Coho Campground, managed by the
Olympic National Forest, is upstream from the dam. The campground has running water, restrooms, has a day use area, with cooking pits. There are 46 sites in the campground with fire pits and picnic tables, room for tents, trailers, motor homes, and these sites are charged a fee. There is also a boat ramp. There is a camp host there almost every day. Tacoma Power operates a day use picnic and swimming area along the shore of the reservoir closest to the dam. Approximately of the Upper Wynoochee Valley Road (Forest Service Development Rd 22) has been paved including the access road for the Wynoochee dam and recreational areas, this includes the Coho camp ground. This allows much faster traveling to and from the dam from Hwy 12 and the city of Montesano. The Donkey Creek Road (also Forest Service Development Rd 22) from Hwy 101 to the dam is currently paved from Highway 101 into the National Forest approximately , and gravel the remainder of the way to the junction of FS2294. ==References==
