Opitz Public Boat Ramp is a primitive boat launch with a landing dock located 5 miles west and 1 mile south of Eden, South Dakota on Opitz Lake.

High water conditions have limited public access to this single access site, making it the only public boat launch available on the 1,436-acre lake.

The ramp provides access to a well-managed walleye and yellow perch fishery across the lake's 23-foot maximum depth.
