Acknowledgments The Investigating Agencies would like to take this opportunity to thank the many individuals who have contributed to the success of this project. The development of this watershed protection plan would not have been possible without the cooperation and consolidation of efforts from everyone involved. First, we would like to thank the many landowners and other interested parties who have attended project meetings, participated in surveys, and provided invaluable input that has guided the development of this document. Your interest in this project and the Pecos River was and will continue to be instrumental in ensuring the future restoration and improvement of the health of this important natural resource. While there are too many of you to name here, we hope that your interest, involvement, and willingness to implement needed management measures will grow as progress is made and new phases of the watershed protection plan are initiated. Our gratitude is extended to the following individuals who have contributed their support, technical expertise, time, and/or advice during the project: Greg Huber, J.W.

  • Gazetteer of Streams of Texas
    DEPARTMENT OF THE INTERIOR FRANKLIN K. LANE, Secretary UNITED STATES GEOLOGICAL SURVEY GEORGE OTIS SMITH, Director Water-Supply Paper 448 GAZETTEER OF STREAMS OF TEXAS PREPARED UNDER THE DIRECTION OF GLENN A. GRAY WASHINGTON GOVERNMENT FEINTING OFFICE 1919 GAZETTEER OF STREAMS OF TEXAS. Prepared under the direction of GLENN A. GRAY. INTRODUCTION. The following pages contain a gazetteer of streams, lakes, and ponds as shown by the topographic maps of Texas which were pre­ pared by the United States Geological Survey and, in areas not covered by the topographic maps, by State of Texas county maps and the post-route map of Texas. For many streams a contour map of Texas, prepared in 1899 by Robert T. Hill, was consulted, as well as maps compiled by private surveys, engineering corporations, the State Board of Water Engineers, and the International Boundary Commission. An effort has been made to eliminate errors where practicable by personal reconnaissance. All the descriptions are based on the best available maps, and their accuracy therefore depends on that of the maps. Descriptions of streams in the central part of the State, adjacent to the Bio Grande above Brewster County, and in parts of Brewster, Terrell, Bowie, Casg, Btirleson, Brazos, Grimes, Washington, Harris, Bexar, Wichita, Wilbarger, Montague, Coke, and Graysoh counties were compiled by means of topographic maps and are of a good degree of accuracy. It should be understood, however, that all statements of elevation, length, and fall are roughly approximate. The Geological Survey topographic maps used are cited in the de­ scriptions of the streams and are listed below.

  • Report 360 Aquifers of the Edwards Plateau Chapter 2
    Chapter 2 Conceptual Model for the Edwards–Trinity (Plateau) Aquifer System, Texas Roberto Anaya1 Introduction The passage of Senate Bill 1 in 1997 established a renewed public interest in the State’s water resources not experienced since the drought of the 1950s. Senate Bill 1 of 1999 and Senate Bill 2 of 2001 provided state funding to initiate the development of groundwater availability models for all of the major and minor aquifers of Texas. The development and management of Groundwater Availability Models (GAMs) has been tasked to the Texas Water Development Board (TWDB) to provide reliable and timely information on the State’s groundwater resources. TWDB staff is currently developing a GAM for the Edwards–Trinity (Plateau) aquifer. An essential task in the design of a numerical groundwater flow model is the development of a conceptual model. The conceptual model is a generalized description of the aquifer system that defines boundaries, hydrogeologic parameters, and hydrologic stress variables. The conceptual model helps to compile and organize field data and to simplify the real-world aquifer flow system into a graphical or diagrammatical representation while retaining the complexity needed to adequately reproduce the system behavior (Anderson and Woessner, 1992). The first step in the development of a conceptual model is to delineate the study area and form an understanding of its physical landscape with regard to the physiography, climate, and geology. Another early step also involves the research and investigation of previous aquifer studies. Intermediate steps bring together all of the information for establishing the hydrogeologic setting which consists of the hydrostratigraphy, structural geometry, hydraulic properties, water levels and regional groundwater flow, recharge, interactions between surface water and groundwater, well discharge, and water quality.

ABSTRACT Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. Ecoregion frameworks are valuable tools for environmental research, assessment, management, and monitoring of ecosystems and ecosystem components. They have been used for setting resource management goals, developing biological criteria and establishing water quality standards. In a cooperative project with the Texas Commission on Environmental Quality, the U.S. Environmental Protection Agency, the U.S. Department of Agriculture, and other interested state and federal agencies, we have defined ecological regions of Texas at two hierarchical levels that are consistent and compatible with the U.S.
