Environmental Aspects of Operation and Maintenance, Orwell Lake and Dam, Ottertail County, Minnesota.

摘要

Orwell Lake and Dam are located in Ottertail County, Minnesota, on the Ottertail River, and are operated primarily for the dual purpose of flood control and improvement of low-water flow. Flood runoff stored in the spring may be retained in the lake until needed during later months. The fluctuating water levels caused by operation adversely affect existing vegetation and fish and wildlife.
