Now Coho (Silver) Salmon don't get quite as big as the Chinook, but they are incredible fighters and in a class all by themselves, from 100 ft. down they like to rocket to the surface and go airborne. This year the average has been between 12-14 pounds for these guys. The world record was set August 13th, 1998 from Lake Ontario of 33.7 pounds.

If Brown Trout are what you are looking for then how about 8-10 lb's being average with frequent 20 pounders. The only way to describe them is Fat and Feisty with an attitude.
Then there's the Steelhead, "Good Eatin'" doesn't begin to describe these tailwalking acrobats. They can out fight an Atlantic Salmon, with the State record being 26 lbs. 15 ozs.(Salmon River). The average would be in the 8 to 10 lb. range.

Lake Trout (Togue) State Record is 39 lbs. 8 ozs.(monster trout). The average is about 8-10 lbs. These guys like the cold temperatures and are usually found down deep near the bottom.
