Routine water quality monitoring indicates that several waterbodies in the Proctor Lake watershed (Duncan Creek, Rush-Copperas Creek, Sabana River, Sweetwater Creek, and Leon River below Leon Reservoir) do not meet water quality standards for recreation use because of elevated concentrations of bacteria. Leon River below Leon Reservoir is also considered impaired for aquatic life use due to depressed dissolved oxygen concentrations. Several use concerns due to depressed dissolved oxygen, elevated concentrations of chlorophyll-a, bacteria, and nitrates also exist in the watershed. With water quality impairments comes a need to plan and implement actions that restore water quality and ensure safe and healthy water.
To meet this need, the Texas Water Resources Institute, in partnership with the Texas State Soil and Water Conservation Board, is working with local stakeholders to characterize the watershed by identifying sources of pollution in the watershed contributing to water quality impairments and related concerns.
This report describes the analysis of existing data and information on water quality impairments and pollutant loading in the watershed. Existing data and information are used to the extent possible to characterize water quality conditions, watershed characteristics, and potential sources of pollution contributing to water quality impairments and concerns.
