Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1977-89 and 1988-89, and measured compaction, 1973-89, in the Houston-Galveston region, Texas

This report presents data on water-level changes in the Chinot and Evangeline aquifers during 1977-89 and 1988-89 and data on measured compaction during 1973-89.

Measurements of water level in 307 wells were used to construct the maps showing water-level changes. Compaction data were obtained from 12 wells equipped with compaction monitors at 11 sites.
