Cottage Grove Lake is a reservoir located in Lane County, Oregon. The lake was created in 1942 by the construction of Cottage Grove Dam on the Coast Fork Willamette River. The dam's primary purpose is to provide flood control and hydroelectric power to the region. The lake's hydrology is influenced by its location in the Coast Range, which receives significant amounts of precipitation. The primary surface flow provider is the Coast Fork Willamette River, while snowpack also contributes to the lake's water supply. The lake is used for a variety of recreational activities, including boating, fishing, and swimming, and it also provides irrigation water for nearby agricultural operations. The area surrounding the lake is home to a variety of wildlife, including bald eagles and otters.
