The GULF-2023 model is a new $588,000 endeavor jointly funded by the HGSD and FBSD, in cooperation with USGS. This study provides a basis for future research on subsidence in the Districts area and can inform water managers and planners in the Houston area on the availability of brackish groundwater resources. The District office will be closed on Monday, February 20, 2023, in observance of Presidents Day and will reopen during regular business hours on Tuesday, February 21, 2023.

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.

The Lone Star Groundwater Conservation District in 2012 purchased six Periodically Accessible Monitors (PAMs), which are specifically designed to detect subsidence. Types of research sponsored by the District include: Each year the Board of Directors holds a public hearing for the purpose of taking testimony concerning the effects of groundwater withdrawals on the subsidence of land within the District during the preceding year. The live data from the two older PAM units may be viewed by clicking on the Subsidence Monitoring Network Map (If you have Google Earth installed on your computer, simply click on the .kml file, and Google Earth will automatically open, showing you the network map.). Harris-Galveston Subsidence District (coastal Texas, U.S.A.) is worldwide one of the frontrunners in subsidence prevention, by regulating, registering, and permitting the withdrawal of groundwater from deep aquifers. Both surface water and groundwater rates were reduced by $0.50 per 1,000 gallons. 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. larger image.
