Modification Project, Big Stone Lake-Whetstone River, Minnesota and South Dakota, Draft Supplement to Environmental Impact Statement.
Abstract
The Big Stone Lake-Whetstone River Modification Project was authorized by the Flood Control Act approved 27 October 1965. The Final Environmental Impact Statement was filed with the President's Council on Environmental Quality on 18 December 1971. Construction has been completed for all project features except for the upstream works on the Minnesota River and the areas of rechannelization and bank stabilization on the lower 4 miles of the Whetstone River. This supplement has been prepared to address a significant alignment change for the proposed diversion channel into the project U.S. Highway 75 Reservoir in the Big Stone National Wildlife Refuge and to fulfill requirements which were established subsequent to preparation of the final EIS: (1) the Endangered Species Act of 1973, as amended, and (2) Section 404(b) of the Clean Water Act of 1977 and applicable Corps of Engineers regulations and guidance. The supplement itself consists of three parts: (1) an evaluation of the significant environmental impacts which would be expected to result from construction of the diversion channel along the new alignment; (2) a Section 404(b)(1) evaluation of all remaining all activities associated with work on the Whetstone and Minnesota Rivers; and (3) a biological assessment which addresses the impacts of remaining work on all currently listed threatened and endangered species.
