This dataset is part of an annual project that measures groundwater-levels and calculates long-term groundwater-level changes in the Chicot, Evangeline and Jasper aquifers located within Harris, Galveston, Fort Bend, Montgomery, Brazoria, Chambers, Grimes, Liberty, San Jacinto, Walker, and Waller Counties, Texas. The data were obtained to assess annual groundwater-level changes related to groundwater withdrawal and land-surface subsidence in the Houston-Galveston region, Texas. Land-surface subsidence occurs as a direct result of groundwater withdrawals for municipal supply, commercial and industrial use, and irrigation that depressures and dewaters the Chicot, Evangeline, and Jasper aquifers, thereby causing compaction of the aquifer sediments (Gabrysch, 1979). This dataset was created to provide resource managers, public officials, researchers, and the general public with ready access to accurate, impartial, scientific information regarding groundwater‐level measurements.
