While some of the duties and goals are similar to those of groundwater conservation districts, Harris-Galveston . The nearby hydrograph shows that when a subsidence district was created around 1976 (red line), groundwater levels in the Chicot Aquifer rose substantially. Water supply evaluation and population projections are underway. Datasets of water-level changes and altitudes in the Chicot, Evangeline, and Jasper aquifers. available to store water resulting in the lowering (sinking or settling) of the land-surface.

Working with surface water suppliers the HGSD controls subsidence by managing the use of groundwater resources in Harris and Galveston Counties. The districts vision is to manage the groundwater resources so that, in the near future, the amount of groundwater withdrawn from the Gulf Coast Aquifer is no more than the average annual effective recharge to the Gulf Coast Aquifer System. 8X>F|9L'a{:Vh41tX p`;WDWjxWu{F$I8x}C/rQA6VT\=#_ 68q RJGE0KWp|nxDrQnvc#|Wl Zi4dg9H#qU@xz?$' x[k gH x$C8c:Bes9$_(Rs]j~4KNSB@-. Annual Pumpage Reports are due by January 31, 2023. City The Subsidence District has adopted regulations requiring reduction of groundwater withdrawals through conversion to alternate source water (e.g., surface water) in certain areas within the . their jurisdiction. 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. Harris-Galveston Subsidence District reposted this, Mitigation of human-induced land subsidence starts with the regulation of resource extractions. water levels in the aquifer were declining with associated depressuring, dewatering, and compaction Land subsidence is the gradual lowering of land-surface elevation. 4Rw,De@5hfbHY`b`H=n We I$@g|0 <> established the Fort Bend Subsidence District and two groundwater conservation districts: Lone Star The District Science and Research Plan represents the strategic direction for science and research conducted or supported by the Fort Bend Subsidence District (FBSD) and, as such, is an essential component of the Districts regulatory planning process.

This process is crucial to prevent buildings from flooding. 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. Lone Star Groundwater Conservation District, Brazoria County Groundwater Conservation District, Fort Harris County MUD 501 is located within the boundaries of the Authority. Since it is not a GCD, HGSD participates in the activities of GMA 14 as an inter-local participant.
