Bureau of Reclamation & RGRWA Page 10 Studies are Underway to Better Characterize the Water Resources of the Lower Pecos River and Devils River Watersheds Page 11 Related Studies Suggest There Is Limited Groundwater Flow from Adjacent Watersheds Distinct Watersheds Related studies of the Edwards Aquifer suggest watersheds on the edge of the Edwards Plateau act separately and there is limited groundwater flow between adjacent watersheds Page 12 This suggests There Is Limited Groundwater Flow Between the Pecos, Devils, and Sycamore Watersheds Water in each watershed will tend to stay in its watershed. It is unlikely that surface water or significant groundwater will flow from one watershed to an adjacent watershed, particularly where aquifers are shallow.

Page 18 Water Is Conveyed as Groundwater Upstream and Surface Water Downstream Flow is as groundwater upstream where river beds are dry …and as surface water downstream Page 19 It is important to note that all high capacity wells in the Devils River watershed are located along major river channels This observation is supported by a review of over 2,200 wells in the TWDB database There are 752 wells with measured capacity in the TWDB database. When plotted on a map of the Devils River watershed, it is apparent that high capacity water wells are only located near river channels Page 20 A Graph of These Data Support This Observation Distance From River Channel Versus Well Capacity 3,000 ) 2,500 Virtually all wells with capacity of 500 gpm gpm are within 1.5 miles of a river 2,000 1,500 1,000 Well Pump Rate ( Well 500 0 0 2 4 6 8 10 12 14 16 Distance from Closest River Channel (mi) Page 21 The well data suggest there are preferential flow paths in the subsurface located near rivers that carry significant water. If we consider the Edwards- Trinity Aquifer a sponge, then these preferential flow paths can be thought of as pipes in the sponge Page 22 Step 1: The Edwards Plateau Was Formed by Sea Sediments that Solidified Then Lifted Over 10s of Millions of Years Page 23 Step 2: River Basins Are Formed as the Edwards Plateau Is Uplifted and Rock Is Eroded Once started, these river channels and basins probably retain the same alignment over millions of years Page 24 Step 3: Rain Water Is Focused into River Beds and Acts as a Mild Acid That Dissolves the Limestone Incised River Channels Preferential Flow Paths The preferential flow paths that are formed may be a “pipe”, but it is more likely the flow paths are simply zones of enhanced permeability Page 25 Two Important Points: 1)These preferential flow paths are in bed rock, not gravel beds 2) You cannot assume to have high capacity wells everywhere in Edwards-Trinity Aquifer just because you happen to have a high-capacity well that’s near a river channel Page 26 Supporting Proof of Preferential Flow Channels in River Channels Dye tracer tests in Sonora confirm the presence of preferential flow in Devils River channel Groundwater will flow at most a few 10s of feet/yr in a porous media aquifer such as the Carrizo-Wilcox Preliminary results from the Sonora tracer test suggests groundwater travels a half to one mile a day in the “pipes” associated with Devils River Page 27 What is needed to build a model of the Devils River 1) Need to watershed? model the entire watershed 2) Need to add pipes Page 28 How is Groundwater Flow Characterized by the Texas Groundwater Development Board?

    THE NATIVE FISH FAUNA OF MAJOR DRAINAGES EAST OF THE CONTINENTAL DIVIDE IN NEW MEXICO A Thesis Presented to the Graduate Faculty of Biology Eastern New Mexico University In Partial Fulfillment of the Requirements fdr -the7Degree: Master of Science in Biology by Michael D. Hatch December 1984 TABLE OF CONTENTS Page Introduction Study Area Procedures Results and Discussion Summary Acknowledgements Literature Cited Appendices Abstract INTRODUCTION r (t. The earliest impression of New Mexico's native fish fauna =Ems during the 1850's from naturalists attached to various government survey parties. Without the collections from these and other early surveys, the record of the native fish fauna would be severely deficient because, since that time, some 1 4 native species - or subspecies of fish have become extirpated and the ranges of an additionial 22 native species or subspecies have become severly re- stricted. Since the late Miocene, physiographical changes of drainages have linked New Mexico, to varying degrees, with contemporary ichthyofaunal elements or their progenitors from the Rocky Mountains, the Great Plains, the Chihuahuan Desert, the Mexican Plateau, the Sonoran Desert and the Great Basin. Immigra- tion from these areas contributed to the diversity of the state's native ichthyofauna. Over the millinea, the fate of these fishes waxed and waned in ell 4, response to the changing physical and _chenaca-l-conditions of the surrounding environment. Ultimately, one of the most diverse fish faunas of any of the interior southwestern states developed. Fourteen families comprising 67 species of fish are believed to have occupied New Mexico's waters historically, with strikingly different faunas evolving east and west of the Continental Divide.

