Cougar Reservoir, reservoir in Oregon
Cougar Reservoir is a large body of water in Oregon's Cascade Mountains, covering about 1,280 acres and surrounded by forest. The lake reaches depths of up to 425 feet in some areas, with three main campgrounds located near its shoreline for visitor access and recreation.
The reservoir was created in 1963 when the U.S. Army Corps of Engineers built Cougar Dam on the South Fork McKenzie River to control flooding and generate electricity. This construction transformed the landscape and established a new location for both recreation and water management in the region.
The reservoir is located within Willamette National Forest and serves as a gathering place for both locals and visitors seeking outdoor leisure. The calm water and forested setting encourage simple activities like picnicking, walking along the shoreline, and observing the natural surroundings.
The area is accessible via Highway 126 from Blue River and offers three main campgrounds with tent and RV sites. Visitors should note that restrooms and drinking water are not available at the reservoir itself, so it is important to bring supplies needed for a full day outdoors.
Near the reservoir sits Terwilliger Hot Springs, a natural hot spring located along Rider Creek just west of the lake, accessible by a short hike. Many visitors add this warm water spot to their visit as an unexpected bonus, especially during cooler months.
