Ya I knew of some spots before the flood. With all the work and the damage you prolly just wann avoid the canyon totally. If you drive towards logn mont on 66 there's a large pond it will be on your right (mccall lake) that's an ok spot for some worm drownding. There's rainbows in there and a number of warm water species. That's one of the only places that comes to mind right around lyons without the river.
