain industrial processes, sewage outflow and irrigation can artificially increase hardness in waterways. Waters with high hardness values are referred to as "hard," while those with low hardness values are "soft". Table 3-1 outlines EPA hardness ranges. Hard water can prevent soap from producing lather, leaves behind undesirable films or scum on hair, fabrics and glassware, and can form scale when used in boilers and water heaters. Water softeners can make hard water functional for household purposes by replacing calcium (Ca2+) and magnesium (Mg2+) with sodium (Na+) and potassium (K+) ions. Table 3-1 EPA Hardness Ranges

Hardness Level Concentration (mg/L CaCO3) Soft 0-75 Moderate 75-150 Hard 150-300 Very Hard 300+ Hardness is advantageous in aquatic systems because it can mitigate the toxic effects of metals. While the exact mechanism is unknown, Ca2+, Mg2+ and other polyvalent cations prevent fish from absorbing metals such as lead, arsenic and cadmium into their bloodstream through their gills. The greater the hardness, the more difficult it is for toxic metals to be absorbed through the gills. Therefore, hardness is inversely related to metals toxicity. Figure 3-1 shows hardness data from October 2004 to October 2007 at selected stations along the North Fork. Overall, stations in the upper reaches of the watershed (EM-1 and NF-1) exhibit hardness values in the “soft: to “moderate” hardness range. Station EM-1 occasionally peaks in the “hard” range. Lower stations (NF-3a and NF-4a) generally have higher hardness values that fluctuate between “moderate” to “very hard”. The high hardness values at the lower stations may be due to the influences of irrigated agriculture and/or higher concentrations of calcium and magnesium in the soils affecting the lower reaches of the watershed.

3-1 NFRIA Volunteer Water Quality Monitoring Data Report, 2009

Seasonal fluctuations can also be observed in total hardness concentrations. Figure 3-1 shows pronounced spikes and dips in total hardness at the lower stations. Peak hardness concentrations occurred between the months of July and August. These mid-summer spikes can likely be attributed to irrigation. The lowest hardness concentrations at the lower stations occurred between March and June. The low spring hardness values are likely due to the dilution of calcium and magnesium in the river due to snowmelt during spring runoff.

Figure 3-1 Total Hardness Values in the North Fork

3.2. Alkalinity Alkalinity is a measure of buffering capacity, or the ability of water to resist change in pH when an acid or base is added. It represents the balance of carbon dioxide in water and is reported as mg/L CaCO3, but is actually a measure of the amount of - 2- HCO3 (bicarbonates) and CO3 (carbonates) anions that are present. The presence of buffering materials, carbonates, bicarbonates, and occasionally hydroxide (OH-), help neutralize acids as they are added to water. Moderate levels of alkalinity are desirable in aquatic systems because it can limit, or buffer, the effects of acid mine drainage or acid rain. Waters with low alkalinity (below 10 mg/L) are poorly buffered and very susceptible to changes in pH. Systems with alkalinity concentrations above 100 mg/L are able to resist major shifts in pH. Alkalinity typically increases downstream as the geology changes from igneous rocks and carbonate-poor soils in the headwaters to limestone, sedimentary rock and carbonate-rich soils in lower portions of a watershed. Alkalinity is also beneficial because it can mitigate the toxic impacts of dissolved metals. Carbonate and bicarbonate ions bind with dissolved metals such as lead, arsenic and cadmium, causing them to precipitate out of solution and become unavailable for aquatic life.

3-2 NFRIA Volunteer Water Quality Monitoring Data Report, 2009

Figure 3-2 illustrates total alkalinity values from selected stations in the North Fork from October 2004 to October 2007. Like hardness, alkalinity is inversely related to flow. Peak concentrations in the lower stations occurred during low flow conditions between June and August and dips in alkalinity occurred between April and June during peak flow conditions. Alkalinity at the lower stations and EM-1 is generally adequate to buffer against changes in pH. However, during peak flow conditions alkalinity concentrations dropped below the 100 mg CaCO3/L benchmark. Buffering capacity in the upper stations appears to be limited, as illustrated in Figure 3-2. Alkalinity at station NF-2 reached the level needed to stabilize pH three times, each during low flow conditions: 102 mg CaCO3/L in March 2005, 108 mg CaCO3/L in September 2006 and 104 mg CaCO3/L in January 2007. The highest recorded alkalinity concentration at NF-1 is 98 mg CaCO3/L, January 2007. There are no recorded instances of “poor” buffering capacity (below 10 mg CaCO3/L). The lowest reported alkalinity concentrations occurred at station NF-1: 20 mg/L in July, 2005 and 18 mg/L in August 2006.

3.3. pH pH measures the acidity of a solution. It is determined by the relative concentration of hydrogen (H+) and hydroxide (OH-) ions. The pH scale is negatively logarithmic and ranges from 0 to 14. Solutions with low pH values, below 7, are acidic and have more H+ than OH-. Basic solutions have high pH values, above 7, and have more OH- than H+. A neutral solution has a pH of 7 and equal concentrations of H+ and OH-. Aquatic ecosystems have adapted to tolerate a narrow range of pH, but most prefer pH values between 6.5 and 8.0. If the pH becomes too high or too low it can lead to problems in reproduction and even death.

3-3 NFRIA Volunteer Water Quality Monitoring Data Report, 2009 pH can also influence the state of metals in water. Low pH levels can liberate toxic metals from rocks or sediments in a stream, which can affect fish metabolism and lead to death in fish fry. The Water Quality Control Commission (WQCC) has set a standard of 6.5 to 9 for pH in natural waters. There is also secondary drinking water standard of 8.5, which is particularly relevant to station NF-1 because it is just upstream of the intake for the Town of Somerset’s drinking water. Figure 3-3 displays the pH values of the Network volunteer monitoring program from select stations from October 2004 to October 2007. The pH of the North Fork is slightly basic. The majority of pH values are between 8.0 and 8.5. Peak pH values occurred at station EM-1 (8.85 and 8.65) and NF-2 (8.80). The lowest recorded pH value was 7.0 at station NF-1 in December 2005. All pH values are within the state’s allowed range. (6.5 – 9.0). pH at station NF-1 only reached the secondary drinking water standard of 8.5 one time: August 8, 2007.

