Bedrock Groundwater Levels for Selected Wells located in Western Pennington County

Bedrock aquifers are used extensively for water supplies in western Pennington County, and springs that discharge from these aquifers provide important baseflow for streams and reservoirs. A schematic diagram (fig. 1) shows the general hydrologic setting of bedrock aquifers in western Pennington County. The South Dakota Department of Environment and Natural Resources monitors water levels in a network of observation wells completed in these bedrock aquifers. The U.S. Geological Survey also operates several observation wells in these aquifers in cooperation with the city of Rapid City. Periodic measurements of water levels at these sites show the long-term trends in ground-water levels and how these aquifers respond to stresses such as drought. Water-level records for these observation wells may be observed graphically or downloaded by clicking on the map number showing the well location or the map number listed in the table of wells. Water levels are presented as feet below the land surface. Water levels for wells with pressure heads are presented as negative numbers that represent the feet above the land surface to which the water level would rise in an open stand pipe. This Web site was developed by the U.S. Geological Survey in cooperation with the South Dakota Department of Environment and Natural Resources and the West Dakota Water Development District.
