Wilderness Landscape & Natural Heritage
Scoggins Valley State Park encompasses over 1,100 acres surrounding Henry Hagg Lake, a man-made reservoir formed by Scoggins Dam on the Tualatin River. Located in the northwest part of Oregon's Willamette Valley, the park features a mix of forested hills, open meadows, and lakeshore habitats. The area is home to Douglas-fir and western red cedar trees, providing habitat for black-tailed deer, waterfowl, and various other wildlife species. Originally managed to support regional water supply and flood control, the park now draws outdoor enthusiasts for its diverse recreational opportunities. Visitors can enjoy extensive boating and fishing on Henry Hagg Lake, with populations of trout, bass, bluegill, and catfish. The park's trail system includes multi-use paths for both hikers and mountain bikers, allowing visitors to explore forested slopes and ridge tops with scenic views of the lake and surrounding hills. Popular spots include the lake's boat ramps and picnic areas, as well as designated camping zones that accommodate tents and RVs. The park is managed by the Oregon Parks and Recreation Department and is accessible year-round, attracting locals and visitors looking for day use or overnight stays in a natural setting close to Portland and other urban centers. Its combination of water-based activities and land trails makes Scoggins Valley State Park a favored destination for family outings, fishing trips, and mountain biking excursions.
