State conservation officials say a 60-foot tug sank in about 120 feet of water near Wrangell.
Authorities say the Silver Bay II was found missing Tuesday during a routine dock check by representatives of the Silver Bay Logging facility about five miles south of Wrangell.
The tug was estimated to have about 3,500 gallons of diesel fuel on board. The tug had been tied to the dock for five years, and much of the fuel had been removed during that time.
There’s a light sheen in the area, but no reported impact to wildlife. The Coast Guard is investigating.
