Flood Control, Roseau River, Roseau and Kittson Counties, Minnesota. Final Environmental Impact Statement. Supplement.

摘要

This document supplements the Final Environmental Impact Statement (FEIS) for Flood Control, Roseau River, Roseau, Minnesota. Coordination with Federal and State agencies and public interest groups continued after completion of the FEIS. Two principal concerns arose during that coordination: the adverse impacts on fish and wildlife habitat and the potential for project-induced drainage. Project alternatives, including one not identified in the FEIS, were reevaluated and are discussed in this supplement. Through active coordination with the U.S. Fish and Wildlife Service and the Minnesota Department of Natural Resources, measures to reduce impacts to the fish and wildlife of the watershed were identified evaluated, and included in the project design. Vegetation would be planted specifically to provide wildlife habitat on land belonging to the State of Minnesota, including the temporary right-of-way. To address the concern of project-induced drainage, the outlets of ditches entering the river would be fixed in both elevation and capacity at the hydraulic control point. Fixing the ditch outlets would prevent anyone from altering the gradient of a ditch to extend it further from the river.
