Water-level altitudes 2000, water-level changes 1977-2000 and 1999-2000 and compaction 1973-99 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas

January 1, 2001

This report is one in an annual series of reports that depicts water-level altitudes and water-level changes since 1977 and compaction since 1973 in the Chicot and Evangeline aquifers in the Houston-Galveston region, Texas. The report, prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, presents maps for the Chicot and Evangeline aquifers showing the approximate water-level altitudes in wells in 2000 and approximate water-level changes in wells from 1977 to 2000 and from 1999 to 2000, a map showing extensometer site locations, and graphs showing measured compaction of subsurface material at selected sites from 1973 to 1999. The most recent previously published water-level-altitude maps and water-level-change maps for the two aquifers in the region are by Coplin and other (1999). The Houston-Galveston region comprises Harris and Galveston Counties and adjacent parts of Brazoria, Fort Bend, Waller, Montgomery, Liberty, and Chambers Counties.
