Additionally, the US Geological Survey (USGS) has begun work on the GULF-2023 model, with an anticipated completion date in the fall of 2021. water-level altitude data at observation wells in the Houston-Galveston Region. 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 button displays the currently selected search type. The District was created to provide for the regulation of groundwater withdrawal. In cooperation with HGSD lies within the boundaries of Groundwater Management Area 14 (GMA 14). https://lnkd.in/gZKAs__D. In addition to regulation, the district also conducts research to enhance its understanding of the Upper Gulf Coast aquifer to better manage subsidence. 218 0 obj <>/Filter/FlateDecode/ID[<47E07B46D706934486CB2062ED92DA88><05048E564C3EFD429B1933026D915C3D>]/Index[186 44]/Info 185 0 R/Length 144/Prev 850166/Root 187 0 R/Size 230/Type/XRef/W[1 3 1]>>stream )|#.`/D;WcM0z,B] mXU+^yZ!9K254cC.(WjoFgpK1EpvgoV "H7 OKQ:kHLa`Z=Hmm'rh`:Qfb5.!H{ 6+sBQ xX6~R-N\dq?%cBa:77#KZO=~`[h[VPC-!q8cVBv1j0Bh}vcu-7~6G~@ ucM,-s-9i4_g8jO00J\iOSktweZ.wfbuy9;Q^WGeQUab=~2_GK Z/fox$mTLMNX/ke5'a(7X=NCi>26*'$!3 Copyright 2023 The Texas Alliance of Groundwater Districts.

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. HGSD conducts regulatory planning on a regular basis to confirm that adopted regulations have reduced subsidence rates. Harris-Galveston Subsidence District (HGSD) in Texas was recognized as a WaterSense Partner of the Year for the first time for helping residents and businesses save water outdoors. Subsidence is known to have occurred in the southern part of Montgomery County based on monitoring and long-term surveying of land surface. 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. 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 . Water-level altitude, well, and compaction data have been combined in an interactive map that allows In Houston, land subsidence is caused by the withdrawal of groundwater. historical year or as the difference in water-level altitude at each well for the water-level data This report, prepared by the U.S. Geological Survey in cooperation with the Harris-Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District, is one in an annual series of reports depicting water-level altitudes and water . sOsOg_oW uMfM "F6H1#]Q]9gv3] m ]:U3*~=lrz&/tU=j4VRi/Y?Qk#mLiQ&~9zOo,6L#?~"|HJ@uF~[L iaG,):LUCB$\zB+B=zT& HGSD is divided into three regulatory areas stretching from High Island and Galveston upwards to Hempstead, TX.

Ground-Water Withdrawals and Land-Surface Subsidence in the Houston-Galveston Region, Texas, 1906-80: R-286: 4/1/1984: TWDB numbered report: This effort has published aquifer levels and subsidence data since 1975 and is a great example of what can be accomplished through sustained collaboration between, city, county, regional, and federal partners. Brazoria County Groundwater Conservation District . The Harris-Galveston Subsidence District maintains GPS monitoring stations in Harris, Galveston, Fort Bend and surrounding counties. Creation year: 2001 (77th Texas Legislature). Purpose: To manage groundwater withdrawal and enforce groundwater regulation within the district to prevent subsidence. Land subsidence is sinking of the land surface, caused by compressing the many layers of clay beneath the surface. By 1977, the withdrawals had resulted in water-level altitude declines of 350 feet below datum in the larger image. 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. Further information detailing the data processing and map creation for each published regional 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.). HGSD has the goal of reducing the area to 20% reliance on groundwater by 2035 and managing water to promote .
