Smith Committee Members, Peter J. Hugill Christian Brannstrom Bradford P. Wilcox Head of Department, Douglas J. Sherman May 2007 Major Subject: Geography iii ABSTRACT Changing Patterns and Perceptions of Water Use in East Central Texas Since the Time of Anglo Settlement. (May 2007) Wendy Winborn Patzewitsch, B.A., Trinity University; M.S., Southern Methodist University Chair of Advisory Committee: Dr. Jonathan M. Smith Patterns and perceptions of water use have changed since Anglo settlement in Texas in the early nineteenth century. Change has not been constant, gradual, or linear, but rather has occurred in fits and spurts. This pattern of punctuated equilibrium in water use regimes is the central finding of this dissertation. Water use is examined in terms of built, organizational, and institutional inertias that resist change in the cultural landscape. Change occurs only when forced by crisis and results in water management at an increasing scale. Perception is critical in forcing response to crisis.

PROPOSED ACTION: TheEl Paso Sector of the United States Border Patrol, the law enforcement arm of the INS, proposes to install fencing, lights, cameras, guardrails and sensors along portions of the American Canal Extension in El Paso, TX. The Proposed Action directly supports the mission of the Border Patrol (BP), and will provide considerable added safety to the field personnel. The project is located near the Rio Grande River in northwestern Texas. All of the project is within the city limits of El Paso. The majority of the Project Location is along a man­ made canal and levee system. Portions of the canal are at times adjacent to industrial areas, downtown El Paso, and mixed commercial with limited residential development.

    Figure: 30 TAC §307.10(1) Appendix A - Site-specific Uses and Criteria for Classified Segments The following tables identify the water uses and supporting numerical criteria for each of the state's classified segments. The tables are ordered by basin with the segment number and segment name given for each classified segment. Marine segments are those that are specifically titled as "tidal" in the segment name, plus all bays, estuaries and the Gulf of Mexico. The following descriptions denote how each numerical criterion is used subject to the provisions in §307.7 of this title (relating to Site-Specific Uses and Criteria), §307.8 of this title (relating to Application of Standards), and §307.9 of this title (relating to Determination of Standards Attainment). Segments that include reaches that are dominated by springflow are footnoted in this appendix and have critical low-flows calculated according to §307.8(a)(2) of this title. These critical low-flows apply at or downstream of the spring(s) providing the flows. Critical low-flows upstream of these springs may be considerably smaller. Critical low-flows used in conjunction with the Texas Commission on Environmental Quality regulatory actions (such as discharge permits) may be adjusted based on the relative location of a discharge to a gauging station. -1 -2 The criteria for Cl (chloride), SO4 (sulfate), and TDS (total dissolved solids) are listed in this appendix as maximum annual averages for the segment. Dissolved oxygen criteria are listed as minimum 24-hour means at any site within the segment. Absolute minima and seasonal criteria are listed in §307.7 of this title unless otherwise specified in this appendix.

  • 1.0 INTRODUCTION 1.1 IBWC Background Information For
    1.0 INTRODUCTION 1.1 IBWC Background Information For centuries the Rio Grande River has been used as a source of irrigation water for agriculture in the El Paso – Juarez area. Even before the Spanish settlement of the area in the later half of the 17th Century, irrigation canals had already been constructed to convey water from the Rio Grande to cultivated fields. By the early 1900s, nearly 9,000 acres of the Rio Grande Valley in the El Paso-Juarez area were being irrigated with water from the river, as detailed in the Historical/Cultural Section of this Assessment, included as Appendix K (“Controlling Water on the Border: The American Canal System, International Boundary and Water Commission, El Paso, Texas” submitted November 1999 by Human Systems Research, Inc., and a Supplemental Report submitted April 2000 by Parsons Engineering Science). Currently in El Paso County, Rio Grande water is used to irrigate approximately 69,000 acres of farmlands and to produce nearly half of El Paso’s potable water. In 1889 the governments of the United States and Mexico established the International Boundary Commission (IBC), which a 1944 Treaty later renamed the International Boundary and Water Commission or IBWC. One of the early actions of the IBC was to discuss delivery of Rio Grande water to Mexico. During the Mexican-American Convention of 1906, the two countries agreed to deliver 60,000 acre-feet of water annually to Mexico at the headgates of the Acequia Madre facility on the southern shore of the Rio Grande in Cd. Juarez, Chihuahua, opposite El Paso, Texas.

  • Current Letting Schedule by District
    T F A R D Data Date: September 27, 2021 Run Date: 9/27/2021 @ 1:04:11 PM FOREWORD * This document contains candidate projects which have been identified by districts as ready for letting or obligation of funds in fiscal year 2022 by TxDOT. There are five sections to this document: 1. Projects that are scheduled to let through the statewide letting process at Austin headquarters 2. Projects that are approved by the TxDOT administration to let by a local entity such as a city or county 3. Other financial obligations that do not go through a letting process 4. Project selected as Comprehensive Development Agreement T 5. Projects selected as Design Build Projects and other financial obligations are funded by variousF funding sources, the details of which are provided on the following page. The State Highway Fund is TxDOT’s traditional method of project funding and in recent years the department has received additional financial tools from the ALegislature to advance projects. The projects and financial obligations in this schedule are based on the current estimated construction costs of the projects and the current forecast of available funds for fiscal year 2022. Changing conditionsR may result in projects being removed or added to this Letting Schedule. These changes could include financial issues such as receiving more or less revenues than forecasted, adjustments to fit within obligation limits, the execution of funding agreements, bids on projects being higher or lower than the project estimates,D and increasing or decreasing cost on existing contracts through change orders or quantity overruns.
