This project will create a culvert inventory for Cook County, Minnesota. The inventory will include the minimum data required in the Minnesota Department of Natural Resources ?Stream Crossing Basic Assessment Form? to be consistent with inventory work being done statewide and in other CWF grant projects such as the Lake County culvert inventory. While the watersheds in northeast Minnesota contain some of the least-polluted waters in the state, development and climate change pose an increased threat to aquatic resources if culverts are not installed, retrofitted, or replaced properly.
