Lavon Lake Watershed Protection Plan Lavon Lake Watershed Protection Plan Developed by The Lavon Lake Watershed Partnership June 2017 Cover photo of Lavon Lake. Lavon Lake Watershed Protection Plan Prepared for the Lavon Lake Watershed Partnership by North Texas Municipal Water District Texas A&M AgriLife Extension Service Texas State Soil and Water Conservation Board Funding for the development of this Watershed Protection Plan was provided by the Texas State Soil and Water Conservation Board’s State Nonpoint Source Grant Program and the North Texas Municipal Water District. Page i Acknowledgements This document and the efforts behind its completion are the result of collaboration and cooperation between many different groups and individuals. These stakeholders have played an important role in the Lavon Lake Watershed Partnership. First and foremost, the Partnership wishes to express thanks to the members of the Steering Committee for their investments of time and energy in participating throughout the process. Without their direction and support, development of this plan would not have been possible. Through the Lavon Lake Watershed Protection Plan, their efforts serve as an example to all stakeholders of the importance of active stewardship of water resources. The Lavon Lake Watershed Partnership also would like to thank the members of the Technical Advisory Group for their assistance and advice: North Texas Municipal Water Texas Department of Agriculture District Texas State Soil and Water Texas Commission on Conservation Board Environmental Quality U.S. Army Corps of Engineers Texas Farm Bureau Texas Parks & Wildlife Department USDA Natural Resources Conservation Service U.S. Environmental Protection Agency USDA Farm Service Agency Texas A&M AgriLife Research and U.S. Geological Survey Extension Services The Partnership would like to thank Galen Roberts with the North Texas Municipal Water District, Dr. Jake Mowrer with Texas A&M AgriLife Extension, and Liza Parker and Mitch Conine with the Texas State Soil and Water Conservation Board for authoring the Lavon Lake Watershed Protection Plan. The Partnership also expresses thanks to Dr. R. Karthikeyan, Kyna Borel, and Vaishali Swaminathan of the Texas A&M University Biological and Agricultural Engineering Department and David Shoemate and Dr. Raghavan Srinivasan of the Texas A&M University Spatial Sciences Laboratory for their expertise and tremendous assistance in analyzing land use and water quality for this project. The Partnership is especially grateful to the Texas State Soil and Water Conservation Board for technical and financial support of this effort. Funding provided through the TSSWCB enabled the development of this Watershed Protection Plan and established a solid foundation for watershed stewardship in Lavon Lake. Page ii Statement of Purpose Lavon Lake is a vital resource for the area, providing municipal water supply, flood control, wildlife habitat, and opportunities for recreation. Over 1.6 million North Texas residents rely on Lavon Lake as their primary source of drinking water. The land surrounding the lake supports a wide array of agricultural, industrial, and urban uses. Although the majority of the watershed is rural, the southwestern portion of the watershed is one of the most rapidly developing urban areas in the nation. Agriculture remains a vital part of the local economy, but the economic landscape in the watershed is changing as land uses shift from rural to urban. In 2010, two tributaries to Lavon Lake were identified as impaired due to elevated levels of E. coli bacteria. The Lavon Lake Watershed Protection Plan was developed using a stakeholder process to provide a foundation for addressing these bacteria issues and to protect water quality in Lavon Lake and its tributaries from other pollutants of concern. By identifying key water quality issues and determining their contributing factors, management programs and public outreach efforts can be targeted to protect the vital water resources of this watershed. The Lavon Lake Watershed Protection Plan incorporates analysis of existing water quality data and investigation of potential pollutant sources to develop a strategy for addressing water quality concerns. Stakeholders are any individual or group that may be directly or indirectly affected by activities implemented to protect water quality, such as citizens, civic organizations, businesses, municipalities, county governments, river authorities, soil and water conservation districts, agricultural committees, nonprofit organizations, and state and federal agencies. This Watershed Protection Plan is a means by which stakeholders can become more familiar with the Lavon Lake watershed and help protect the quality and health of their water resources through adoption of voluntary management practices. It helps focus protection efforts and enables financial and technical assistance to facilitate improvements in the Lavon Lake watershed. The plan is intended to be a living document, adjusted to include new data and modified as conditions in the watershed change over time. It will evolve as needs and circumstances dictate and will be guided by stakeholders as they undertake active stewardship of the watershed.

