Since 2019, the Subsidence District has sponsored research conducted by Southern Methodist University (SMU) that utilizes a novel methodology to evaluate land-surface deformation (subsidence) in the 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. Overview of Science and Research conducted by the Harris-Galveston Subsidence District, The strategic direction for science and research conducted at the Harris-Galveston Subsidence District. The District office will be closed on Monday, February 20, 2023, in observance of Presidents Day and will reopen during regular business hours on Tuesday, February 21, 2023. Click for .

Chicot-Evangeline aquifer in southeastern Harris County, and correspondingly, by 1979, as much as 10 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. For almost 50 years, they have been collecting, storing, and sharing data on groundwater abstraction and resulting surface lowering. The Harris-Galveston Subsidence District (HGSD) is a special purpose district created by the Texas Legislature in 1975. This study, spawned from their original research that showed subsidence in southern Montgomery County was caused by exploitation of the Jasper aquifer, will investigate the combined effects of climate changes on coastal subsidence to enhance understanding of the deformation process. Harris County MUD 501 purchases its water supply from Harris County Municipal Utility District 500, which purchases surface water from the Authority. Since it is not a GCD, HGSD participates in the activities of GMA 14 as an inter-local participant. Harris County MUD 501 is located within the boundaries of the Authority. From USGS well monitoring over decades they are able to show that once subsidence districts are created, groundwater levels rise significantly, thereby decreasing subsidence issues in their districts. levels rise, compacted sediments and the associated land-surface lowering would remain as-is. 1975: Established by Texas State Legislature. compaction data. 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. ArcGIS Online Map of Subsidence Rates in Fort Bend and Surrounding Counties, Texas, USA, 2020 Annual Groundwater Report Executive Summary, ArcGIS Online Map of Subsidence Rates in Fort Bend and surrounding Counties, Texas, USA. 1 of 3. 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 District enjoyed visiting the Houston Museum of Natural Science at Sugar Lands newest attraction, Ocean Bound: A Deep Dive Into the Science of How Water Flows. This interactive exhibit provides a look into how actions on land can impact water and even has an area designated for learning more about groundwater and subsidence. 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. 229 0 obj <>stream Alternative water sources, like treated surface water, prevents excessive groundwater pumping, thereby minimizing subsidence. GENERAL PROVISIONS Sec.A8801.001.AADEFINITIONS. While some of the duties and goals are similar to those of groundwater conservation districts, Harris-Galveston .

The U.S. Geological Survey, in cooperation with the Harris Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Brazoria County Groundwater Conservation District, and Lone Star Groundwater Conservation District, has produced this dataset of water-level changes and approximate water-level altitudes in the Chicot, Evangeline, and Jasper aquifers in the Houston-Galveston region, Texas. For keyboard navigation: First, use Arrow Keys to navigate up and down the districts. 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. Next, we traveled to the infamous Brownwood Subdivision, which was abandoned due to substantial subsidence in the 1980s. 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. Lone Star Groundwater Conservation District, Brazoria County Groundwater Conservation District, Fort Since its creation, subsidence rates have slowed greatly. When expanded it provides a list of search options that will switch the . Purpose: To manage groundwater withdrawal and enforce groundwater regulation throughout Harris and Galveston counties, in hopes of preventing the land subsidence that leads to increased flooding.

This is because in addition to sinking land elevations, subsidence contributes to flooding, inundation, or overflow of areas within the district, including rising waters resulting from storms or hurricanes. Extensometers and Subsidence. Purpose: To maintain the quality and availability of Brazoria Countys groundwater resources for current users and future generations. 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.
