Background and Goals

The E.V. Spence Reservoir is located in Coke County. With a surface area of 15,893 acres, it is an important source of water for more than 300,000 people in surrounding cities, including Big Spring, Odessa, Midland, and San Angelo. Additionally, the reservoir serves mining and industrial uses, and it is a popular destination for recreational fishermen. Water quality testing found that excessive levels of sulfate and total dissolved solids (salinity) are affecting the lake and its use for drinking water. The goal of this project is to reduce point and nonpoint sources of these pollutants to restore and maintain water quality standards for the reservoir.
