Kasmarek, M.C. and Ramage, J.K., 2017, Water-Level Measurement Data, Water-Level Altitude and Long-term Water-Level Altitude Change Contours (2017) in the Chicot, Evangeline, and Jasper Aquifers, Houston-Galveston Region, Texas: U.S. Geological Survey data release, https://doi.org/10.5066/F77S7M18.
Most of the land-surface subsidence in the Houston-Galveston region, Texas, occurs as a direct result of groundwater withdrawals for municipal supply, commercial and industrial use, and irrigation that depressured and dewatered the Chicot, Evangeline, and Jasper aquifers, thereby causing compaction of the aquifer sediments, mostly in the fine-grained silt and clay layers (Gabrysch, 1977). This dataset was created by the U.S. Geological Survey 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.
