Summary

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 (2022) groundwater‐level altitudes for each aquifer as well as 1–year (2021–22), and 5‐year (2017–22) groundwater‐level changes for each aquifer, long‐term (1990–2022 and 1977–2022) groundwater‐level changes for the Chicot and Evangeline aquifers (undifferentiated), [...]

Purpose

Most of the land-surface subsidence in the greater Houston area, Texas, occurs as a direct result of groundwater withdrawals for municipal supply, commercial and industrial use, and irrigation that depressurizes and dewaters the Chicot, Evangeline, and Jasper aquifers, thereby causing compaction of the aquifer sediments, mostly in the fine-grained silt and clay layers (Gabrysch, 1979). 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.
