About Dexter
Dexter State Recreation Site sits on the shores of Dexter Reservoir in the Cascade foothills east of Eugene. The reservoir is the lowest of three dams on the Middle Fork Willamette River (Dexter, Lookout Point, and Hills Creek). The warm water and protected shores make it one of the best swimming and waterskiing lakes in the southern Willamette Valley.
Things to Do
Swimming, waterskiing, fishing for bass, trout, and panfish, and picnicking along the lakeshore. A boat ramp provides easy lake access. The lakeside picnic area is shaded by Oregon white oaks and Douglas firs. The adjacent Lowell Covered Bridge is one of the longest covered bridges in Oregon.

Frequently Asked Questions
How many covered bridges does Oregon have?
Oregon has 50+ covered bridges — more than any state west of the Mississippi. Lane County alone has 20. These bridges were covered to protect the wooden structure from Oregon’s heavy rain. Many date to the early 1900s.
Wildlife & Nature
Dexter State Recreation Site sits along Dexter Reservoir — the lowest in a chain of three reservoirs (Hills Creek, Lookout Point, and Dexter) on the Middle Fork Willamette River. The reservoirs provide flood control for the Willamette Valley and create important recreation opportunities. The warm, shallow Dexter pool attracts wintering waterfowl — trumpeter swans, tundra swans, and cackling geese are regular visitors. Bald eagles fish the reservoir and nest along its forested shores. Osprey platforms support nesting fish hawks throughout the summer. The surrounding foothills transition from Willamette Valley agriculture to Cascade Range forest — creating edge habitat that supports maximum wildlife diversity including black-tailed deer, wild turkeys, and Roosevelt elk.
Nearby Attractions
Lookout Point Lake and Hills Creek Reservoir extend the recreation chain upstream into increasingly wild Cascade terrain.
