Datasets of depth to water, spring 2016, 2018, and 2020, and spring-to-spring water-level change 2016-18, 2018-20, and 2016-20, Mississippi River Valley alluvial aquifer

This data release consists of 4 data sets--rasters of generalized depth to water in the Mississippi River Valley alluvial aquifer (MRVA) in spring 2016, 2018, and 2020 and a point file of the wells with water-level measurements used to create the depth to water rasters and, for each well with applicable data, the values of water-level change from spring 2016 to spring 2018, spring 2018 to spring 2020, and spring 2016 to spring 2020. The MRVA underlies parts of seven states, including Arkansas, Illinois, Kentucky, Louisiana, Missouri, Mississippi, and Tennessee These data sets were created to characterize the depth to water in the MRVA and the value of water-level change at each well with the applicable data. These data sets can be used to facilitate understanding of the MRVA and to assist in further analysis of other MRVA data, as for example, water quality results.
