Mongold Day-use Area features Oregon's only public boat launch facility on Detroit Lake, with a large paved four-lane ramp, seasonal courtesy dock, and low-water winter ramp to accommodate seasonal lake level changes.

The facility offers 83 single-car parking spaces and 120 RV/trailer parking spaces, plus amenities including a swim area, picnic facilities, restrooms, and a life jacket loaner station.

Note that overhanging tree branches along the launch road may pose clearance issues for boats with raised masts, and a day-use parking permit is required year-round.
