Interactive map of groundwater levels and subsidence in the Houston-Galveston area

The U.S. Geological Survey provides an interactive map that allows users to view changes in groundwater levels and associated land subsidence from 1977 to 2016 in the Houston-Galveston area.

The map uses annual data from over 700 wells in 11 counties, and shows changes in water levels in three major aquifers in the region: the Chicot, Evangeline, and Jasper aquifers.

Interactive map of water wells in South Dakota

The South Dakota Department of Environment and Natural Resources provides an interactive map of water wells in the state based on water well completion reports. Users can search for wells by place, ownership, well type, driller, and date of completion.

By clicking on an individual well, you can access well data and the completion report. All data and reports can be downloaded for further use. The interactive map also provides a searchable database of drillers and pump installers in the state.
