Dexter is an unincorporated community in Lane County, Oregon, United States. It is located near Dexter Reservoir, a.k.a. Dexter Lake, a reservoir of the Middle Fork Willamette River along Oregon Route 58.
Access to Dexter Lake, a popular fishing and boating site, is available at Dexter State Recreation Site. The nearby Dexter Lake Club was used in the filming of the road trip scene in the movie Animal House.
Dexter Lake supports populations of rainbow trout, largemouth bass, and smallmouth bass. The lake also has large populations of northern pikeminnow. The City of Lowell encourages removal of this rough fish during a pikeminnow contest held each July.