3.4. Dissolved Oxygen and Temperature

Dissolved oxygen (DO) is the amount of oxygen (O2) dissolved in water. It is an important indicator of a water body’s ability to support life because most aquatic organisms require oxygen to breathe. The WQCC standard for DO is 6.0 mg/L. Figure 3-4 shows that DO rarely drops below the State standard. Station EM-1 dropped to 5.6 mg/L on April 13, 2005 and NF-4a dropped to 5.9 mg/L on August 10, 2005. Low DO levels are common in late summer/early fall due to high temperatures and macrophyte senescence. The low DO levels at EM-1 are unexpected because of the location high in the watershed. Water becomes oxygenated directly from the atmosphere and by photosynthesis of aquatic plants and algae. Oxygen is removed from the water by respiration and decomposition of organic matter. Dissolved oxygen levels vary with water temperature, altitude, depth and flow. Dissolved oxygen concentrations typically

3-4 NFRIA Volunteer Water Quality Monitoring Data Report, 2009 exhibit diurnal patterns due to cycles of photosynthesis/respiration. Seasonal trends also occur because of the relationship between oxygen and temperature. Cold water has the ability to hold more oxygen. As a general rule, dissolved oxygen is inversely related to temperature. The dissolved oxygen and temperature relationship at station NF-3a is illustrated in Figure 3-5.

In addition to influencing how much oxygen water can hold, temperature affects the rate of metabolic and reproductive activities. Most aquatic organisms are “cold-blooded,” which means they are unable to control their body temperature. Cold-blooded organisms are adapted to specific temperature ranges. In 2007, the WQCC instituted temperature standards for the Gunnison Basin. The stream segments monitored by the Network’s volunteer monitoring program are classified as Aquatic Life Cold 1, which means they are subject to a chronic temperature standard of 20 degrees C (Maximum Weekly Average Temperature). According to Regulation 35, “Temperature shall maintain a normal pattern of diurnal and seasonal fluctuations with no abrupt changes and shall have no increase in temperature of a magnitude, rate, and duration deemed deleterious to the resident aquatic life.” Figure 3-6 shows reported monthly temperatures in the North Fork from October 2004 to October 2007. Station NF-5, the furthest downstream, typically exhibited the warmest water temperature. The upper stations (EM-1, NF-1 and NF-2) had the coolest temperatures. The temperature reached 20 degrees Celsius in the North Fork on four occasions: NF-5 (June 2005 and June 2006), NF-3a (July 2006), and NF-3a (August 2006). It is important to note that the volunteer program typically collects samples in the morning and that the reported values to not represent the maximum weekly average temperature (MWAT) from which the chronic standard is applied.

4. NUTRIENT DATA

Network nutrient parameters are collected by Network volunteers and analyzed by River Watch staff at the Division of Wildlife laboratory in Ft. Collins. Nutrient parameters include nitrate-nitrite, ammonia, sulfate, total phosphorus, chlorides and total suspended solids. The following section summarizes the results from October 2004 to October 2007. Many of the graphs represent data from select stations. The complete nutrient dataset can be found in the Appendix. Refer to the map in Figure 1-1 for station locations.

4.1. Sulfur (sulfates) Sulfate concentrations in the North Fork may be influenced by the hot sulfur springs that bring sulfate-laden ground water to the surface. In aquatic systems, sulfate levels are dependent on the geochemistry of the soils and rocks that water comes in contact with. Common sources of sulfur include gypsum (CaSO4) which contains sulfate, and pyrite (FeS2), which contains sulfide. Atmospheric deposition from the combustion of sulfur-containing fuels by cars and industrial operations can also contribute sulfur to aquatic systems. In small amounts, sulfur is important to aquatic life. Cells require sulfur to metabolize protein compounds responsible for energy transformations. Excessive amounts of sulfur in the water, however, can be toxic. When combined with metals, sulfur reacts with dissolved oxygen to create sulfate ions and sulfuric acid, which causes the water to become more acidic.

4-1 NFRIA Volunteer Water Quality Monitoring Data Report, 2009

Sulfate concentrations from selected stations are shown in Figure 4-1. Like the alkalinity and hardness trends, sulfate concentrations increase downstream. Sulfate is considerably higher at lower stations (NF-4a and NF-3a) than upper stations (EM-1 and NF-1). This may be due to the influence of the sulfur springs in the mid-valley. Figure 4-1 also shows that sulfate concentrations drop in the spring and peak in the late summer. This suggests that sulfate is diluted by spring runoff, but concentrated by irrigation laden base flows influenced by soils and geological formations. Sulfate has a secondary drinking water standard of 250 mg/L because sulfate has an undesirable taste. Secondary drinking water standards are not enforceable, but are intended as guidelines to maintain aesthetic qualities relating to public acceptance of drinking water. Downstream sulfate concentrations regularly exceed the 250 mg/L standard. This is not a significant water quality concern because the lower North Fork is not used as a drinking water supply.