  • Chapter 307: Texas Surface Water Quality Standards (4/9/2008)
    Revisions to §307 - Texas Surface Water Quality Standards (updated November 12, 2009) EPA has not approved the revised definition of “surface water in the state” in the TX WQS, which includes an area out 10.36 miles into the Gulf of Mexico. Under the CWA, Texas does not have jurisdiction to regulate water standards more than three miles from the coast. Therefore, EPA’s approval of the items in the enclosure recognizes the state’s authority under the CWA out to three miles in the Gulf of Mexico, but does not extend past that point. Beyond three miles, EPA retains authority for CWA purposes EPA’s approval also does not include the application the TX WQS for the portions of the Red River and Lake Texoma that are located within the state of Oklahoma. Finally, EPA is not approving the TX WQS for those waters or portions of waters located in Indian Country, as defined in 18 U.S.C. 1151. The following sections have been approved by EPA and are therefore effective for CWA purposes: • §307.1. General Policy Statement • §307.2. Description of Standards • §307.3. Definitions and Abbreviations (see item under “no action” section below) • §307.4. General Criteria • §307.5. Antidegradation • §307.6. Toxic Materials.

  • The Proposed Fastrill Reservoir in East Texas: a Study Using
    THE PROPOSED FASTRILL RESERVOIR IN EAST TEXAS: A STUDY USING GEOGRAPHIC INFORMATION SYSTEMS Michael Ray Wilson, B.S. Thesis Prepared for the Degree of MASTER OF SCIENCE UNIVERSITY OF NORTH TEXAS December 2009 APPROVED: Paul Hudak, Major Professor and Chair of the Department of Geography Samuel F. Atkinson, Minor Professor Pinliang Dong, Committee Member Michael Monticino, Dean of the Robert B. Toulouse School of Graduate Studies Wilson, Michael Ray. The Proposed Fastrill Reservoir in East Texas: A Study Using Geographic Information Systems. Master of Science (Applied Geography), December 2009, 116 pp., 26 tables, 14 illustrations, references, 34 titles. Geographic information systems and remote sensing software were used to analyze data to determine the area and volume of the proposed Fastrill Reservoir, and to examine seven alternatives. The controversial reservoir site is in the same location as a nascent wildlife refuge. Six general land cover types impacted by the reservoir were also quantified using Landsat imagery. The study found that water consumption in Dallas is high, but if consumption rates are reduced to that of similar Texas cities, the reservoir is likely unnecessary. The reservoir and its alternatives were modeled in a GIS by selecting sites and intersecting horizontal water surfaces with terrain data to create a series of reservoir footprints and volumetric measurements. These were then compared with a classified satellite imagery to quantify land cover types. The reservoir impacted the most ecologically sensitive land cover type the most. Only one alternative site appeared slightly less environmentally damaging. Copyright 2009 by Michael Ray Wilson ii ACKNOWLEDGMENTS I would like to acknowledge my thesis committee members, Dr.

  • 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).

  • Texas Water Resources Institute
    Texas Water Resources Institute Summer 1989 Volume 15 No. 2 Optimizing Reservoir Management New Strategies Including Systems Operation and Reallocation May Boost Reservoir Yields By Ric Jensen Information Specialist, TWRI Many experts believe Texas can increase its surface water supplies without building new dams and reservoirs. The answer isn't magic. The solution is better management and coordination of existing reservoirs. New strategies/hat make every drop of water count include operating a group of reservoirs as a coordinated system; converting some reservoir storage space from hydropower production, flood control, and navigation to water supplies; and timing water levels in reservoirs to correspond to seasonal differences in streamflows and water demands. Scientists are learning more about the quality of water in lakes and how man's activities affect the chemical makeup of reservoirs. A number of important developments are already taking place. Both the City of Dallas and the Brazos River Authority manage their reservoir systems so that releases of water are tied to climate conditions water demands. The Lower Colorado River Authority (LCRA) has recently submitted a management plan to the Texas Water Commission (TWC) that could allow LCRA to sell "interruptible water supplies" during wet years. Opportunities to reallocate storage space in Texas reservoirs have been summarized in recent report by the U.S. Army Corps of Engineers (COE). Otherstudies have described how systems operation could increase water supplies in reservoirs in the Sabine, Trinity, and Trinity-San Jacinto River basins. 1 Optimizing reservoir management has been the focus of many university research projects. Scientists at Texas A&M University have been studying the Brazos River basin.
