Blue River Reservoir is an artificial impoundment, about 6 miles (10 km) long, of the Blue River in Lane County in the U.S. state of Oregon.[2][5] The reservoir is about 1 mile (1.6 km) north of Oregon Route 126 in the Willamette National Forest about 45 miles (72 km) east of Eugene.[1]

In 1968 the United States Army Corps of Engineers built Blue Lake Dam and Saddle Dam about 2 miles (3.2 km) from the mouth of the Blue River on the McKenzie River to create a reservoir for flood control and irrigation.[1][6] Despite frequent blooms of blue-green algae,[7][8] the lake is heavily used for recreation.[4] Trout are the principal fish, supplemented from local hatcheries.[2]


Blue River Reservoir is used for fishing, boating, swimming, and waterskiing.[1] The United States Forest Service manages Mona Campground, on the north side of the reservoir, and Lookout Campground, on the northeast side.[4] The Forest Service also manages two launching sites for motorized and non-motorized boats, one near Lookout Campground and the other near Saddle Dam on the south shore.[4] The reservoir supports populations of native coastal cutthroat trout and stocked rainbow trout.[2]
