Depth-to-Bedrock Mapping in Wisconsin
Depth-to-bedrock maps show the thickness of unconsolidated materials overlying bedrock. These maps provide a key link between the underlying geology, groundwater flow, and land use and are important in guiding activities such as permitting, bridge construction, and the land application of waste products in sensitive areas. Given their role in guiding... -
Depth-to-Bedrock Map of Dodge County, Wisconsin
This map shows thicknesses of deposits of unconsolidated materials above the bedrock. Across the county, depth to bedrock ranges from 0 feet, where bedrock is exposed, to over 250 feet within bedrock valleys. Areas with bedrock depths shallower than 20 feet are of particular importance for land-use planning and to the construction stone industry. Such... -
Bedrock Geology of Dodge County, Wisconsin
Dodge County lies in southeast Wisconsin, an area almost entirely covered by glacial deposits. This map interprets the distribution of the buried bedrock units across the county. Geologist Esther Stewart’s refinement of the bedrock elevation contours may help land-use planners identify areas most susceptible to groundwater contamination from applications...-

2017 Year in Review
In 2017, Survey staff worked in 69 Wisconsin counties. We mapped geology, inventoried springs, and created groundwater models. We provide natural resource managers – land and water conservationists, county boards, and water utilities – with the information they need to protect and share their resources. This publication provides a summary of some of the... -
