Mud Lake Habitat Restoration

Project summary

The Minnesota Department of Natural Resources (DNR) proposes to improve hydrologic connectivity, reestablish deep-water habitat, reduce invasive species, and enhance coastal wetland habitat at Mud Lake within the St. Louis River Estuary. The proposed project would create a new channel, deep water habitat and marshes, remove a concrete structure and install a new 50-foot bridge. This is part of a collaborative effort under the Great Lakes Area of Concern Program to mitigate degradation and loss of habitat from historic activities in the St. Louis River. An environmental assessment worksheet (EAW) is required for the proposed project located in St. Louis County.