4.2. Total Suspended Solids (TSS) Total Suspended Solids (TSS) are the solids in water that are kept in suspension by turbulence in the water column. TSS can include mineral materials, sediment, decaying plant and animal matter, bacteria and waste material that a river transports. High concentrations of suspended solids can cause many problems for stream health and aquatic life. Suspended materials can clog fish and insect gills, smother spawning beds, impair sight dependent predation, trap sunlight, increase water temperature and possibly lower dissolved oxygen levels. There are currently no water quality standards for TSS, although most people consider water with a TSS concentration less than 20 mg/L to be clear. Water with TSS levels between 40 and 80 mg/L tends to appear cloudy, while water with concentrations over 150 mg/L usually appears dirty2. The nature of the particles that comprise the suspended solids may cause these numbers to vary. Figure 4-2 shows selected TSS concentrations in the North Fork from October 2004 to October 2007. The TSS concentrations at all stations experienced periods of relatively clear conditions and periods of cloudy to extremely dirty conditions. The highest recorded TSS concentration was 488.8 mg/L at station NF-5 on March 14, 2007. Overall, station EM-1 exhibited the highest TSS concentrations, which likely reflects geological conditions in Muddy Creek’s headwaters. Stream discharge is a primary factor in TSS concentrations. Fast moving water can transport more particles and larger-sized sediment. As water slows, it loses its holding capacity and deposits the suspended sediments at the bottom of a stream or lake bottom. Figure 4-3 shows the relationship between TSS and flow at station NF- 1. The relationship between TSS and flow is not statistically significant, but in general increases in TSS correlate to increases in flow. This relationship is opposite of that with flow and hardness, alkalinity and sulfur; high flow events increase TSS concentrations rather than dilute them. Spikes in TSS correlate to peak flow conditions for nearly all sampling events.

4.3. Phosphorous Phosphorus is a nutrient required by all organisms for the basic processes of life. It is a naturally occurring element found in rocks, soils and organic material. In comparison to the rich supply of the other major nutrients required for metabolism of aquatic life (carbon, nitrogen, oxygen and sulfur), phosphorus is the least abundant and most commonly limits biological productivity. Phosphorus is often referred to as a limiting nutrient in most freshwater systems. Phosphorus binds tightly to soil particles, metal oxides and hydroxides under aerobic conditions. In clean waters, phosphorous concentrations are typically very low. However, phosphorus is used extensively in fertilizers and concentrated in sewage, so it can be found in high concentrations near human activity. The most significant 3- form of phosphorus is dissolved inorganic phosphorus, or orthophosphate (PO4 ). However, over 90% of the phosphorus in freshwater systems occurs as organic phosphates; cellular constituents in biota that are often adsorbed to inorganic particles3. Total Phosphorus (TP) is a measure of all phosphorus constituents in aquatic systems. Total Phosphorus (TP) 0.0008 EM-1 NF-1 NF-3a NF-4a 0.0006

Figure 4-4 Total Phosphorus (TP) in the North Fork There are no national or state criteria for phosphorous concentrations in water. However, to control eutrophication (excessive biological activity due to inputs of nutrients), EPA has developed recommendations: total phosphate (as phosphorus) should not exceed 0.1 mg/L in streams that do not discharge directly into lakes or

4-4 NFRIA Volunteer Water Quality Monitoring Data Report, 2009 reservoirs4. As shown in Figure 4-4, total phosphorus concentrations are well below the EPA recommendation. Figure 4-4 also illustrates the seasonal differences in TP concentrations. TP concentrations increase in the spring during snowmelt/spring runoff and decrease during low flow conditions in the late summer/fall. This relationship indicates that external landscape contributions are the primary sources of phosphorus in the North Fork. Figure 4-5 shows the peak annual TP loads in the North Fork. Downstream total phosphorus loads (NF-3a and NF-4a) are nearly double upstream (EM-1 and NF-1) loads. Total phosphorus loads typically increase downstream as more and more land drains into the stream. Peak Annual Total Phosphorus Loads 4 May 2005 April 2006 3.5 April 2007

4.4. Phosphorous and Total Suspended Solids As mentioned above, a great deal of the phosphorus in freshwater systems is adsorbed to soils. Total Phosphorus (TP) loads can often times be correlated to increases in Total Suspended Solids (TSS). Figure 4-6 shows the TP and TSS loads at station NF-4a. TSS and TP loads both spike each spring at the same time. This suggests that a large portion of the phosphorus is attached to sediment that is washed off the landscape at spring runoff.

4.5. Nitrogen (Nitrate + Nitrite as Nitrogen) Nitrogen is one of the most abundant elements on earth. Gaseous nitrogen comprises about 80% of the air we breathe. Nitrogen is found in cells of all living things and is a major component of proteins. Inorganic nitrogen may exist in the - - + free state as a gas N2, or as nitrate NO3 , nitrite NO2 , or ammonia NH3 . Nitrogen-containing compounds act as nutrients in streams and rivers. High levels, nitrate along with phosphate, can overstimulate the growth of aquatic plants and algae, resulting in high dissolved oxygen consumption, causing death of fish and other aquatic organisms. This process is known as eutrophication. At high enough concentrations, nitrite can limit the ability of red blood cells to transport oxygen. In fish, this condition is known as “brown blood disease,” and in humans it is called methemoglobinemia, or "blue baby" disease. The EPA regulates nitrates and nitrites under the Safe Drinking Water Act. The enforceable standard, called Maximum Contaminant Level (MCL), for nitrate is 10 mg/L and 1 mg/L for nitrite. River Watch reports nitrate and nitrogen together. The nitrate + nitrite concentrations from select stations are shown in Figure 4-7. The highest reported nitrate + nitrite concentrations were 0.389 mg/L at station TC-1 on December 12, 2006 and 0.381 mg/L at station NF-4a on January 12, 2005. These values are well below MCL levels for both forms of nitrogen. Nitrate + nitrite concentrations in the North Fork were highly variable. In general, concentrations spiked during the winter. The elevated concentrations during winter baseflow conditions suggest that nitrate + nitrite is present in groundwater. Nitrate and nitrite are both very soluble and do not bind to soils, so they have a high

4-6 NFRIA Volunteer Water Quality Monitoring Data Report, 2009 potential to migrate through ground water. In natural waters, most nitrogenous materials tend to be converted to nitrate. Therefore, all sources of nitrogen, particularly organic nitrogen and ammonia, can be considered a nitrate source. In general, major sources of organic nitrates in water bodies include human sewage and livestock manure. Elevated winter nitrate concentrations in the North Fork may be due cattle concentrating along the river corridors. Fertilizers can also be a significant source of nitrate.

