Officials at Muskogee War Memorial Park said the Oklahoma Department of Emergency Management and the National Guard took over the site Friday due to severe flooding.
The park is home to the USS Batfish, a World War II-era submarine that now serves as a museum.
Park staff and volunteers are being used to support emergency officials in managing the scene.
Officials said at least one line on the Batfish has broken and they are working to keep it from floating away.
Crews are filling the ballast tanks on board the USS Batfish to keep it inside the park's bowl. The National Guard also tied a new line to the boat to add leverage.
