I fish Stripers and lake trout in the lake and the stripers eat more Alewife's and shad than trout, The Lake Trout do very well so why rainbow would not survive is beyond me, but I just fish what do I know, The fish commission says brown trout and rainbows wont survive in the creek behind my house because the water is too warm, I am not sure what Kool Aid they drink but I catch them all the time, big browns and Rainbows so what do I know. And the bass fisherman told me 40 years ago the muskie would eat all the bass, Well the muskies are still there and so are the bass, I think Smolts would do very well in trough creek, How about it Fish Co, give it a try.