  • Stormwater Management Program 2013-2018 Appendix A
    Appendix A 2012 Texas Integrated Report - Texas 303(d) List (Category 5) 2012 Texas Integrated Report - Texas 303(d) List (Category 5) As required under Sections 303(d) and 304(a) of the federal Clean Water Act, this list identifies the water bodies in or bordering Texas for which effluent limitations are not stringent enough to implement water quality standards, and for which the associated pollutants are suitable for measurement by maximum daily load. In addition, the TCEQ also develops a schedule identifying Total Maximum Daily Loads (TMDLs) that will be initiated in the next two years for priority impaired waters. Issuance of permits to discharge into 303(d)-listed water bodies is described in the TCEQ regulatory guidance document Procedures to Implement the Texas Surface Water Quality Standards (January 2003, RG-194). Impairments are limited to the geographic area described by the Assessment Unit and identified with a six or seven-digit AU_ID. A TMDL for each impaired parameter will be developed to allocate pollutant loads from contributing sources that affect the parameter of concern in each Assessment Unit. The TMDL will be identified and counted using a six or seven-digit AU_ID. Water Quality permits that are issued before a TMDL is approved will not increase pollutant loading that would contribute to the impairment identified for the Assessment Unit. Explanation of Column Headings SegID and Name: The unique identifier (SegID), segment name, and location of the water body. The SegID may be one of two types of numbers. The first type is a classified segment number (4 digits, e.g., 0218), as defined in Appendix A of the Texas Surface Water Quality Standards (TSWQS).

  • Water-Resource Management of the Devils River Watershed Final Report
    Water-Resource Management of the Devils River Watershed Final Report August 11, 2017 Nathaniel Toll, S. Beth Fratesi, Ronald T. Green, F. Paul Bertetti, and Rebecca Nunu Earth Science Section Space Science Division Southwest Research Institute® ABSTRACT The Devils River watershed in south-central Texas has been recognized as one of the remaining pristine rivers in the state. Adding to its importance, the Devils River is a key tributary to the Rio Grande, providing essential freshwater flows to south Texas and the Rio Grande Valley. The Devils River watershed basin is being threatened by proposed large-scale groundwater export projects. This study was undertaken to evaluate what impact groundwater pumping in the upper Devils River watershed would have on downstream discharge in the Devils River. The watershed is located in a semi-arid environment with modest distributed recharge, oftentimes less than 1-2 cm/year [0.4-0.8 in/year]. The Edwards-Trinity (Plateau) Aquifer of the Devils River watershed is characterized as a karstic carbonate aquifer with preferential flow paths that align with major river channels. Water chemistry, water budget, hydraulics, and geophysical imaging data were used to corroborate this conceptualization. A coupled surface-water/groundwater model was assembled to replicate the hydraulics of the Edwards-Trinity Aquifer to provide a defensible tool to assess the impact of pumping on river flow. The surface-water model was assembled to determine recharge to the groundwater model. The conduit/diffuse groundwater model replicates both fast conduit flow and slow diffuse flow in the Edwards-Trinity Aquifer. The model provides, for the first time, a numerical groundwater flow model that replicates the hydraulic dominance of preferential flow paths in the karstic Edwards-Trinity Aquifer of the Devils River watershed.

The bridge de igner of today is both artist and engineer. He understands the potential for strength and beauty which is inherent in steel structures, and he knows that aesthetic appearance can be achieved at no sacrifice of efficiency or economy. The simple grace of a highway overpass, no less than the majestic sweep of a river crossing reflects a creative integration of structure, func­ tion and form, skillfully executed in beautiful bridges of steel. To promote a more widespread appreciation of the aesthetics of steel bridges and to honor the architectural excellence of modern bridge design, the American Institute of Steel Construction sponsors an annual Prize Brid'ge Competition. Each year a distinguished Jury of Award, composed of leading art directors, architects and engineers, selects the steel bridges which it judges to be the most beautiful of those opened to traffic in the • United States during the previous year.
