Missouri River/Lake Oahe Boat Ramp Status

High water levels on the Missouri River have closed or restricted access at numerous public boat ramps, specifically in the Bismarck/Mandan and Williston areas.

Bob Frohlich, North Dakota Game and Fish Department fisheries development supervisor, said high releases from Garrison Dam have led to the closure of Cross Ranch (Sanger), Hoge Island, Grant Marsh Bridge, Fox Island and Little Heart Bottoms ramps, and high flows coming from the Yellowstone River have inundated and closed the Highway 85 boat ramp near Williston.

“In addition, several other boat ramps are nearly submerged due to high water levels,” Frohlich said. “Although they remain open at this time, exercise caution and care when using these sites.”

Due to high flows forecasted well into summer, Frohlich said the affected public boating access areas in the Bismarck/Mandan area will likely remain unusable for an extended time.

Game and Fish will post ramp status updates as they occur on the department’s website, gf.nd.gov.
