They don't reproduce in the streams. They "spawn",but the eggs never develop into fry as the water warms in the summer. In essence it's an artificial fisheries kept going by extensive stocking. It's a money maker for the state,but the fish aren't edible unless taken fresh in the lake . The PCB levels in them are such that 1 meal a month is recommended. They also heavily stock brown trout and rainbows/steelhead for winter "spawn" fishery. The creeks they run up are to warm to support a viable self sustaining fisheries. The initial salmon were stocked in Lake Michigan to combat Alewives which were a pest in the Great lakes. Success there prompted other states to plant salmon and later steelheads and in Lake Ontario browns. Don't get me wrong it's a great fisheries that I have enjoyed for years. Innaaa, where did you fish? The Salmon River?