Winter nitrate + nitrite loads appear to increase moving down stream. The highest nitrate +nitrite loads occur at station NF-4a. Station NF-4a is located just below the confluence of Leroux Creek and the North Fork. The Leroux Creek drainage, outlined in Figure 4-9, frequently influences the water quality at station NF-4a. There is a high density of irrigated agriculture in the Leroux Creek drainage, and runoff from fertilizer applications may be contributing to the nitrate loads. Other sources of nitrate detected at station NF-4a may be cattle, septic systems and waste water treatment effluent from the Town of Hotchkiss.

4.6. Nitrogen (Ammonia) Ammonia is a form of inorganic nitrogen. The least stable form of nitrogen in water, ammonia is easily transformed to nitrate or nitrogen gas. Ammonia is found in water + in two forms: the ammonium ion (NH4 ) and the dissolved, unionized (no electrical charge) ammonia gas (NH3). Total ammonia is the sum of ammonium and unionized ammonia. The dominant form depends on the pH and temperature of the water.

NH3 is the principal form of toxic ammonia. Exposure to high concentrations of ammonia in humans can cause loss of equilibrium, convulsions, coma, and death. Ammonia concentrations can affect hatching and growth rates of fish; changes in tissues of gills, liver, and kidneys may occur during structural development. The State of Colorado has developed chronic and acute table value standards for ammonia based on temperature and pH. The chronic standard was exceeded one time between October 2004 and October 2007; station NF-5 on December 18, 2004 (2.75 mg/L). In most instances, ammonia values were an order of magnitude lower than the chronic standard. Figure 4-10 shows ammonia concentrations from representative stations in the North Fork. Unlike nitrate + nitrite, ammonia concentrations do not show any obvious seasonal trends. The largest spikes in ammonia concentrations occurred in November 2005 and November 2006. Increases in ammonia concentrations were also observed during spring runoff. In the late summer, ammonia concentrations were at or below River Watch laboratory reporting limits.

5. METALS DATA Network metals parameters are collected by Network volunteers and analyzed by River Watch staff at the Division of Wildlife laboratory in Ft. Collins. Metals parameters include aluminum, arsenic, cadmium, calcium, copper, iron, manganese, lead, magnesium, selenium and total zinc. The following metals results include samples collected from October 2004 through October 2007. The results provide general information regarding basic performance against state metals standards, as well as information on seasonal variation and other background research. The line graphs illustrate seasonal trends and concentrations in relation to state standards. Values that are below laboratory reporting limit are displayed as one half the reporting limits. Bar graphs represent pollutant loads from stations EM-1, NF-1, NF- 3a and NF-4a. Load calculations are based on concentration and flow measurements. Reported as Lbs/day, loads make it possible to evaluate relative contributions from individual pollutant sources. Many of the graphs represent data from select stations. The complete metals dataset can be found in the Appendix. Refer to the map in Figure 1-2 for station locations. Standards in this section were calculated using State of Colorado classifications and numeric standards for the North Fork of the Gunnison River5. Copper, cadmium, lead, and zinc standard calculations are based on hardness values at the time the metals were collected. Aquatic Life standards are generally applied to the dissolved metals because dissolved metals provide a better representation of the biologically available fraction of a metal than total metals which may be attached to or part of sediment. The formulas used to determine numeric standards are: Acute = (1.136672-[ln(hardness) x (0.041838)] )x e0.9151[ln(hardness)]-3.1485 Chronic = (1.101672-[ln(hardness) x(0.041838)] x e0.7998[ln(hardness)]-4.4451 Equation 5-1.

5 This report identifies instances when discrete water samples exceed state water quality standards, as determined by the WQCC. For regulatory purposes, the state applies the 85th percentile methodology when determining if segments violate water quality standards. The 85th percentile methodology allows for 15 percent of the data for a given segment to exceed standards without being in violation of water quality standards. See the WQCC Basic Standards Methodologies for Surface Water (Regulation No. 31) for more information.

5.1. Aluminum Aluminum (Al) is the most abundant naturally occurring metal in the earth’s surface and comprises, on average, about eight percent of the earth’s crust. Geologic formations are, therefore, common sources of aluminum in aquatic systems. In humans, aluminum been shown to be neurotoxic if it enters the bloodstream. Aluminum toxicity can cause encephalopathy (defect of the brain) and/or bone mineralization disorders. Aluminum toxicity is driven by pH. At low pH levels, aluminum toxicity has been documented in invertebrates, fish and amphibian larvae. Aluminum can interfere with cation exchange, electrolyte balance, calcium absorption and respiration in aquatic life. Aluminum is also reported to cause fragile eggs in birds. Colorado has developed chronic (87 ug/L) and acute (750 ug/L) water quality standards for aquatic life. The standards are for total recoverable aluminum, but River Watch only reports dissolved aluminum. A 1993 EPA report6 states that dissolved metals are a better representation of the biologically available fraction of a metal and should therefore be used in aquatic life criteria and state standards. The State of New Mexico has instituted the same numeric benchmarks as Colorado, but in the dissolved fraction. For purposes of this report, Figure 5-1 illustrates dissolved aluminum and dissolved aquatic life standards. Note that the Y-axis is a logarithmic scale. Dissolved Aluminum 10000

5-12 NFRIA Volunteer Water Quality Monitoring Data Report, 2009

Dissolved aluminum concentrations in the North Fork rarely exceeded the acute standard and only occasionally exceeded the chronic standard. With the exception of NF-1 in September 2007, the exceedances only occurred during spring runoff (May/June 2005 and March 2007). The May 11, 2005 sample event captured an extreme runoff event and the dissolved aluminum concentration jumped to over 100 times the recorded April 2005 concentration. The discharge at all stations on May 11, 2005 was nearly double that of the next highest flow events (June 8, 2005 and May 12, 2006). Figure 5-1 shows that high aluminum concentrations are characteristic of spring snowmelts/runoff periods. Spring snowmelt, naturally acidic, can liberate naturally- occurring aluminum from geologic sources into stream systems. The fact that high dissolved aluminum concentrations were detected during the spring, as opposed to concentrations below detection limits during the summer and fall, are indicative of landscape sources.

