Pilot Report
The pilot reported that at the departure point, the weather consisted of a 1,500 ft broken ceiling, visibility of 20 miles, and wind from the southwest at 5 to 10 knots. After taking off in a float plane, the pilot elected to follow a slough.
Encounter with Rain
Approximately 1.5 miles from the departure point, after turning a corner, the pilot flew into heavy rain showers. Because of hilly terrain adjacent to the slough, the pilot chose to continue following it rather than climbing. The pilot stated that the intention was to fly low until having flown through the rain shower.
Decision to Land
The pilot then came to a sharp turn in the slough and elected to land. The landing was normal except that the aircraft was about 10 knots fast during touchdown. The pilot was unable to slow the aircraft enough to prevent contacting the shoreline bank.
