Kasmarek, M.C., and Ramage, J.K., 2016, Water-Level Measurement Data Collected during 2015-2016 and Approximate Long-term Water-Level Altitude Changes of Wells Screened in the Chicot, Evangeline, and Jasper Aquifers, Houston-Galveston Region, Texas: U.S. Geological Survey data release, https://doi.org/10.5066/F77H1GP3.
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. This dataset, part of annual series of reports, was created by 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, 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, Waller Counties, Texas.
