[3] The embankment dam is of the rockfill type with a gated concrete spillway and outlet controls for regulating lake levels.

[4] Fall Creek Lake is one of 13 multi-purpose water projects managed by the United States Corps of Engineers in the Willamette Valley.

The reservoir, completed in 1966, functions mainly to control downstream flooding on the Willamette River but is also heavily used for recreation when the lake is full.

[3] In addition to a variety of campsites, amenities at the lake include picnic tables, boat ramps, swimming areas, toilets, and a fishing pier.

Forest Road 18 begins at the head of the lake and follows Fall Creek upstream for many miles to other campgrounds and hiking trails in the Cascade Range.
