According to the web page THE DRIVE (https://www.thedrive...me-in-decadesin Oklahoma)
"The historic World War II submarine USS Batfish has re-floated once again nearly fifty years after it was dry docked on display in a park along the Arkansas River.
Aerial video from KOTV News on 6 shows the USS Batfish floating comfortably in at least 15 feet of water on Wednesday as the Arkansas spills over its banks and swamps the city of Muskogee. Normally, the 77-year-old Balao-class submarine serves as the centerpiece for Muskogee's War Memorial Park, standing bare on a bowl-shaped lawn as both an interactive museum and a point of pride for the region. But these floodwaters have it sailing again like it's 1943.
The boat began to lift up as water filled the surrounding basin, prompting an evacuation of the museum while caretakers removed WWII-era artifacts for safekeeping. That decision seemed even wiser as the USS Batfish began to list as it floated ever-higher; local firefighters later filled its ballast tanks to level it out. It remains to be seen whether the old sub will stay watertight."
Below are pictures of the USS Batfish under normal conditions and now afloat.