5.2. Arsenic Arsenic is a naturally occurring element in rocks, soils and the water in contact with them. The toxic effects of arsenic have been recognized for centuries and in 1975 EPA established a standard of 50 ug/L based on a 1942 Public Health Service standard. Scientists subsequently determined arsenic is a carcinogen and in 2001 EPA lowered the maximum contaminant level (MCL) allowed for arsenic in drinking water to 10 ug/L. Colorado has developed Numeric Standards for dissolved arsenic concentrations. The total recoverable standards are listed in Table 5-1. In the North Fork watershed, the arsenic standards vary by WBID segment (See Figure 1-5 for a map of WBID segments). This is in part because of the different designated uses in each segment (Refer to Table 1-5 for a list of designated uses by segment). Table 5-1 Numeric Standards for Arsenic in the North Fork and Lower Gunnison Basins Station Segment Chronic Standard Acute Standard EM-1 COGUNF04 0.02 ug/L (Trec) 340 ug/L NF-1 COGUNF02 0.02 ug/L (Trec) 340 ug/L NF-2 COGUNF02 0.02 ug/L (Trec) 340 ug/L NF-3 COGUNF03 7.6 ug/L (Trec) 340 ug/L NF-3a COGUNF03 7.6 ug/L (Trec) 340 ug/L NF-4a COGUNF03 7.6 ug/L (Trec) 340 ug/L TC-1 COGUNF06a 100 ug/L (Trec) 340 ug/L SC-1 COGUNF06a 100 ug/L (Trec) 340 ug/L Dissolved arsenic concentrations did not exceed River Watch laboratory reporting limits (15 ug/L) until 2007 when six out of nine stations exceeded the state’s chronic standard. Figure 5-2 displays the 2007 exceedances of the chronic standard for dissolved arsenic. The chronic arsenic standard at EM-1 is 0.02 ug/L. This standard was exceeded four times by an average of 29.5 ug/L. Chronic arsenic standards at the remaining stations are significantly higher, yet the standard was exceeded multiple times at the upper stations. The highest reported dissolved arsenic values were 131 ug/L and 116 ug/L at station NF-3. Despite the detected arsenic exceedances, nearly a quarter of the reported dissolved arsenic values in 2007 were

5-13 NFRIA Volunteer Water Quality Monitoring Data Report, 2009 below the reporting limit. The presence of elevated dissolved arsenic concentrations throughout the watershed suggests that arsenic loading may be due to natural sources.

5.3. Cadmium Cadmium is a non-essential element and potential carcinogen. It is widely distributed in the environment at low concentrations and can be toxic to trout around 1.4 ug/L (River Watch). The EPA MCL for cadmium is 5 ug/L. Neither total nor dissolved cadmium concentrations exceeded the River Watch reporting limit of 15 ug/L between October 2004 and October 2007. However, because the laboratory reporting limit is higher than the MCL, it is impossible to conclude that the river consistently meets EPA standards. Colorado has hardness based-standards for cadmium (see Equation 5-1).

5.4. Calcium Calcium is the most abundant cation in the world’s rivers. One of the most important contributors to hardness, calcium commonly results from the leaching of soils or man-made sources such as sewage and industrial wastes. Calcium influences the growth and population dynamics of aquatic life. It is required for plant, animal and bacteria to maintain structural and functional integrity of cell membranes. There are no water quality standards for calcium. High calcium concentrations are a characteristic of highly calcareous soils in the watershed. As seen in Figure 5-3, calcium concentrations at station NF-4a are dramatically higher than other stations at all times of the year, except during spring runoff when it is diluted to nearly the same concentration as stations higher in the watershed. The highest recorded calcium concentration was 179,232 ug/L at station

5-14 NFRIA Volunteer Water Quality Monitoring Data Report, 2009

NF-4a on August 10, 2005. In general, dissolved calcium concentrations increase downstream in the North Fork. A major exception to this trend occurred at station EM-1 where dissolved calcium concentrations were between two to three times greater than the concentrations at NF-1. Note the Y-axis is a logarithmic scale. Scientists have recently begun exploring the calcium threshold of the zebra mussel, an aquatic invasive species that was recently discovered in Colorado. It is believed that calcium levels can limit the zebra mussel’s potential range. A study from the California Sea Grant7 found that zebra mussels are unlikely to become established in waters with calcium concentrations below 20 mg/l (2000 ug/l) unless there is an upstream source of larvae from water with higher calcium levels. Figure 5-3 shows that if Zebra Mussels do invade the Gunnison Basin, the North Fork would provide an optimal habitat in regards to calcium concentrations.

