3 men were floating the Yellowstone River in a drift boat.  The boat struck an object in the river (rock?) and the boat began taking on water.  All three men were thrown from the boat.  One man held onto the boat and floated with it to an island and another man swam to the shore.  victim was unable to overcome the current that pulled him under the surface.   He was found at about 9:30 that evening in about 10 feet of water.
