Blue River

Blue River is a tributary of the McKenzie River in Linn and Lane counties in the U.S. state of Oregon. From its source at the confluence of Mann and Wolf creeks in the Cascade Range, it flows generally southwest to join the McKenzie near the community of Blue River. Saddle Dam and Blue River Dam block the river about 2 miles from its mouth to form Blue River Reservoir, a multipurpose impoundment built in 1968 by the United States Army Corps of Engineers.
The river's watershed lies almost entirely within the Willamette National Forest, dominated by western hemlock and Douglas-fir. Blue River was named for the striking blue color that apparently comes from its rocky bed.
