The NTSB's narrative final · quoted from the NTSB record

The pilot stated he was hunting in the area and was returning to his base camp. He stated the lake was small, so he was step taxiing as close to shore as possible to gain the greatest amount of takeoff area. He felt the left float hit something submerged. The front of the float came up and struck the left wing struts and the left wing struck the water.
