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. The data is temporarily stored in an on-site monitor and periodically uploaded to computers at the Harris Galveston Subsidence District. The Subsidence District has adopted regulations requiring reduction of groundwater withdrawals through conversion to alternate source water (e.g., surface water) in certain areas within the Subsidence Districts jurisdiction, including the land within Harris County MUD 501. Subsidence can be an important issue in certain areas such as the Gulf Coast region. Click here for more information about the Authority.
