U.S. Geological Survey real-time monitoring station

A U.S. Geological Survey real-time monitoring station (station 440326103180702) located near Jackson and Cleghorn Springs on the west edge of Rapid City near Rapid Creek monitors water levels in the Madison aquifer. The well is 640 feet deep and is under pressure. A pressure transducer records water levels that are then transmitted by satellite and displayed on NWISWeb under real-time data, ground water. Continuous water-level records for the Madison aquifer at this site are especially important because of the many beneficial uses of water from Jackson and Cleghorn Springs, which discharge primarily from the Madison aquifer.
