USGS Groundwater Watch
USGS maintains a network of active wells to provide basic statistics about groundwater levels.
USGS in Your State
USGS Water Science Centers are located in each state.
Artificial recharge is the practice of increasing by artificial means
the amount of water that enters a groundwater reservoir (Todd, 1959).
This includes, for example, direction of water to the land surface through
canals, irrigation furrows or sprinkler systems, and injection of water
into the subsurface through wells.
