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.). Last week, some of our Board of Directors and District Staff visited areas that have historically been affected by subsidence and toured important projects that have been implemented to prevent further subsidence in the Houston area. 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. Visit smarteraboutwater.org for water conservation resources to help homeowners, businesses, and the community. Harris County MUD 501 purchases its water supply from Harris County Municipal Utility District 500, which purchases surface water from the Authority. Managing how groundwater resources are used is key to controlling subsidence. %N_yuJlv\DxD"`UIci+QV8F,P"iRNd[U]4#8T&2m4=oCgq! Since it is not a GCD, HGSD participates in the activities of GMA 14 as an inter-local participant. below the land surface due to groundwater withdrawals. Up to 2020, regional water-level altitude maps were created by manually interpolating contours of December 1, 2020. 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. Brazoria County Groundwater Conservation District, Lone Star Groundwater Conservation District. The cumulative compaction in the Chicot and Evangeline aquifers are measured at 13 extensometer stations in the 11-county area. (4) "Groundwater" means water located beneath the earth's surface. Pay Your Water Bill To learn how to submit your report online, check out our instructional video! Now on its fifth iteration since 1976, the plan describes the different regulatory areas throughout the district, defines groundwater withdrawal limits for each area, and provides guidelines for permitting. groundwater withdrawal on land subsidence in the Houston-Galveston region of Texas. Evaluation of projected population and future water demands, Development of subsidence models to simulate future subsidence based on projected water demands, Measurement of annual water-level to show the impact of conversion requirements on the water-level in the aquifer, Assessment of alternative water supplies including brackish groundwater use and aquifer storage and recovery. In 2021, kriging, a geostatistical interpolation method, was Harris-Galveston Subsidence Districts main mechanism of regulation is through its regulatory plan, with requirements laid out in the districts enabling legislation. EXECUTIVE SUMMARY: The Fort Bend Subsidence District (FBSD) revised its District Regulatory Plan (DRP) in 2013 based on population and water demand projections, which were developed as part of a Regional Groundwater Update Project (RGUP) completed in 2013. region since the early 1900s. 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. 1700 North Congress Avenue, Austin, TX 78701TEL: 512-463-7847 / FAX: 512-475-2053, Panhandle Groundwater Conservation District, Panola County Groundwater Conservation District, Pecan Valley Groundwater Conservation District, Permian Basin Underground Water Conservation District, Pineywoods Groundwater Conservation District, Plateau Underground Water Conservation and Supply District, Post Oak Savannah Groundwater Conservation District, Prairielands Groundwater Conservation District, Presidio County Underground Water Conservation District, Real-Edwards Conservation and Reclamation District, Red River Groundwater Conservation District, Red Sands Groundwater Conservation District, Reeves County Groundwater Conservation District, Refugio Groundwater Conservation District, Rolling Plains Groundwater Conservation District, Rusk County Groundwater Conservation District, San Patricio County Groundwater Conservation District, Sandy Land Underground Water Conservation District, Santa Rita Underground Water Conservation District, Saratoga Underground Water Conservation District, South Plains Underground Water Conservation District, Southeast Texas Groundwater Conservation District, Southern Trinity Groundwater Conservation District, Southwestern Travis County Groundwater Conservation District, Starr County Groundwater Conservation District, Sterling County Underground Water Conservation District, Sutton County Underground Water Conservation District, Terrell County Groundwater Conservation District, Trinity Glen Rose Groundwater Conservation District, Upper Trinity Groundwater Conservation District, Uvalde County Underground Water Conservation District, Victoria County Groundwater Conservation District, Wes-Tex Groundwater Conservation District, Wintergarden Groundwater Conservation District, Asset Management Program for Small Systems, State Water Implementation Fund for Texas (SWIFT), Guidance & References for Online Loan Application, State Water Implementation Fund for Texas, 6th Planning Cycle Information (2026 RWPs), 2021 Regional Water Plans & Previous Plans, Regional Water Planning Data Entry Application (RWP22) Training, District Information (O-Z and Other Districts), Extended Naturalize Flow and Reservoir Evaporation, Flood Planning Useful Links and Resources, Drought Response and Financial Assistance, Water Conservation Plan ~ Utility Profile, Historical Water Loss Audit and Conservation Annual Report Data, Industrial, Commercial & Institutional (ICI), Permanent Rules - Effective January 1, 2019, Brackish Resources Aquifer Characterization System, Notice of Nondiscrimination and Reasonable Accommodation, Texas Natural Resources Information System (TNRIS), Texas Water Infrastructure Coordination Committee (TWICC), District was created by Petition to the Texas State Board of Water Engineers, 1955, (formerly Martin County Underground Water Conservation District), (formerly Haskell/Knox County Underground Water Conservation District). water for municipal supply, commercial and industrial use, and irrigation in the Houston-Galveston Groundwater withdrawn from the Chicot-Evangeline and Jasper aquifers has been the primary source of Water-level altitudes 2016 and water-level changes in the Chicot - USGS According to a 2017 USGS report, Water levels in the southeastern parts of the study area in the Chicot and Evangeline aquifers have generally continued to rise since 1977, while water levels in the northern and western parts of Harris County and Southern Montgomery County have continued to decline. %%EOF This position supports both Harris-Galveston Subsidence District and Fort Bend Subsidence District as the water conservation subject matter expert providing administrative, technical, and educational information on water conservation, water science, and other natural science topics to a broad audience.
