Groundwater-Level Altitudes and Long-Term Groundwater-Level Changes in the Chicot and Evangeline (Undifferentiated) and Jasper Aquifers, Greater Houston area, Texas, 2021

Metadata Updated: October 29, 2023

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot and Evangeline aquifers (undifferentiated), and Jasper aquifer in the greater Houston area, Texas. This dataset shows current‐year (2021) groundwater‐level altitudes for each aquifer, 1–year (2020–21), 5‐year (2016–21) groundwater‐level changes for each aquifer, long‐term (1990–2021 and 1977–2021) groundwater‐level changes for the Chicot and Evangeline aquifers (undifferentiated), and long‐term (2000–2021) groundwater‐level change for the Jasper aquifer. The groundwater‐level measurements from which the dataset was built are stored in the USGS National Water Information System (NWIS) (http://doi.org/10.5066/F7P55KJN) and are accessible through the NWIS Web Interface. In 2021, measured groundwater-level-altitudes for the Chicot and Evangeline aquifers (undifferentiated) ranged from about 295 feet (ft) below the North American Vertical Datum of 1988 to about 214 ft above datum. Measured groundwater-level-altitudes for Jasper aquifer ranged from about 235 ft below datum to about 272 ft above datum. This dataset was created by the USGS to provide resource managers, public officials, researchers, and the general public with ready access to accurate, impartial, scientific information regarding groundwater‐level changes and altitudes in Harris, Galveston, Fort Bend, Montgomery, Brazoria, Chambers, Grimes, Liberty, San Jacinto, Walker, and Waller Counties, Texas.
