By 1977, an extensive groundwater well-monitoring network had been established and the USGS had collected water-level data that were used to create the first published water-level altitude maps of the Chicot and Evangeline aquifers in the Houston-Galveston region. This report, prepared by the U.S. Geological Survey 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, is one in an annual series of reports depicting water-level altitudes and water . In addition HGSD provides water conservation, education, and outreach programs to underscore the importance of water conservation in the community. SMU is developing subsidence maps from 1992 to 2023 by integrating data obtained from multi-temporal Interferometric Synthetic Aperture Radar (InSAR), a remote sensing technique using data collected from orbiting satellites, to quantitatively evaluate subsidence over specific periods of time across the region. As the Houston Chronicle reported, Over the years, Texas lawmakers enacted bills to create subsidence or water conservation districts in counties that include Harris, Fort Bend, Montgomery and Galveston.
