The Fall Creek project is located on Fall Creek, a tributary of the Middle Fork Willamette River, about 22 miles southeast of Eugene in Lane County, Oregon. Fall Creek Lake has a moderate level of recreation facilities with two public day-use areas operated by Lane County and a campground operated by the Corps. The lake is heavily used for recreation, especially boating, fishing, swimming, and water-skiing.
Fall Creek has high capability for future expansion of camping and other recreation facilities.
The lake has a low drawdown priority for augmenting streamflows on the mainstem Willamette River in the summer, reflecting its relatively high priority for recreation. The Oregon Department of Fish and Wildlife uses Fall Creek reservoir as a rearing facility for spring chinook salmon. The project is operated to flush fingerlings from the reservoir in late fall. Use of this project is constrained by a lack of facilities, difficult access, and high degree of reservoir fluctuation. In 1996, Lane County constructed a boat launch facility at Signal Point which provides the only boat launching access throughout the year to the lake.
