Abstract

Rapid urban development in the Austin metropolitan area, Texas, is causing concern about increasing peak discharges from stream runoff and the degradation of the quality of water in receiving streams, lakes, and aquifers. In an attempt to reduce peak discharges and improve water quality, runoff controls are being required in certain watersheds. This report summarizes the precipitation, streamflow, and water quality data collected from September 1982 to September 1984 upstream and downstream from runoff controls at two locations, and presents the effects of these runoff controls on streamflow and the quality of runoff water. The runoff controls at the two locations are a detention and filtering pond near Barton Creek Square Shopping Center, a large shopping center located southwest of downtown Austin, and a grass-covered swale control in the Alta Vista Planned Unit Development, a multiple-family housing area. Data indicate that as a result of the Barton Creek Square Shopping Center detention and filtering pond, peak discharges were reduced and peak concentration and loads of most of the analyzed constituents were reduced. However, the grass-covered swale control had little effect on reducing the peak discharges and peak concentrations at the Alta Vista Planned Unit Development. (USGS)
