Dude Ranch Boat Ramp is a popular access point on Lake Francis Case managed jointly by the Army Corps of Engineers and South Dakota Department of Game, Fish and Parks, featuring a boat ramp, fish cleaning station, picnic tables, and vault toilet.

Located just miles from Interstate 90 and Chamberlain, SD, it offers convenient access for boaters and anglers, though the dirt road in can be washboarded and rutted, particularly after rain.

The area operates on a first-come, first-served basis with a 7-day maximum stay limit and sees heavy use during weekends.
