Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1977-90 and 1989-90, and measured compaction, 1973-December 1989, in the Houston-Galveston region, Texas

This report is one in a series of reports that depict water-level changes since 1977 and compaction of subsurface material since 1973. The report was prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, and presents approximate water-level changes in wells in the Chicot and Evangeline aquifers, 1977-90 and 1989-90 (figs. 1-4), and measured compaction, 1973-December 1989 (figs. 5 and 6), in the Houston-Galveston region.
