Occasionally, the district undertakes a review of the regulatory plan, working with other entities to assess future water needs and ensure that the plan will be successful in ceasing subsidence. However, there is another cause of subsidence in our area which causes the activation of surface faults (which can damage roads, houses, and buildings), loss of wetlands and . City of Houston, TX: Boards - Granicus Trash Alternative water sources, like treated surface water, prevents excessive groundwater pumping, thereby minimizing subsidence.

Up to 2020, regional water-level altitude maps were created by manually interpolating contours of The district proactively works with its groundwater users to address issues such as how to most efficiently use groundwater, control and prevent waste, control and prevent subsidence, and address drought conditions. 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. 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. Data provided by the USGS. Surface water rates dropped from $5.05 to $4.55, and the groundwater pumpage fee went from $4.60 to $4.10 per . Extensometers and Subsidence - San Jacinto River Authority Regular, precise, automated readings are taken of the elevation of the ground at locations throughout the county. 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). City 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. On the first stop, we visited the Texas City Rainwater Pump Station, where Texas Citys Emergency Management team takes runoff rainwater from ditches in the area and pumps it into Moses Lake. Explore Groundwater-Level and Compaction Data in the Chicot, Evangeline and Jasper Aquifers. After collecting and evaluating groundwater-level data for quality control, data are incorporated into a Land subsidence is the gradual lowering of land-surface elevation. 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. Most compaction that occurs as a result of groundwater withdrawals is irreversible; even if groundwater Harris-Galveston Subsidence District and West Harris County Regional Working with surface water suppliers the HGSD controls subsidence by managing the use of groundwater resources in Harris and Galveston Counties. HGSD works closely with State and Federal agencies to foster collaboration and improve governmental efficiency. The goal was to keep the region elevated by developing ways to reduce groundwater consumption.. It has since been turned into the Baytown Nature Center. 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. You can also view water levels by visiting the Lone Star Static Well Level Monitoring Network Map. Groundwater-level and compaction data are available as part of USGS data products. %PDF-1.5 % Subsidence is known to have occurred in the southern part of Montgomery County based on monitoring and long-term surveying of land surface.

Zilkoski, Lucy W. Hall, Gilbert J. Mitchell, Vasanthi Kammula, Ajit Singh, William M. Chrismer, and Ronald J. 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. Since the mid 1970's, the USGS and the Harris-Galveston Subsidence District have conducted scientific investigations and subsidence monitoring for over 40 years. Reduces the ability to store water in an aquifer. USGS measures groundwater levels in over 700 wells in an 11-county area annually in the Houston-Galveston area in order to develop a regional depiction of groundwater levels. The accuracy of the referenced well land-surface altitude data has improved through time and the most the U.S. Geological Survey Texas Water Science Center Gulf Coast Program collects, processes, and The Harris-Galveston Subsidence District, created in 1975, was the first of these districts.

Since 1836, groundwater withdrawals have caused about 3,200 square miles of the Houston-Galveston area to subside (or sink) more than a foot, with some areas subsiding as much as 12 to 13 feet. Brazoria County Groundwater Conservation District, Lone Star Groundwater Conservation District. HGSD is governed by a board composed of 19 directors appointed by mayors and entities withing HGSD boundaries. 1999: Regulatory areas converted into 3 primary areas. The Authoritys GRP sets forth the Authoritys plan to comply with the Subsidence District regulations, construct surface water facilities, and convert users from groundwater to alternate source water (e.g., surface water). The RGUP originally started in 2010 as the Harris-Galveston Subsidence District (HGSD) 1999 Regulatory Plan Update, but due to its benefits to other regional groundwater regulatory agencies, the Fort Bend Subsidence District (FBSD) and the Lone Star Groundwater Conservation District (LSGCD) joined the collaborative effort in 2010.The primary benefit of collaboration between these three entities is that each of them could use the RGUP to vet their existing regulatory plans using updated population/water demand data and groundwater modeling capability, and in the case of HGSD and FBSD, investigate the physical effects of changing their existing regulatory plans to accommodate the practical realities facing their stakeholders while successfully completing the Districts mission objectives.
