Analysis

During a lake takeoff at near lift off speed the plt stated the acft struck a submerged log and became airborne at a low airspeed. The acft then dropped back to the lake surface, the right wing float dug in the water and separated the float from the wing. The stress also caused partial wing separation at the wing root. Loss of the float resulted in the acft rolling inverted.
