Since 2019, the Subsidence District has sponsored research conducted by Southern Methodist University (SMU) that utilizes a novel methodology to evaluate land-surface deformation (subsidence) in the region. 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. (4) "Groundwater" means water located beneath the earth's surface. Managing how groundwater resources are used is key to controlling subsidence. Contact information for the Harris-Galveston Subsidence District. Water supply evaluation and population projections are underway. Newsletters Working with surface water suppliers the HGSD controls subsidence by managing the use of groundwater resources in Harris and Galveston Counties. 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.

Star Groundwater Conservation District. 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. Overview of the Harris-Galveston Subsidence District planning process. 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. Pay Your Tax Bill Online Surface water rates dropped from $5.05 to $4.55, and the groundwater pumpage fee went from $4.60 to $4.10 per . USGS measures groundwater levels in over 700 wells in an 11-county area annually in the Houston-Galveston area in order to develop a regional depiction of groundwater levels. The RGUP was jointly supported by the Harris-Galveston Subsidence District, the Fort Bend Subsidence District, and the Lone Star Groundwater Conservation District. Land subsidence is the gradual lowering of land-surface elevation. Evaluation of Projected Population and Water Demands in Fort Bend County. Chicot-Evangeline (undifferentiated) and Jasper, which are composed of laterally discontinuous deposits Regular, precise, automated readings are taken of the elevation of the ground at locations throughout the county. Brazoria County Groundwater Conservation District, Lone Star Groundwater Conservation District. The districts vision is to manage the groundwater resources so that, in the near future, the amount of groundwater withdrawn from the Gulf Coast Aquifer is no more than the average annual effective recharge to the Gulf Coast Aquifer System. HGSD Financial Information including Budgets, Annual Audits, and Financial Reports. The new intake pump station will draw water from Lake Houston and, upon completion of the water treatment facility, will be able to provide 320 million gallons of treated water per day. For detailed information on the processing methodology, please refer to https://ascelibrary.org/doi/10.1061/%28ASCE%29SU.1943-5428.0000399. This process is crucial to prevent buildings from flooding. The District was created to provide for the regulation of groundwater withdrawal throughout Harris and Galveston counties for the purpose of preventing land subsidence, which leads to increased flooding. Regional water-level change maps were constructed by interpreting the compiled water-level altitude data The cumulative compaction in the Chicot-Evangeline undifferentiated aquifer is measured at 13 For more information, or to learn how to submit your report online, visit: https://lnkd.in/gSz5XemV. o35d8\,=R/.Y2xTE@;jj?4/gh?D$U2;MrpF&tMF6h-|l-:nSzC~ ER5knSP" zXyY/mY|{mm}x"S8K~"UILrD> Learn more: https://lnkd.in/gtXuURxS. each regional water-level altitude map. These efforts have identified and documented the susceptibility of land surface subsidence due to the production of groundwater in the Chicot and Evangeline aquifers.
