This report consists of: (1) Four maps that present data on water-level changes during 1977-82 and 1981-82 in the Chicot and Evangeline aquifers and (2) one set of graphs that present data on the compaction of subsurface materials for 1973-82. During these periods, ground-water pumping decreased in Galveston County and eastern Harris County and increased in northern and western Harris County. (USGS)
