Lower Colorado River Authority

Lower Colorado River Authority

The Lower Colorado River Authority (LCRA) project area entails 10,160 sq. km (3,925 sq. mile) of the lower Colorado River beginning immediately below Austin, Texas. Assessment of nonpoint source pollutants is emphasized in this project, especially those originating from cropland. NRCS modeling, in conjunction with LCRA’s collection of runoff samples, was done in an attempt to determine what effects BMPs can have on sediment, nutrient and chemical loads in cropland runoff.
