The Geological Survey 's water resource monitoring program in the Georgetown area, Texas for water year 1988 consisted of a network of about 65 observation wells measured in the winter and summer, and a network of 10 streamflow-monitoring sites where flow was measured either continually or in the winter and summer. Data measurements included flow or water levels, specific conductance, temperature, and pH. These data show that the streamflow was substantially less in water year 1988 than in the previous 2 years. Regional changes in groundwater levels between the winters of 1987 and 1988 show slight declines (2 to 6 ft) in the northeast part of the study area while moderate declines (6 to 10 ft) were common in the southeast part. The most severe declines (greater than 10 ft) occurred in the corridor between Round Rock and Georgetown. A pattern of greater declines (moderate to severe) than in the surrounding area occurred north of Georgetown. (USGS)
