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 the need for a depth-to-bedrock map of eastern WI. The Wisconsin Geological and Natural...-

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... -
