This data release provides the data that support the findings in "Characterizing groundwater and surface-water interaction using hydrograph-separation techniques and groundwater-level data throughout the Mississippi Delta" by Killian and others (2019). There are two child items below: (1) Estimated baseflow includes the baseflow_est data and metadata that contain daily mean streamflow data provided by the U.S. Geological Survey (USGS) and the U.S. Army Corps of Engineers (USACE), as well as estimated daily mean streamflow records for any missing data and the hydrograph-separation and trends analyses results for the five selected sites output by the USGS Groundwater Toolbox (; and (2) Generalized [...]
