    • Potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2018, raster format, in meters

    Metadata Updated: November 27, 2025

    This dataset is the raster, in meters, of the potentiometric-surface map, spring 2018, Mississippi River Valley alluvial (MRVA) aquifer. 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 data from wells, surface-water-altitude data from streamgages, and the potentiometric contours. Then the raster altitude data was converted to meters.
