Surface water rates dropped from $5.05 to $4.55, and the groundwater pumpage fee went from $4.60 to $4.10 per . 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.

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. Chicot-Evangeline (undifferentiated) and Jasper, which are composed of laterally discontinuous deposits 5 0 obj This report documents the impact of groundwater use on aquifer water levels and subsidence within the District and was prepared in accordance with an Inter-local Agreement between the District and the Harris-Galveston Subsidence District (HGSD). 1985: Divided into 8 regulatory areas by amount of groundwater reduction needed. The Harris-Galveston Subsidence District, in cooperation with the Fort Bend Subsidence District, the Brazoria County Groundwater Conservation District, the Lone Star Groundwater Conservation District, the University of Houston, and the Brazosport Water Authority maintains a subsidence monitoring network that is constantly evolving and requires consistent investment.

Register a well, permit applications, renewals, and amendments. In the event of an emergency, please dial 9-1-1. 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. Conventional Measurement Method, Borehole Extensometers, GPS, and Measuring Subsidence in the Future.

Water-level change in the Gulf Coast Aquifer, 1977 to 2018. Managing how groundwater resources are used is key to controlling subsidence. Additionally, the US Geological Survey (USGS) has begun work on the GULF-2023 model, with an anticipated completion date in the fall of 2021. hmo0?:;T!AR~p!A+~g`e]rw>F "1T"@0D$L$!A!JyXUJsm\Ouu~o:p11G5r[U=w/ QdQUq] .

She joins Harris County from the Harris-Galveston Subsidence District, where she has served as Deputy General Manager for the past 3 years and oversaw the District's Regulatory Planning, Scientific Research, and Water Conservation Programs. Fort Working with surface water suppliers the HGSD controls subsidence by managing the use of groundwater resources in Harris and Galveston Counties. Fort Bend Subsidence District The Harris-Galveston Subsidence District maintains GPS monitoring stations in Harris, Galveston, Fort Bend and surrounding counties. 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. <>stream Bandera County River Authority & Groundwater District Featured District, Develop population and demand projections for 10 counties through 2100, Conduct alternative water supply assessment, Develop the Gulf Coast Land Subsidence and Groundwater Flow (GULF)-2023 model with US Geological Survey and Texas Water Development Board, Update the analytical subsidence models previously used by the HGSD and FBSD, Groundwater regulation (or lack thereof) in adjacent counties. extensometer stations in the 11-county area. Harris County MUD 501 is within the boundaries of the Harris Galveston Subsidence District (the Subsidence District) which regulates groundwater withdrawal. Regional water-level change maps were constructed by interpreting the compiled water-level altitude data 9 were here. 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 . The Houston area's two subsidence districts the Harris-Galveston Subsidence District, HGSD, and the Fort Bend Subsidence District have worked to monitor subsidence and mitigate it through a variety of water management efforts. In cooperation with 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. In addition, they involve local communities by education and outreach programs to underscore the importance of water conservation, such as publishing an interactive viewer with GPS land subsidence monitoring stations (shown below).
