Alters the flow of creeks and bayous which may increase the frequency and severity of flooding. 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. The Lone Star Groundwater Conservation District in 2012 purchased six Periodically Accessible Monitors (PAMs), which are specifically designed to detect subsidence. 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). 2001: Established by the Texas State Legislature.

As a result of Senate Bill 1336 in the 84th Legislature, the Edwards Aquifer Authority is no longer required to submit management plans to the TWDB. 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. historical year or as the difference in water-level altitude at each well for the water-level data Texas Water Development Board works best with JavaScript enabled. All Rights Reserved. With the last regulatory plan adopted in 2013, HGSD recently initiated a joint regulatory plan review in cooperation with the Fort Bend Subsidence District (FBSD) in January 2020. In cooperation with Damages roadways, bridges, building foundations, and other infrastructure. After collecting and evaluating groundwater-level data for quality control, data are incorporated into a Annual Groundwater Report, Cumulative Compaction of Subsurface Sediments, Regional Groundwater Update and more. This site is a publicly available, searchable, online database of water information.

In fact, the USGS serves as the hub for an annual multi-agency data collection effort that includes the Brazoria County GCD, Lone Star GCD, the City of Houston, and both subsidence districts. As the Houston Chronicle reported, Over the years, Texas lawmakers enacted bills to create subsidence or water conservation districts in counties that include Harris, Fort Bend, Montgomery and Galveston. Numerous subsurface faults have been documented beneath the Houston metropolitan area at depths of 3,200 to 13,000 feet. December 1, 2020. <> Harris-Galveston Subsidence Districts main mechanism of regulation is through its regulatory plan, with requirements laid out in the districts enabling legislation.

They have successfully slowed-down land subsidence, decreased flood risks, and overall maintained the viability of the area. Groundwater Conservation Districts | Texas Water Development Board The Authority has developed a groundwater reduction plan (GRP) and obtained Subsidence District approval of its GRP. Types of research sponsored by the District include: Each year the Board of Directors holds a public hearing for the purpose of taking testimony concerning the effects of groundwater withdrawals on the subsidence of land within the District during the preceding year. Trash 9 were here. These efforts have identified and documented the susceptibility of land surface subsidence due to the production of groundwater in the Chicot and Evangeline aquifers. 0 The water-level measurements in the dataset are built upon and stored in the National Water Information System: web interface, groundwater information, and field measurements website located here: http://dx.doi.org/10.5066/F7P55KJN.

Since the creation of the GMA, HGSD has provided information, research, and financial support to the GMA process. Harris-Galveston Subsidence District . 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. Data were compiled and multiple hydrologic parameters were utilized to improve the understanding of the brackish resources within the study area. endobj 5 0 obj The Board meetings are typically held at 5:30 PM on the first Wednesday of the month at The Lakehouse at Towne Lake, 10000 Towne Lake Parkway, Cypress, Texas 77433. }D?|=X'W|pqe'p]x/ In the Houston-Galveston region, land subsidence is caused by compaction of fine-grained aquifer sediments (silts and clays) Though subsidence rates are moderate in Fort Bend county, the continued heavy dependence of groundwater use may result in increased subsidence and associated impacts such as flooding and infrastructure damage. While some of the duties and goals are similar to those of groundwater conservation districts, Harris-Galveston Subsidence District (HGSD) is not governed by Chapter 36 of the Texas Water Code. %PDF-1.5 % Click here for more information about the Authority. Since it is not a GCD, HGSD participates in the activities of GMA 14 as an inter-local participant. Southeast Texas Groundwater Conservation District; Other Districts. After successfully implementing InSAR mapping in the Houston-Galveston region in 2019, this new project will harness the complimentary capabilities of the Subsidence Districts subsidence monitoring network and SAR imagery to develop these historical deformation maps. Now hiring a Deputy General Manager for Fort Bend Operations. 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. Water-level altitude contours, wells, and compaction data have been combined in an interactive map that allows users to view annual water-level altitudes from 1977 through the present, water-level changes over time, and historical time series of compaction data. These data were used to develop a groundwater flow model capable of simulating subsidence to inform the subsidence risk of brackish development of the Jasper aquifer. When we pump large amounts of water from the aquifers beneath us, we pull water out of the many layers of clay, which causes the clay to compact, lowering the elevation of the land above.
