This report, prepared in cooperation with the Fort Bend Subsidence District, presents maps for the Chicot and Evangeline aquifers in Fort Bend County and adjacent areas showing the approximate water-level altitudes in wells in 1990 (figs. 1, 2). The most recent previously published water-level-altitude maps (and water-level-change maps) for the two aquifers are by Coplin and others (1997). The earliest water-level-altitude maps (and water-level-change maps) for the Chicot aquifer are by Wesselman (1972). The first maps of water-level altitudes (and water-level changes) for Chicot and Evangeline aquifers are by Locke (1990).
