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. This is accomplished through the careful regulation of groundwater withdrawals, working in collaboration with surface water suppliers. A focus of these scenarios will be on the variables that minimize subsidence in the future while accounting for the availability of alternative water supplies. The District uses exceptional scientific research to ensure the best available technology and approaches are considered with respect to water management and subsidence monitoring. their jurisdiction. feet of subsidence had occurred in the Houston-Galveston region.
