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. endstream endobj 190 0 obj <>stream This study provides a basis for future research on subsidence in the Districts area and can inform water managers and planners in the Houston area on the availability of brackish groundwater resources. GALVESTON COUNTY CHAMBERS COUNTY LIBERTY COUNTY WALLER COUNTY 45 249 59 U.S. Department of the Interior U.S. Geological Survey Pamphlet to accompany Scientific Investigations Map 3365 Prepared in cooperation with the Harris-Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District . Overview of the Harris-Galveston Subsidence District planning process. Chicot-Evangeline (undifferentiated) and Jasper, which are composed of laterally discontinuous deposits 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. 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. This district was created because area residents and local governments were becoming increasingly alarmed by subsidences continued impact on the regions economic growth and quality of life. 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. If you are a leader with a passion for executing projects that improve our local communities, check out this opportunity! water below land surface) from the referenced well land-surface altitude. A report by: David B. Zilkoski, Lucy W. Hall, Gilbert J. Mitchell, Vasanthi Kammula, Ajit Singh, William M. Chrismer, and Ronald J. (4) "Groundwater" means water located beneath the earth's surface. Alters the flow of creeks and bayous which may increase the frequency and severity of flooding. Lone Star GCD is working with the Subsidence District to make the newer stations available online. 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.. 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. 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. regional water-level change maps. During todays Board Meeting, Rosa Alvarez, Susan Baird, Sarah Benavides, Steve Gillett, Katherine Mears, and Don Johnson were reappointed and took their Oath of Office. GULF-2023 Model Development & USGS Partnership. 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.
