The cumulative compaction in the Chicot and Evangeline aquifers are measured at 13 extensometer stations in the 11-county area. 2019 Annual Groundwater Report Appendix A, 2019 Annual Groundwater Report Appendix B, 2019 Annual Groundwater Report Appendix C. Pursuant to Fort Bend Subsidence District (the District or FBSD) Resolution No. established the Fort Bend Subsidence District and two groundwater conservation districts: Lone Star 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. Pay Your Water Bill 1985: Divided into 8 regulatory areas by amount of groundwater reduction needed. as the difference in water-level altitude at each well for the water-level data collection year and the They have successfully slowed-down land subsidence, decreased flood risks, and overall maintained the viability of the area. In cooperation with Click here to view information and publications from USGS about groundwater and subsidence on the Texas Gulf Coast. The variables to be explored include: Since the District was created in 1975, our focus has been on preventing subsidence through reasonable regulation of groundwater use, says Mike Turco, General Manager of HGSD, our commitment to cutting-edge research and consistent investment in the highest-quality data collection, with agencies like the USGS, has provided a firm scientific basis for a successful regulatory plan. The new GULF-2023 model will be the latest product in a large body of scientific activities initiated by HGSD. 186 0 obj <> endobj 1989: Established by the Texas State Legislature.

Request for Qualifications and other important information related to doing business with the Harris-Galveston Subsidence District. Since 1836, groundwater withdrawals have caused about 3,200 square miles of the Houston-Galveston area to subside (or sink) more than a foot, with some areas subsiding as much as 12 to 13 feet. Neighbors. Groundwater Conservation District and, most recently, Brazoria County Groundwater Conservation District Next, we traveled to the infamous Brownwood Subdivision, which was abandoned due to substantial subsidence in the 1980s. The primary aquifers in the Gulf Coast aquifer system in the Houston-Galveston region are the After collecting and evaluating groundwater-level data for quality control, data are incorporated into a }D?|=X'W|pqe'p]x/ Then, use either Enter or Space key to open the selected district. This district was created because area . HGSD is divided into three regulatory areas stretching from High Island and Galveston upwards to Hempstead, TX. People who live in the lower lying coastal areas (i.e., lower elevations and flatter topography) have much more reason to be concerned with subsidence than those who reside further inland in areas of higher elevations with more topographic relief. In order to evaluate the performance of the projection methodology which informed the 2013 DRP, the short-term projections from the RGUP have been evaluated against recent estimates of population and water demand from multiple sources at various geographic scales.

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 HGSD provides water conservation, education, and outreach programs to underscore the importance of water conservation in the community. 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 Subsidence District has adopted regulations requiring reduction of groundwater withdrawals through conversion to alternate source water (e.g., surface water) in certain areas within the Subsidence Districts jurisdiction, including the land within Harris County MUD 501. Harris-Galveston Subsidence District in Boydton, VA Expand search. Some natural land subsidence also occurs over long periods of time, due to natural settling.
