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. 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. It has since been turned into the Baytown Nature Center. <>stream City destroyed or were not measured during the individual publication study period. <> 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. For almost 50 years, they have been collecting, storing, and sharing data on groundwater abstraction and resulting surface lowering. water-level altitude and regional water-level change contour map can be found in the individual year 9 were here. extensometer stations in the 11-county area. Water-level altitude, well, and compaction data have been combined in an interactive map that allows Providing analysis of accurate and up to date predictions on water usage; the enforcement of real disincentives to those who rely too heavily on groundwater; and an unwavering commitment to practicing and promoting water conservation. HARRIS-GALVESTON SUBSIDENCE DISTRICT SUBCHAPTER A. Up to 2020, regional water-level altitude maps were created by manually interpolating contours of 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. The districts vision is to manage the groundwater resources so that, in the near future, the amount of groundwater withdrawn from the Gulf Coast Aquifer is no more than the average annual effective recharge to the Gulf Coast Aquifer System.
