The Harris-Galveston Subsidence District is a special purpose district created by the Texas Legislature in 1975 to regulate groundwater withdrawal throughout Harris and Galveston counties in order to prevent land subsidence.
Subsidence Lone Star Groundwater Conservation District 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. 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. This is accomplished through the careful regulation of groundwater withdrawals, working in collaboration with surface water suppliers.

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. Search form lists all water wells with a HGSD permit in a given area.

She joins Harris County from the Harris-Galveston Subsidence District, where she has served as Deputy General Manager for the past 3 years and oversaw the District's Regulatory Planning, Scientific Research, and Water Conservation Programs. The RGUP originally started in 2010 as the Harris-Galveston Subsidence District (HGSD) 1999 Regulatory Plan Update, but due to its benefits to other regional groundwater regulatory agencies, the Fort Bend Subsidence District (FBSD) and the Lone Star Groundwater Conservation District (LSGCD) joined the collaborative effort in 2010.The primary benefit of collaboration between these three entities is that each of them could use the RGUP to vet their existing regulatory plans using updated population/water demand data and groundwater modeling capability, and in the case of HGSD and FBSD, investigate the physical effects of changing their existing regulatory plans to accommodate the practical realities facing their stakeholders while successfully completing the Districts mission objectives.

USGS TXWSC - Coastal Science When we pump large amounts of groundwater from the aquifers beneath us, we pull water out of the many layers of clay, which can cause the clay to compact. 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. 18-396 passed on March 28, 2018, the Board of Directors held the Annual Groundwater Hearing beginning at 2:30 p.m. on May 23, 2018. region since the early 1900s.

Managing how groundwater resources are used is key to controlling subsidence. https://lnkd.in/gkwTtcAZ. 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. Brazoria County Groundwater Conservation District . 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. Alters the flow of creeks and bayous which may increase the frequency and severity of flooding. 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 Harris-Galveston Subsidence District (District) is a special purpose district created by the Texas Legislature in 1975. 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. historical year or as the difference in water-level altitude at each well for the water-level data
The Harris-Galveston Coastal Subsidence District has required reduced groundwater use to slow or stop subsidence (sinking of ground level) in Harris and Galveston Counties. Though subsidence rates are moderate in Fort Bend county, the continued heavy dependence of groundwater use may result in increased subsidence and associated impacts such as flooding and infrastructure damage.
