The 112-acre Lake Mattawa boasts very clear water - you can see 15 feet down - and the reputation of producing trophy trout. The trout's success here is probably due to the numerous springs that feed the lake and the high number of the smelt they forage on. Other fish found here include smallmouth bass, pumpkinseed, bluegill, yellow perch, golden shiner, white sucker, and brown bullhead. The state stocks the waters each spring with rainbow and brown trout.
Two paved ramps on Lake Mattawa Rd. provide public boat access; motorboats are restricted to 10 hp or less. Swimmers enjoy a small, unsupervised beach. The shoreline of the lake is 75 percent developed, but set within a forested "neighborhood," the lake still offers a lovely spot for summer recreation. Anglers also head here in winter, to try their hand at ice fishing.
