EXECUTIVE SUMMARY: The Fort Bend Subsidence District (FBSD) revised its District Regulatory Plan (DRP) in 2013 based on population and water demand projections, which were developed as part of a Regional Groundwater Update Project (RGUP) completed in 2013. In order to evaluate the performance of the projection methodology which informed the 2013 DRP, the short-term projections from the RGUP have been evaluated against recent estimates of population and water demand from multiple sources at various geographic scales. Legislature authorized the establishment of the Harris-Galveston Subsidence District to regulate and HGSD is divided into three regulatory areas stretching from High Island and Galveston upwards to Hempstead, TX. The districts vision is to manage the groundwater resources so that, in the near future, the amount of groundwater withdrawn from the Gulf Coast Aquifer is no more than the average annual effective recharge to the Gulf Coast Aquifer System. #Hiring The U.S. Geological Survey prepared this dataset in cooperation with the HarrisGalveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District. https://lnkd.in/gkwTtcAZ.
