This child item contains geology and hydrogeology data used in the hydrogeologic characterization of the Lake Superior watershed and a shapefile of water budget zones for reporting water budget terms for Lake Superior. The geology data include shapefiles of bedrock units from the USGS Geologic map database (Horton, 2017) and surficial geology units from Soller and others (2012). A compilation of hydrogeologic properties (hydraulic conductivity and transmissivity) from a variety of studies in and around the Lake Superior basin and from a field study conducted in 2021 is included in a data table and the values are applied to the bedrock and surficial unit shapefiles. We also include here a zipped grid of simulated groundwater discharge to surface water (rivers and streams) extracted from the Zell and Sanford (2020) MODFLOW6 model of the shallow groundwater in the United States. The sources of data used in the compilation of properties also are included.

This data release contains a data compilation and analysis of the hydrogeology in the U.S. portion of the Lake Superior watershed, for the purpose of providing background data for future study and modeling of groundwater and contaminant movement in the watershed. The data support an analysis of groundwater contributions to the water budget of Lake Superior and provide hydrogeologic context for future modeling and sampling of groundwater in the region. The data release contains three child items: Baseflow analysis for tributaries to Lake Superior from 1946 to 2020; Geohydrology data for groundwater analysis in the Lake Superior Watershed; and Groundwater wells from Minnesota, Wisconsin, and Michigan state databases and the U.S. Geological (USGS) National Water Information System (NWIS) database with static water level data within 10km of the Lake Superior watershed.

This Open Geospatial Consortium (OGC) GeoPackage (.gpkg) contains water-well point features and associated tables for the state of Minnesota that have been reformatted based on a USGS profile of the OGC GroundWaterML2 (GWML2) standard (https://docs.ogc.org/is/19-013/19-013.html). The water-well records provided in this data set have not received additional processing or interpretation by the USGS beyond the GWML2 standardization. The National Water-Well Database (NWWDB) is a compilation of water-well records from state-managed databases that have been standardized to a common format for consistency across state and administrative boundaries. Water-well completion reports that are submitted to permitting state agencies by licensed drillers constitute a large source of hydrogeologic information, including the locations and distribution of water wells, construction materials and completion depths, lithologic logs, groundwater levels, and the results of pumping or aquifer tests.

This vector geospatial dataset contains bounding polygons that visualize the domain of archived groundwater flow models published by the Upper Midwest Water Science Center and attributes pertaining to the associated publication (citation, year of publication, authors, report ID, publication URL), model construction details, and a URL for publicly available model archives when available or a directory pathway for internal model archives. The index currently depicts 115 groundwater model domains across Michigan, Minnesota, and Wisconsin from publications dating back to 1985. Separately published groundwater transport models are not included in this dataset.

Additionally, the water-well records have been quality-assured to remove or nullify parts of water-well records found to be erroneous or logically inconsistent, harmonized via the assignment of common data codes in the lithologic log, and supplemented with estimates of transmissivity from the analysis of specific-capacity data.

The U.S. Geological Survey (USGS) created geospatial datasets of potential culvert locations along with flowlines connected to southwestern Lake Erie as part of the Western Lake Erie Restoration Assessment (WLERA). The Degree Flowlines and Culverts datasets represent the flowline network and culverts in the WLERA study area. Both datasets will be served in the Great Lakes Wetlands Restoration Area mapping application [https://glcwra.wim.usgs.gov/]. The map-based user interface can be used by stakeholders to find potential areas for successful wetlands restoration. Each flowline was assigned a connectivity score describing its level of connectedness to Lake Erie. Low numbers represent fewer disconnections, such as culverts or road crossings, between the reach and the water body requiring no flow network modification to restore the area. For more information, see the full data release documentation and the GLCWRA webpage: https://glcwra.wim.usgs.gov/.
