Wisconsin Groundwater-Level Monitoring Network Improvements, 2024-2026
This report documents work completed from 2024-2026 as part of a grant from the U.S. Geological Survey’s National Groundwater Monitoring Network (NGWMN) program. It provides an overview of the Wisconsin Groundwater-Level Monitoring Network (WGLMN) and …
Updated version of Depth to Silurian Bedrock in Eastern Wisconsin
Silurian-aged bedrock in eastern Wisconsin is shallow, fractured, and contains groundwater that is susceptible to surface water contamination. Revisions to Wisconsin state rules ATCP50 and NR151 to regulate manure spreading over this Silurian-aged bedrock create …
Bedrock Geology of Lafayette County, Wisconsin
Located primarily in the Driftless Area of southwest Wisconsin, Lafayette County is underlain by Paleozoic-aged bedrock, primarily siliciclastic and carbonate sedimentary units. These sedimentary rocks were mildly deformed during the Paleozoic, with fold amplitudes and …
Elevation Rasters of Geologic Contacts, Southwest Wisconsin
Elevation rasters (surfaces) were constructed for the base contacts of seven Paleozoic sedimentary lithostratigraphic groups in southwest Wisconsin. Meant to be used at a regional scale of 1:250,000, these surfaces were constructed to provide baseline …
Depth to Bedrock and Raster Elevation Surfaces of the Sinnipee and Ancell Groups, Jefferson County, Wisconsin
Located in southeast Wisconsin, Jefferson County is almost entirely blanketed by sediments that were delivered or shaped by the ice sheet that covered this area during the last ice age. Recent mapping interprets the distribution …
Geologic Map of the Weston and Menomonie South 7.5-Minute Quadrangles, Dunn County, Wisconsin
The 1:24,000-scale geologic map of the Weston and Menomonie South quadrangles is part of a larger project to map all of Dunn County. Prior mapping work in the area was regional in extent (1:250,000-scale), so this …
Hydrogeologic Atlas of Burnett County, Wisconsin
This hydrogeologic atlas offers a comprehensive interpretation and analysis of groundwater resources across Burnett County, Wisconsin. It encompasses assessments of the water-table elevation and groundwater flow directions, depth to the water table, depth to bedrock, …
Wisconsin Bedrock Topography, 100-Meter Resolution
This is the first statewide depth to bedrock (bedrock topography) compilation since the statewide map Depth to Bedrock in Wisconsin(link) by Trotta and Cotter in 1973. WGNHS GIS Specialist Matthew Rehwald used modern GIS …
Quaternary Geology of Vernon, Crawford, and Richland counties, Wisconsin
The topography of the Driftless Area, which was never glaciated during the Quaternary Period, is dominated by fluvial incision into flat-lying Paleozoic bedrock, resulting in deep, dendritic valleys. Local relief reaches 115 meters. Sediment coring …
