This report was prepared in cooperation with the Fort Bend Subsidence District, and presents maps of the approximate altitude of water levels in wells completed in the Chicot and Evangeline aquifers (figs. -2) during January-February 1991 in Fort Bend County and adjacent areas, Texas. These approximate altitudes of water levels give an approximate depth to potable ground water within Fort Bend County and can be used to estimate depth for installing well pumps.
