Analysis

After several unsuccessful attempts to takeoff from a snow-covered lake, the plt found a plowed area leading to a fish house. He taxied to the area and began to takeoff towards the east. On lift-off, the left aileron struck the top of the fish house. The plt landed about 50 yards beyond the fish house without further incident.
