The model will simulate the impacts of groundwater use on aquifer water levels and land subsidence throughout the region and will be used to evaluate regulatory scenarios of interest to both subsidence districts. The RGUP was jointly supported by the Harris-Galveston Subsidence District, the Fort Bend Subsidence District, and the Lone Star Groundwater Conservation District. These efforts have identified and documented the susceptibility of land surface subsidence due to the production of groundwater in the Chicot and Evangeline aquifers. Annual Pumpage Reports are due by January 31, 2023. When expanded it provides a list of search options that will switch the search inputs to match the current selection. reduce groundwater withdrawals in Harris and Galveston Counties. 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.).

If you are a leader with a passion for executing projects that improve our local communities, check out this opportunity! From USGS well monitoring over decades they are able to show that once subsidence districts are created, groundwater levels rise significantly, thereby decreasing subsidence issues in their districts. When we pump large amounts of water from the aquifers beneath us, we pull water out of the many layers of clay, which causes the clay to compact, lowering the elevation of the land above. The District has taken a reasonable approach to groundwater regulation in order to minimize subsidence within its regulatory areas. Get the latest news and updates from the Harris-Galveston Subsidence District. 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.

Surface water shift through $381M Luce Bayou Project keeps homes limits 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. You can view research studies, model information, and interactive maps under the Science & Research tab of the HGSD website. Extensometers and Subsidence.

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. 1989: Established by the Texas State Legislature. Fort
This model will provide valuable information to inform the regulatory decision-making of the HGSD and FBSD. interprets groundwater-level and aquifer-sediment-compaction data to understand the effects of
The Harris-Galveston Subsidence District (HGSD) is a special purpose district created by the Texas Legislature in 1975. (3) "District" means the Harris-Galveston Subsidence District. Water-level altitude contours, wells, and compaction data have been combined in an interactive map that allows users to view annual water-level altitudes from 1977 through the present, water-level changes over time, and historical time series of compaction data. Water demands were projected for individual water supply systems based on average per capita demands observed from 2000 to 2008. City of Houston, TX: Boards - Granicus The development of brackish groundwater resources has become a more common water management strategy in the State of Texas. 1 0 obj accurate land-surface altitude data available at the time of publication were used in the creation of

This district was created because area residents and local governments were becoming increasingly alarmed by subsidences continued impact on the regions economic growth and quality of life. Click here to read our blog about how it could be addressed with a new USGS subsidence mapping tool. We are hiring a Deputy General Manager Fort Bend Operations to join our executive leadership team. The District was created to provide for the regulation of groundwater withdrawal. The Lone Star Groundwater Conservation District in 2012 purchased six Periodically Accessible Monitors (PAMs), which are specifically designed to detect subsidence. In reaction to the subsidence issues across the Houston-Galveston region, the Texas Legislature established the first subsidence district in 1975 to reduce or minimize further groundwater subsidence in their area.

You can also view water levels by visiting the Lone Star Static Well Level Monitoring Network Map. Vision, Mission and Stategic Goals of the Harris-Galveston Subsidence District. The U.S. Geological Survey (USGS) prepared this dataset in cooperation with the HarrisGalveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District. 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. The data is temporarily stored in an on-site monitor and periodically uploaded to computers at the Harris Galveston Subsidence District. Harris-Galveston Subsidence District, Fort Bend Subsidence District, and the USGS are working closely with the Texas Water Development Board to ensure that the GULF-2023 model will be available as a regional tool for GMA 14 to provide the best science and planning information for the region. Alternative water sources, like treated surface water, prevents excessive groundwater pumping, thereby minimizing subsidence.
