Boundary Reservoir Access provides boat launch facilities at Seattle City Light's Forebay Recreation Area near Boundary Dam, offering access to a 1,579-acre reservoir on the Pend Oreille River with year-round fishing opportunities.

The area features a well-maintained free campground with 22 camping sites, flush toilets, potable water, picnic areas, and a fishing dock, making it an excellent base for both boating and fishing activities.

Water levels and flows are subject to extreme and unexpected changes, so boaters should be alert for dangerous currents, rapids, and debris.
