No offense Joe B but I don't think the viabilty of the native fish to this river drainage was the issue. The walleyes in the lake 20 years after impoundment that were caught would dispute that notion, and the spawning ideal would be compared to the stripers,they don't. As to if native walleye could spawn in the lake,there are still sauger in the lake as of today and the state record sauger was caught in 1983 at the lower end of the lake and you can catch them as of today, and the strain from here is still claimed to be in the drainage of the lake. I know it is a money issue, but in the long run I cannot see how it is not better to stock the native strain fish that evolved here and adapted to the conditions that are here.
