Water levels from wells completed in the Chicot and Evangeline aquifers were used to construct maps showing approximate changes in water levels during 1977-94 and 1993-94. Compaction data from 12 borehole extensometers equipped with compaction monitors at 11 sites during 1973-93 also are presented.
