Datasets used to map the potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2020 A potentiometric-surface map for spring 2020 was created for the Mississippi River Valley alluvial aquifer (MRVA), which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. The location and water-level altitude in feet for these wells and streamgages in spring 2020 are provided in this data release. The interpreted contours and raster of the potentiometric surface are also provided in this data release and in the associated report titled "Potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2020" and available at https://doi.org/10.3133/sim3478/. Tags: USGS Science Data Catalog (SDC) Datasets used to map the potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2018 A potentiometric-surface map for spring 2018 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. Most of the wells were measured annually or one time, after installation, but some wells were measured more than one time in a year and a small number of wells were measured continually. Streamgages were typically operated continuously. The potentiometric-surface map for 2018 was created as part of the U.S. Geological Survey (USGS) Water Availability and Use Science Program to support investigations that characterize...
