Cattail Bay Access on Lake Oahe features a boat ramp that was widened to double-lane capacity to reduce congestion and improve launching efficiency, particularly during peak fishing season when the area experiences heavy use (averaging over 20,000 vehicles annually).

The recreation area includes 13 primitive campsites, a courtesy dock, fish cleaning station, vault toilets, and a large gravel parking area. Access is via a gravel road approximately 5 miles from Highway 1804 near Strasburg, North Dakota.
