I?m interested in the difference in fishing related ecology between Lake Granby and Lake Grand. Does Grand have the same relative numbers of Lake Trout, Rainbows or Browns? Is one lake more suited to fly fishing or very deep-water fishing?
I'd call budget tackle in Granby, most of the time they know what is happening in that area. Both are great for smaller lake trout and rainbow. Granby would probably be better better suited for finding shallow fish with fly in hand.
