Potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2020, raster format, in meters

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-09-13T00:00:00Z
This dataset is the raster, in meters, of the potentiometric-surface map, spring 2020, Mississippi River Valley alluvial aquifer (MRVA). The raster cell size is 1,000 meters; the raster was referenced to the North American Vertical Datum of 1988 (NAVD 88). The raster, in feet, was interpolated using most of the available groundwater-altitude (GWA) data from wells, surface-water-altitude (SWA) data from streamgages, and the potentiometric contours. Then the raster altitude data was converted to meters.
