Harmon Lake Recreation Area features a 145-acre reservoir located on Otter Creek. The reservoir measures 38 feet at its deepest point. Rock fishing piers and a boat ramp and dock provide access opportunities for those to enjoy the lake. Two sandy beaches are located along the shore of the lake. Harmon Lake is a no wake waterbody, meaning boats must travel at a slow idle speed. Personal watercrafts are not allowed on the lake. The lake is stocked with rainbow trout and cutthroat trout fingerlings.
The multiuse trail features 13.1 miles of terrain for biking, hiking or birding. The trail is designed as a sustainable single track, unpaved trail allowing walkers, hikers, birders or bikers reach several areas throughout the recreation area.
Camping is also available at the lake. There are 33 individual spots and two 5 camper group pads, all with electricity. Individual sites are available on a first come first served basis, unless you rent a shelter. The group pads can be reserved.

Future plans include constructing shelters, a multi-use building to accommodate large group gatherings, volleyball courts, playgrounds, public restrooms with showers and horseback riding facilities.
