Harris-Galveston Subsidence District Joins the Winners' Circle. The goal was to keep the region elevated by developing ways to reduce groundwater consumption.. While some of the duties and goals are similar to those of groundwater conservation districts, Harris-Galveston Subsidence District (HGSD) is not governed by Chapter 36 of the Texas Water Code. 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. Groundwater withdrawn from the Chicot-Evangeline and Jasper aquifers has been the primary source of Annual Pumpage Reports are due by January 31, 2023.

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. This dataset shows current-year (2015-2016) water-level changes for each aquifer, 5-year (2011-2016) water-level changes for each aquifer, long-term (1990-2016 and 1977-2016) water-level changes for the Chicot and Evangeline aquifers, and long-term (2000-2016) water-level changes for the Jasper aquifer. %PDF-1.3 Since its creation, subsidence rates have slowed greatly.

Based on this analysis, recommendations have been developed to refine the methodology used in the next regional update project to further improve the next iteration of the regulatory plan. Interpolated modeled water-level altitude surfaces were only used to compute differences when wells were The Texas Alliance of Groundwater Districts supports Texas groundwater conservation districts and their efforts to conserve, preserve, and protect Texas groundwater. Some natural land subsidence also occurs over long periods of time, due to natural settling. (4) "Groundwater" means water located beneath the earth's surface.

Significant brackish groundwater resources exist within the Gulf Coast Aquifer System near Houston, Texas in Harris, Galveston, Fort Bend, and surrounding counties. Next, we traveled to the infamous Brownwood Subdivision, which was abandoned due to substantial subsidence in the 1980s. 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. 9 were here. Harris-Galveston Subsidence District. 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.

Alters the flow of creeks and bayous which may increase the frequency and severity of flooding. Regional water-level change maps were constructed by interpreting the compiled water-level altitude data 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. While some areas in Houston have significantly reduced their groundwater pumping (particularly with the creation of subsidence and groundwater districts, whose purpose is to regulate groundwater pumping), subsidence still remains a threat for the region. A resident of the Houston area since 2011, Vanessa began working in community . People who live in the lower lying coastal areas (i.e., lower elevations and flatter topography) have much more reason to be concerned with subsidence than those who reside further inland in areas of higher elevations with more topographic relief. 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. 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.

These units operate in conjunction with the two that have been monitoring land levels in Montgomery County for more than 10 years. The purpose of this report is to summarize the results of the Regional Groundwater Update Project (RGUP). . The Science and Research Plan is designed to be a dynamic document with the intention to provide clarity to the strategic direction of the District and guidance to future science and research priorities in support of the District Regulatory Plan. Subsequent to establishing the Harris-Galveston Subsidence District, the Texas State Legislature Establishes policy regarding groundwater regulation withdrawals to control subsidence. Since the creation of the GMA, HGSD has provided information, research, and financial support to the GMA process. 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. These efforts have identified and . Learn about the history of the Harris-Galveston Subsidence District. 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. 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 results of this study confirm the potential for compaction in the Jasper aquifer and subsidence to occur from brackish groundwater development particularly in up-dip areas near where the Jas-per is being used for freshwater supply. In order to evaluate the performance of the projection methodology which informed the 2013 DRP, the short-term projections from the RGUP have been evaluated against recent estimates of population and water demand from multiple sources at various geographic scales. Star Groundwater Conservation District. Creation year: 1975 (64th Texas Legislature). 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. USGS measures groundwater levels in over 700 wells in an 11-county area annually in the 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. 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. The District provides for the regulation of groundwater withdrawal throughout Harris and Galveston counties for the purpose of preventing land subsidence, which leads to increased flooding. 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. For almost 50 years, they have been collecting, storing, and sharing data on groundwater abstraction and resulting surface lowering. Purpose: To manage groundwater withdrawal and enforce groundwater regulation within the district to prevent subsidence. As a result of Senate Bill 1336 in the 84th Legislature, the Edwards Aquifer Authority is no longer required to submit management plans to the TWDB. 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.
