    • Water-Level Altitude and Long-term Water-Level Altitude Change Contours (2017) in the Chicot, Evangeline, and Jasper Aquifers in the Houston-Galveston Region, Texas.

    Metadata Updated: September 24, 2025

    The U.S. Geological Survey in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District has produced this dataset of water‐level altitudes and water‐level altitude changes in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas. This dataset shows current‐year (2017) water‐level altitudes for each aquifer, 5‐year (2012‐17) water‐level changes for each aquifer, long‐term (1990‐2017 and 1977‐2017) water‐level changes for the Chicot and Evangeline aquifers, and long‐term (2000‐2017) water‐level change for the Jasper aquifer. The water‐level measurements from which the dataset were built are stored in the National Water Information System: Web Interface, groundwater information, field measurements website located here: http://dx.doi.org/10.5066/F7P55KJN This site is a publicly available, searchable, online database of water information.
