Elkhorn will be no more??? come on. Not saying it will good or bad for fishing but in most of elkhorn I dont think the flow is affected much by the dams. The only part it would impact is North Elkhorn. I think it will make the smallmouth fishing better but it will be harder to float in any size boat. South Elkhorn doesnt have any dams and its fine. You just have to wade in the summer. Unless your into fishing the bigger holes above the dams my guess is it wont matter much.
