(Texas Water Resources Institute, 2015-11)Bacteria water quality impairments are the most common water quality issue in Texas and are a considerable source of impairments nationally. Fecal indicator bacteria such as Escherichia coli (E. coli) and enterococci derived ...
-
(Texas Water Resources Institute, 2010-12)According to the 2008 Water Quality Inventory and 303(d) List, 291 of the 516 impairments (i.e. 56%) were the result of excessive bacteria. Modeling and bacteria source tracking has identified grazing cattle as a source ...
-
(Texas Water Resources Institute, 2009-01)In September 2006, the Texas Commission on Environmental Quality (TCEQ) and Texas State Soil and Water Conservation Board (TSSWCB) charged a seven-person Bacteria Total Maximum Daily Load (TMDL) Task Force with: * ...
-
(Texas Water Resources Institute, 2008-08)The “Bacterial Monitoring for the Buck Creek Watershed” project was developed in response to the creek’s listing on the Texas Water Quality Inventory and 303(d) List due to a bacterial impairment and subsequent total maximum ...
-
(Texas Water Resources Institute, 2013-04-25)The Bacterial Source Tracking to Support the Development and Implementation of Watershed Protection Plans for the Lampasas and Leon Rivers project was developed to provide supplemental information to stakeholders engaged ...

-
(Texas Water Resources Institute, 2014)In the 2012 Texas Integrated Report and 303(d) List, approximately 48% of the 568 impaired water bodies were caused by high bacteria levels. Once a water body has been listed, the Clean Water Act requires action to be ...
-
(Texas Water Resources Institute, 2015-05)The 2012 Texas Integrated Report – Texas 303(d) List identifies 11 impaired waterbody segments along the Navasota River due to Escherichia coli (E.coli) bacteria (Figure 1). The Clean Water Act (CWA) requires water bodies ...
-
(Texas Water Resources Institute, 2008-04)The Bosque River and its associated watershed face a myriad of water quality challenges. Previous attempts made to address these concerns have met with limited success due to a relatively narrow, specific problem approach. ...
-
(Texas Water Resources Institute, 2008-03)The Bosque River Watershed is located in the Brazos River Basin in central Texas and is facing a suite of water quality issues resulting in sediment, nutrient and bacteria loading. These loadings are potentially derived ...
-
(Texas Water Resources Institute, 1981)The purpose of this study was to quantify the benefits of using a wind energy system for irrigation. The value of wind energy was estimated on both a static basis (where the annual value of wind power was assumed to be ...
-
(Texas Water Resources Institute, 2000-11)The Soil and Water Assessment Tool (SWAT) model was used to simulate the effects ofbrush removal on water yield in 8 watersheds in Texas for 1960 through 1998. Landsat? satellite imagery was used to classify land use, and ...
-
(Texas Water Resources Institute, 2003)The Soil and Water Assessment Tool (SWAT) model was used to simulate the effects of brush removal on water yield in four watersheds in Texas for 1960 through 1999. Methods used in this study were similar to methods used ...
-
(Texas Water Resources Institute, 2014-09)Through the Building Partnerships for Cooperative Conservation in the Trinity River Basin project, funded by U.S. Environmental Protection Agency (EPA) with Clean Water Act (CWA) §319(h) funds through the Texas State ...
-
(Texas Water Resources Institute, 2003-05)This technical report contains summaries of presentations that were given at the Groundwater Conservation District Seminar Series on May 28, 2003, at the Texas A&M University George Bush Presidential Conference ...
-
(TEXAS NATURAL RESOURCE CONSERVATION COMMISSION, 2002)Through support from the Texas On-Site Wastewater Treatment Research Council, a project to search the literature relative to caliche materials as a medium for treatment and disposal of wastewater has been conducted. It was ...
-
(Texas Water Resources Institute, 2016-02)The “Carters Creek Total Maximum Daily Load Implementation” project was developed to provide additional information to watershed stakeholders regarding the spatial and temporal distribution of E. coli concentrations in ...
-
Carters Creek Total Maximum Daily Load Implementation Project: Education and Outreach Report: Task 6 (Texas Water Resources Institute, 2016-01)Communication is the cornerstone of all effective efforts, and water quality projects are no exception. Open and effective lines of communication were established through this project with the purpose of conveying project ...
-
(Texas Water Resources Institute, 2016-01)Developing a clearer understanding of the spatial and temporal variability in E. coli concentrations monitored throughout the watershed and establishing a clear baseline of current E. coli loads at a sub-watershed scale ...
-
(Texas Water Resources Institute, 2016-01)The Carters Creek watershed is a tributary of the Navasota River and covers an area of about 56.9 square miles in Brazos County. Approximately 57% of this area is urbanized (Figure 1), primarily by the cities of Bryan and ...