5.5. Copper Copper is a naturally occurring trace element. At low concentrations, copper is an essential micronutrient that is used in cellular metabolism and oxygen transport. At high concentrations, copper can be toxic to aquatic life. The state of Colorado has developed hardness-based aquatic life standards for copper (See Equation 5-2). Figure 5-4 shows dissolved copper concentrations for selected stations. Overall, dissolved copper concentrations do not exhibit much variation or seasonal trends. In general, concentrations are higher at the upper stations. All but one dissolved copper value was below 4 ug/l and 73% of the reported dissolved copper values were below

5.6. Iron Iron is the fourth most abundant element, by weight, in the earth’s crust. It is naturally present in aquatic systems, but in variable amounts depending on the local geology. Iron is normally present in waterways in its soluble ferrous form (Fe2+). However, iron is easily oxidized into its insoluble form, ferric iron (Fe2+). Iron is an important micronutrient that is required for life in small quantities, but can be toxic in excessive amounts. The Colorado chronic standard for total recoverable iron in the North Fork is 1,000 ug/l. Sections of segment COGUNF06 are on the State Monitoring and Evaluation list for Iron. Figure 5-5 shows dissolved iron concentrations in the North Fork at select stations. Note the Y-axis is a logarithmic scale. Dissolved iron in the North Fork exceeded this standard at site NF-2 in May, 2005 and at site NF-3 in June, 2005. In alkaline streams, such as the North Fork, iron primarily exists in colloidal and particulate forms. This is because iron solubility is very low above pH 5 (Wetzel 2001). Iron in the North Fork exists primary in a solid state. Insoluble8 iron comprised over 90% of the total iron detected in the North Fork in 80% of the samples. Solid iron complexes in the North Fork are likely a function of soil erosion.

Figure 5- 6 shows that total iron concentrations increase during spring runoff and storm events. The highest recorded total iron concentration was 29,010 ug/L at EM-1 in October 2006. In general, station EM-1 exhibited the highest total iron values. This is probably associated with the high sediment loads associated with East Muddy Creek.

5.7. Lead Lead is a non-essential element that is toxic to aquatic life in the 10-100 ug/l range (River Watch 2006). Natural occurrences of lead in aquatic systems are rare, but commonly occur in ores with zinc, silver and copper. Lead concentrations in the North Fork are very low. Only 11% of the reported total lead concentrations exceeded the River Watch laboratory reporting limit of 3 ug/L during the reporting period. Colorado has hardness-based standards for dissolved lead (see Equation 5-3). Lead concentrations were well below the acute standard. The North Fork exceeded the chronic standard twice in 2007: NF-3 in October and NF-4a in May. Table 5-2 lists the four instances when dissolved led was detected (i.e. exceeded the River Watch laboratory reporting limit) during the sample period. Note that all four exceedances occurred in 2007.

5.8. Manganese Manganese is a naturally occurring free (uncombined) element that usually occurs with iron. It is an essential element in plant and animal metabolism, but toxic in excessive amounts. Colorado has hardness based-standards for manganese (see Equation 5-4). Dissolved manganese concentrations were well below acute and chronic state standards at all stations.

5.9. Magnesium Like calcium, magnesium is a major component of hardness and is primarily derived from the weathering of rocks. Magnesium is much more soluble than calcium and rarely precipitates. There are no water quality standards for magnesium. Figure 5- 7 shows magnesium concentrations from representative stations on the North Fork. Note that the Y-axis is a logarithmic scale. The highest reported total magnesium value in the North Fork, 78,238 ug/L, was on August 14, 2005 at NF-5. In general, total magnesium concentrations increase longitudinally. However, EM-1 generally exhibited higher total magnesium values than NF-1. Figure 5-7 also shows that magnesium values appear to be diluted by spring runoff and concentrate during late summer low flow conditions. This suggests that groundwater contributes magnesium to the North Fork.

5.10. Selenium Selenium is a naturally occurring trace element that is needed for metabolism in aquatic and humans. Selenium is toxic in high amounts and is known to cause reproductive failure and deformities in fish and aquatic birds (Selenium Taskforce). Selenium is widely distributed in rocks, soils and living organisms. In the North Fork watershed, selenium is commonly associated with the widespread Mancos shale. Irrigated agriculture can increase the amount of selenium in surface and ground water. Deep percolation from irrigation can mobilize large quantities of selenium in groundwater where it eventually concentrates in streams, ponds, reservoirs, lakes and wetlands. The Gunnison/Grand Valley Selenium Task Force has been studying selenium for over a decade. The Taskforce found that upstream of major irrigated areas in the Gunnison basin, selenium concentrations are generally less than 1 ug/L, but downstream from irrigated areas selenium concentrations of surface waters often exceeded 5 ug/L. The State of Colorado has numeric standards for dissolved selenium. Figure 5-8 shows dissolved selenium concentrations that exceeded State standards from all stations monitored by Network Volunteers since 2001. The acute standard (18.4 ug/L) was not exceeded during the reporting period. The chronic standard (4.6 ug/L) was exceeded at all stations at least one time, as outlined in Table 5-3. Note that the River Watch laboratory reporting limit (5 ug/L) is higher than the chronic standard. Therefore, we can not conclusively say that all the samples below the River Watch laboratory reporting limit did not exceed the chronic standard.

Table 5-3 shows that, overall, the greatest detected selenium impairments occurred at stations on river segments included in the 303(d) list for selenium. Station NF-5 had the highest number of exceedances (24) and the highest reported selenium concentration (13.2 ug/L). However, Table 5-3 also indicates that selenium pollution exists in segments not on the 303(d) lists. Stations EM-1 and TC-1 show repeated exceedances of the chronic standard for selenium. There is relatively little irrigated agriculture above Paonia Reservoir; therefore station EM-1 may represent ambient selenium concentrations in the watershed.

Figure 5-9 shows the distribution of peak annual dissolved selenium loads in the North Fork. Load calculations are a function of concentration and discharge, and are particularly helpful in determining pollution sources. The highest dissolved selenium loads occurred in the lower watershed at stations NF-3a and NF-4a. Station NF-3a is located below the Town of Paonia and station NF-4a is below the Town of Hotchkiss, at the confluence of the North Fork and Leroux Creek (see Figure 4-9). The majority of the irrigated agriculture in the North Fork watershed occurs between the Towns of Paonia and Hotchkiss and within the Leroux Creek Drainage. The high selenium loads at stations NF-3a and NF-4a support the hypothesis that irrigated agriculture is a major contributor of selenium in the North Fork.

