After collecting and evaluating groundwater-level data for quality control, data are incorporated into a 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. Water demands were projected . The Harris-Galveston Subsidence District is a special purpose district created by the Texas Legislature in 1975 to regulate groundwater withdrawal throughout Harris and Galveston counties in order to prevent land subsidence. By 1977, an extensive groundwater well-monitoring network had been established and the USGS had collected water-level data that were used to create the first published water-level altitude maps of the Chicot and Evangeline aquifers in the Houston-Galveston region. Since its creation, subsidence rates have slowed greatly. 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. Lone Star GCD is working with the Subsidence District to make the newer stations available online.

Trash Areas of the nature center show reminiscences of the neighborhood and serve as an important reminder of what subsidence can do. In addition HGSD provides water conservation, education, and outreach programs to underscore the importance of water conservation in the community. These efforts have identified and documented the susceptibility of land surface subsidence due to the production of groundwater in the Chicot and Evangeline aquifers. All Rights Reserved. 1999: Regulatory areas converted into 3 primary areas. 2001: Established by the Texas State Legislature.
