Seven people swam ashore after their plane crashed in Big Goat Lake.
The incident happened around 2:30 Sunday afternoon about 25 miles east-northeast of Ketchikan in the Misty Fjords National Monument.
Alaska State Troopers say the pilot, 30-year-old Matthew Perron, of Ketchikan, crashed his DeHavilland DHC-2 Beaver into the lake during takeoff.
Perron and his six passengers, from Germany and California, respectively, were all able to exit the aircraft and swim safely ashore. The passengers ranged in age from 30 to 63.
All of those on board were treated for minor injuries at a hospital in Ketchikan.
The FAA and NTSB have been notified of the crash.