5.11. Zinc Zinc is a naturally occurring element that is essential for cell growth. It can bioaccumulate and is toxic to aquatic life at concentrations above 50 ug/L (River Watch 2006). Colorado has hardness-based zinc standards (Equation 5-5). Dissolved zinc concentrations in the North Fork were well below both the acute and chronic standards.

6. BACTERIA DATA Total coliform bacteria is a collection of relatively harmless microorganisms that live in the intestines of warm and cold blooded animals and aide in digestion. Fecal coliforms are a subset of intestinal bacteria that are associated only with the fecal material of warm-blooded animals. The most common type of fecal coliform is Escherichia coli (E. coli). The presence of E. coli in aquatic environments indicates that water has been contaminated with fecal materials from sewage or animal waste. This is an important water quality indicator because the presence of fecal contamination means water may be contaminated by waterborne pathogenic diseases such as typhoid fever and hepatitis. E. coli can be washed into water ways during rainfall, snow melt and other precipitation events. Sources of E. coli in the North Fork watershed include livestock, septic systems, waste water treatment effluent, and wildlife. The State of Colorado evaluates compliance with surface water bacteria standards using a geometric mean (the nth root of the product of n numbers). E. coli standards in the North Fork vary seasonally and by WBID segment (see Table 1-3 for standards by WBID segment). The following section summarizes the results from bacteria data collected from 2005 through 2008. The complete dataset can be found in the appendix. Table 6-1 North Fork E. coli Exceedances

Table 6-1 outlines the instances where the monthly geometric mean exceeded water quality standards9. EM-1 had the greatest number of exceedances (6), followed by NF-4a (5) and NF-5 (2). There were five (5) exceedances in 2005, eight (8)

9 Note that E. coli is reported in MPN (most probable number), but the standard is reported by CFU (colony forming units). CFU is a direct count of living organisms while MPN values are estimates.

6-1 NFRIA Volunteer Water Quality Monitoring Data Report, 2009 exceedances in 2006, no exceedances in 2007 and two exceedances in 2008. All exceedances occurred during the summer months of July, August and September. The survival of waterborne pathogens, such as E. coli, in streams and rivers is variable. Conditions such as turbidity, oxygen, presence of nutrients and pesticides, pH, organic matter, and solar radiation can impact pathogen survival rates10. In particular, bacteria are known to have significantly longer survival times in sediment- laden waters11. Microorganisms can adsorb to sediment and organic matter, which suggests that the high TSS concentrations seen in the North Fork (see Figure 4-2) may provide harbor for E. coli. Overall, station EM-1 had the highest TSS and E. coli values. In general, E. coli values peaked during summer months. Figures 6-1 through 6-4 show the monthly geometric E. coli means from 2005 through 2008. However, in 2007 (Figure 6-3), the highest reported E. coli values were in March. The winter standard (November through March) for E. coli in segment COGUNF03 is 630 CFU/100mL, so stations NF-3a and NF-5 were not in violation of the State standard. The E. coli concentration at station NF-3a in March 2007 (402 MPN/100mL) was the highest reported value in the four year reporting period. The elevated spring E. coli values may be attributed the snow melt laden with waste from cattle concentrating in river corridors. This hypothesis, however, is not supported by elevated nitrogen concentrations during the same sample event. E. coli (2005) 450

7. MACROINVERTEBRATE DATA Biological monitoring focuses on the aquatic organisms that live in streams and rivers. Changes that occur in the number and types of organisms present in a stream system may indicate the effects of human activity in a stream. Biological monitoring is based on the fact that different species react to pollution in different ways. Pollution-sensitive organisms are more susceptible to the effects of physical or chemical changes in a stream than other organisms. These organisms act as indicators of the absence of pollution. Pollution-tolerant organisms are less susceptible to changes in the environment and act as an indirect measure of pollution. Pollution-sensitive organisms will decrease in number or disappear in polluted streams, while pollution-tolerant organisms will increase in number and variety. Benthic macroinvertebrates are animals without backbones that are large enough to see with the naked eye and live on the river bottom. Macroinvertebrates are commonly used as water quality indicators because they are easy to sample, continuous indicators and sit near the bottom of the aquatic food web. Macroinvertebrates were sampled four times between October 2004 and October 2007. Network volunteers collected macroinvertebrates using the River Watch rocky substrate collection method. Samples were collected from the kick net and sent to a River Watch laboratory in Ft. Collins for professional analysis. A complete listing of all macroinvertebrate data can be found in the appendix. Table 7-1 summarizes seven common metrics uses to evaluate macroinvertebrate communities. The table briefly defines each metric and indicates how the predicted community response to disturbance. Note that samples were collected at different stations in different years. Overall, the metrics indicate that the North Fork has a healthy and thriving macroinvertebrate community. There are no major differences in community structure and abundance between stations, as indicated by the total number of organisms and taxa richness. This suggests that biological community has not experienced any significant disturbance. The metrics that evaluate pollution tolerance, % EPT and HBI, indicate that the macroinvertebrate community is relatively intolerant of pollution. Nearly half of the macroinvertebrates collected are pollution-sensitive EPT taxa and the HBI values indicate good to excellent water quality. The trophic structure in streams is often defined in comparison to the River Continuum Concept (RCC). The RCC describes the longitudinal changes that occur in a river as related to differences in size and terrestrial setting. The RCC is particularly useful for describing how ecological function varies along riverine ecosystems. Figure 7-1 illustrates the distribution of functional feeding groups at stations in the North Fork. The North Fork, primarily a 4rd order stream, functions like a RCC mid- order stream. This is expected because the North Fork does not have a wooded riparian zone to contribute shade and allochthonous material to the system. The distribution of functional feeding groups (e.g. high percentage of collectors and scrapers) suggests that the North Fork has a variety of energy inputs and is partially autotrophic.

