Detroit Lake, Mongold Day Use Area

The North Santiam River was originally dammed in 1953 to provide flood control, electricity, and a consistent water source for the Willamette Valley.

Today, much of the original purpose of Detroit Lake is overshadowed by the fact that the reservoir is now one of Oregon’s most sought after summer recreation destinations, and Mongold Day Use Area (a State Park) is the 9-mile lake’s main access point for the general public.

Just west of Detroit Lake State Park Campground, Mongold Day Use Area features two broad boat ramps, a dock, the reservoir’s largest parking area (both trailer and vehicle), a well-shaded picnic area, restrooms and changing areas, and a designated swimming area.

Note: Overnight parking is permitted for boat-only access camping on Piety Island.  12 and 24-month day-use permits can be purchased at the entrance booth of Detroit Lake State Park or at any other state park office.
