Surface-water-altitude data, from streamgages, considered for the potentiometric-surface map, Mississippi River Valley alluvial aquifer, spring 2020

This dataset contains surface-water-altitude (SWA) data from streamgages that were used or considered (indicated by the field USE_2020) to create a potentiometric-surface map for the Mississippi River Valley alluvial aquifer (MRVA) for spring 2020. The SWA data was referenced to the North American Vertical Datum of 1988 (NAVD 88). The streamgages are measured continuously. The streamgage measurement that was used was from early April 2020 and is an estimate of the groundwater altitudes (GWAs) at the gage location. The resultant potentiometric-surface contours and raster represents the generalized central tendency for spring 2020, but it would not be useful for some purposes, such as for calibration of a groundwater-flow model for early April 2020 or for some local scale assessments.