8. CONCLUSIONS The water quality data presented in this report was not collected for compliance or regulatory purposes; rather these data are designed to give background information on water quality conditions in the watershed, help water users understand seasonal and natural variation within the watershed, and provide a basic understanding of how the North Fork River compares to State stream standards. Water quality samples collected by the Network indicated that overall, the North Fork River has moderate to good water quality considering the geologic setting and varied land uses. Field Parameters The geology and natural soils of the watershed provide the North Fork with the capacity to buffer against changes in pH and the toxic effects of metals. Buffering capacity, as measured by Total Hardness and Total Alkalinity, was highest at downstream locations. Irrigation dependent base-flows are the most likely source of the salts that contribute to hardness and alkalinity. The North Fork is a slightly basic system and pH values are within the allowed range for Aquatic Life. The alkaline character of the water decreases the solubility of many of the toxic metals that are present in the North Fork. The segments of the North Fork monitored by Network volunteers are classified as Aquatic Life Cold 1. This means that portions of the North Fork are subject to chronic temperature standards. These temperature standards were enacted to protect the cold-water fisheries that are native to the North Fork. The temperature standard, 20 degrees C, was exceeded four times during the sample period. Cool temperatures are critical to cold-blooded animals that are unable to control their body temperatures. Furthermore, cold water can hold more oxygen than warm water. Cold water fish need oxygen rich environments to thrive. In the North Fork, dissolved oxygen (DO) levels dropped below the State Standard, 6.0 mg/L, twice. However, dissolved oxygen and temperature do not present a significant threat to the fishery of the North Fork, but they should continue to be monitored. Nutrients Network Volunteers have monitored nutrients since 2001. In general, nutrient concentrations were well below state and/or federal standards indicating there are no significant nutrient problems in the North Fork Watershed. Sulfate concentrations near Hotchkiss routinely exceeded secondary drinking water standards. This is not a concern, as downstream reaches of the North Fork are not used as a drinking water supply. Sediment loads in the North Fork are variable, depending on flow conditions. Total Suspended Solids (TSS) concentrations exhibited a direct relationship with flow conditions. High flow events generally resulted in elevated TSS concentrations. In general, TSS concentrations were highest at station EM-1. EM-1, located on East Muddy Creek, is above Paonia Reservoir. The reservoir may serve as a settling basin for the sediment load of East Muddy Creek. This may explain why downstream TSS concentrations at NF-1 were lower than at EM-1. There are no State standards for phosphorus, but total phosphorus concentrations in the North Fork are well below levels associated with eutrophication. Phosphorus is a naturally occurring nutrient that binds tightly to soil particles. Total phosphorus (TP)

8-1 NFRIA Volunteer Water Quality Monitoring Data Report, 2009 concentrations, like TSS concentrations, are highly dependent on flow conditions. TP concentrations generally spiked during spring runoff. Nitrate concentrations were below the Maximum Contaminant Level (MCL) of 10 mg/L. Nitrate levels increased during the winter baseflow conditions, indicating that nitrate is present in groundwater. Common nitrate sources include fertilizer, animal waste, and wastewater effluent. Peak winter nitrate loads in the North Fork were highest below the Town of Hotchkiss at station NF-4a. Water quality at NF-4a is influenced by the Leroux Creek drainage, the Town of Hotchkiss waste water treatment plan, and cattle ranches that straddle the river. Ammonia exceeded the State chronic standard one time, at station NF-5 on December 18, 2004. Metals With the exception of arsenic and selenium; water quality data indicates that dissolved metals are not a significant concern in the North Fork. Aluminum, copper, iron and lead only occasionally exceeded State chronic standards. Portions of the North Fork have been listed on the State Monitoring and Evaluation list for iron. However, iron does not appear to present a significant threat to the North Fork. Dissolved cadmium, magnesium and zinc concentrations were often below River Watch laboratory reporting limits. In 2007, dissolved arsenic was detected at concentrations above the State chronic standard at nearly every active station. The widespread detection of arsenic, both above and below active hard rock mining locations, suggests natural landscape sources. Selenium is a known impairment in the Gunnison Basin. Segments of the North Fork are on the Colorado 303(d) List of Impaired Streams needing TMDLs. In the North Fork, the chronic standard was exceeded at least one time at every station. Water quality at stations in the lower half of the watershed, NF-3 and below, regularly exceeded State standards. The highest dissolved selenium loads occurred in the lower watershed at stations NF-3a and NF-4a. Station NF-3a is located below the Town of Paonia and station NF-4a is below the Town of Hotchkiss, at the confluence of the North Fork and Leroux Creek (see Figure 4-9). The majority of the irrigated agriculture in the North Fork watershed occurs between the Towns of Paonia and Hotchkiss and within the Leroux Creek Drainage. The high selenium loads at stations NF-3a and NF-4a support the hypothesis that irrigated agriculture is a major contributor of selenium in the North Fork. Bacteria The presence of E. coli in aquatic environments indicates that water has been contaminated with fecal materials from sewage or animal waste. In general, E. coli values peaked during summer months. However, in 2007, the highest reported E. coli values were in March. The elevated spring E. coli values may be attributed the snow melt laden with waste from cattle concentrating in river corridors. This hypothesis, however, is not supported by elevated nitrogen concentrations during the same sample event. Macroinvertebrates Overall, the North Fork has a healthy and thriving macroinvertebrate community. The metrics that evaluate pollution tolerance, % EPT and HBI, indicate that the macroinvertebrate community is relatively intolerant of pollution. Nearly half of the macroinvertebrates collected are pollution-sensitive EPT taxa and the HBI values indicate good to excellent water quality.
