Abstract

Precipitation, streamflow, and base-flow data were analyzed for December 1974 through March 1977 as a part of the Edwards-Trinity Regional Aquifer-System Analysis in west-central Texas. The period of record analyzed corresponds to the calibrating period of a digital groundwater-flow model of the aquifer system currently (1988) being developed. Precipitation at individual stations ranged from 6 to 45 in/yr. Precipitation normally (1951-80) ranged from 10 to 32 in/year from east to west in the study area. Precipitation was near normal over most of the area and above normal in the southeastern part of the study area. Streamflow ranged from less than 1 in/year in the western part of the study area to 13 in/yr in the southeastern part. Streamflow was 8 in/yr above normal in the southeast. Base flow ranged from less than 0.1 in/yr in the western part of the study area to 6 in/yr in the southeastern part. (USGS)
