Narrative:

While taking off from a lake I was forced back in the water after takeoff by wind (downdraft). I aborted my takeoff; shut down the airplane and hit the bank at the opposite end of the lake. Nobody was hurt. The shore of the lake is rocky and I put a tear in the bottom of my right float and a dent in my spreader bar. After several attempts to reach some help on radios I temporarily repaired the float and flew the plane back to ZZZ alone. I had no ferry permit to do this. 1) taking off from a short lake on a windy day. 2) not having a way to contact someone from a remote location. 3) not filing a flight plan. 4) after being there several days I wanted to get home. 5) being new to this lake I misjudged the effects of mountain winds.
