Fernhill Wetlands

Fernhill is part of more than 700 acres in Forest Grove owned by Clean Water Services for water resources management. Fernhill utilizes natural treatment systems or wetlands to improve water quality by removing nutrients, cooling, and naturalizing the water after initial treatment at the Forest Grove facility. In the summer, 5 million gallons of water are cleaned each day at Forest Grove and then Fernhill before flowing to the Tualatin River.
Located near the confluence of Gales Creek and the Tualatin River and just minutes from downtown Forest Grove, Fernhill is a great place to see the connections between water, plants, birds and wildlife. Visitors can enjoy the 1-mile loop around Fernhill Lake and the healing Water Garden. In addition to migratory birds, such as shore birds and waterfowl, the site attracts herons, hawks and beavers.

The parking lot, trails, picnic, shelter and restrooms are open to the public from dawn to dusk. Fernhill also contains a bike hub consisting of maps
