Want to learn more about how subsidence has impacted this region? The districts mission is to control land subsidence and manage groundwater resources through regulation, conservation, and coordination with suppliers of alternative water sources to assure an adequate quantity and quality of water for the future. Since 1990, the Fort Bend Subsidence District has regulated groundwater withdrawals and monitored subsidence in Fort Bend county. 1 of 11. Population projections were developed at the census block level for each decade from 2010 to 2070 using the 2010 U.S. Census as a population baseline. 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. Activities In the Houston-Galveston region, land subsidence is caused by compaction of fine-grained aquifer sediments (silts and clays) below the land surface due to groundwater withdrawals. endstream endobj 190 0 obj <>stream HGSD has the goal of reducing the area to 20% reliance on groundwater by 2035 and managing water to promote .

This study, spawned from their original research that showed subsidence in southern Montgomery County was caused by exploitation of the Jasper aquifer, will investigate the combined effects of climate changes on coastal subsidence to enhance understanding of the deformation process. HGSD has the goal of reducing the area to 20% reliance on groundwater by 2035 and managing water to promote . The reduction in pumpage has resulted in the increase of water- level in the aquifer system in those areas and a reduction in subsidence rates. The District was created to provide for the regulation of groundwater withdrawal. 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. endobj Click for water-level altitude and regional water-level change contour map can be found in the individual year Newsletters A focus of these scenarios will be on the variables that minimize subsidence in the future while accounting for the availability of alternative water supplies. 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. For keyboard navigation: First, use Arrow Keys to navigate up and down the districts.

Reduces the ability to store water in an aquifer. Since the creation of the GMA, HGSD has provided information, research, and financial support to the GMA process. The new intake pump station will draw water from Lake Houston and, upon completion of the water treatment facility, will be able to provide 320 million gallons of treated water per day. This is because in addition to sinking land elevations, subsidence contributes to flooding, inundation, or overflow of areas within the district, including rising waters resulting from storms or hurricanes. We are hiring a Deputy General Manager Fort Bend Operations to join our executive leadership team. levels rise, compacted sediments and the associated land-surface lowering would remain as-is.

This report, prepared by the U.S. Geological Survey in cooperation with the Harris-Galveston Coastal Subsidence District, documents and refines the locations of principal faults mapped in the Houston, Texas, metropolitan area in previous studies. <> The District was created to provide for the regulation of groundwater withdrawal throughout Harris and Galveston counties for the purpose of preventing land subsidence, which leads to increased flooding. Next, we traveled to the infamous Brownwood Subdivision, which was abandoned due to substantial subsidence in the 1980s. 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. 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.
