Interactive map of groundwater levels and subsidence in the Houston-Galveston area

The U.S. Geological Survey provides an interactive map that allows users to view changes in groundwater levels and associated land subsidence since 1977 in the Houston-Galveston area.

The map uses annual data from over 800 wells, and shows changes in water levels in three major aquifers in the region: the Chicot, Evangeline, and Jasper aquifers.
