sent in a reply to this item yesterday but the internet gods must have eaten it ,. YES there are landlocked coho , also Pinks and Chinooks ( wish there were sock as well ) . They are all found in the great lakes , the first plantings were by some of the states and after much pressure from fishermen Ontario started stocking them as well ( that is coho and chinook ) and there are significant populations in all the great lakes with some real good runs in some of the rivers .They don't get as large as those in BC but 25 to 40 plus pounders are available. The pinks are a different thing as the stocking wsa accidental . The Ontario M.N.R. obtained some pink eggs with plans to establish a population in James Bay however the hatchery truck taking them to the aircraft had problems so the driver released the smolts into a stream running into Lake Superior and loand behold they took hold and there have been a self sustaining population in Lake Superior , Lake Huron and I beleive Lake Michigan for many years . The most unusual thing is that to establish an exotic population with only one accidental stocking is almost unheard of .
