The Rattlesnake Lake is located outside the hydrologic boundaries of the Cedar River Watershed near North Bend. The lake is nearby Interstate 90, exit 32, about 3 miles southeast of North Bend and about 35 miles east of Seattle. The recreation area includes the 111-acre lake, picnic, and the Rattlesnake Lake Trail. There is parking access to miles of State Park and King County Parking along with King County biking, hiking, and horse trails. The recreational area is owned and managed as a non-development buffer by Seattle Public Utilities. This protects the watershed land surrounding Rattlesnake Lake. The watershed supplied 65% of the Seattle region’s unfiltered drinking water. This water is distributed to nearly 800,000 people and Rattlesnake Lake is not used for drinking water. It is spring-fed by the nearby cedar river.
