Vision, Mission and Stategic Goals of the Harris-Galveston Subsidence District. The Houston area's two subsidence districts the Harris-Galveston Subsidence District, HGSD, and the Fort Bend Subsidence District have worked to monitor subsidence and mitigate it through a variety of water management efforts. Regular, precise, automated readings are taken of the elevation of the ground at locations throughout the county.

The Lone Star GCD has studied the Gulf Coast Aquifer for a decade and confirmed the reports of many local water suppliers, which state that water levels in the countys aquifers have declined at an alarming rate as a result of deficit pumping. It has since been turned into the Baytown Nature Center. In cooperation with 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 .

For almost 50 years, they have been collecting, storing, and sharing data on groundwater abstraction and resulting surface lowering. Subsidence regulation districts and their creation timeline The Harris-Galveston Coastal Subsidence District. The Harris-Galveston Subsidence District, in cooperation with the Fort Bend Subsidence District, the Brazoria County Groundwater Conservation District, the Lone Star Groundwater Conservation District, the University of Houston, and the Brazosport Water Authority maintains a subsidence monitoring network that is constantly evolving and requires consistent investment. In Houston, land subsidence is caused by the withdrawal of groundwater. This effort has published aquifer levels and subsidence data since 1975 and is a great example of what can be accomplished through sustained collaboration between, city, county, regional, and federal partners. The U.S. Geological Survey prepared this dataset in cooperation with the HarrisGalveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District. 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, has produced this dataset of water-level changes and approximate water-level altitudes in the Chicot, Evangeline, and Jasper aquifers in the Houston-Galveston region, Texas.

In addition to regulation, the district also conducts research to enhance its understanding of the Upper Gulf Coast aquifer to better manage subsidence. Subsidence is known to have occurred in the southern part of Montgomery County based on monitoring and long-term surveying of land surface. publication. After successfully implementing InSAR mapping in the Houston-Galveston region in 2019, this new project will harness the complimentary capabilities of the Subsidence Districts subsidence monitoring network and SAR imagery to develop these historical deformation maps.
