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

The private pilot reported he was flying his single engine float-equipped airplane at low level in carburetor icing conditions with the carburetor heat approximately 60% "on." He said he applied power to climb, but the engine would not initially respond, and then ran rough. He applied all the carburetor heat, but the engine "choked" and lost more power. He made a forced landing in a nearby swamp, and the airplane nosed over. After the airplane was removed from the swamp, the pilot said the airplane's engine started and ran fine. The pilot noted in his report to the NTSB that the accident could have been prevented by the early detection of carburetor ice, and application of carburetor heat.
