Water-Level Altitudes and Water-Level Changes (2016/2017)

The U.S. Geological Survey, in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Brazoria County Groundwater Conservation District, and Lone Star Groundwater Conservation District, collects, processes, and interprets groundwater-level and aquifer-sediment-compaction data to understand the effects of groundwater withdrawal on land subsidence in the Houston-Galveston region, Texas.

The following reports provide recent datasets of water-level changes and approximate water-level altitudes in the Chicot, Evangeline, and Jasper aquifers in the Houston-Galveston region, Texas.

The water-level measurements in the dataset are built upon and stored in the National Water Information System: web interface, groundwater information, and field measurements website located here: http://dx.doi.org/10.5066/F7P55KJN and the subsidence viewer located here: https://txpub.usgs.gov/houston_subsidence/viewer/index.html. These sites provide a publicly available, searchable, online database of water information.
