RRC Nonpoint Source Grant Project for the Colorado River Downstream of Spence Reservoir

The United States Environmental Protection Agency (EPA) has awarded a nonpoint source grant to the Railroad Commission of Texas for the investigation of the nature and extent of known salinity contamination in the Colorado River downstream of the E.V. Spence Reservoir. The Texas Commission on Environmental Quality (TCEQ) has placed Segment 1426 of the Upper Colorado River, downstream of the E.V. Spence Reservoir, on the state's 303(d) list because it does not meet water quality standards. The RRC will use this grant to conduct various activities to reduce the high salinity that contributes to water quality degradation.
