For people who find this interesting I would highly recommend the book Emerald Mile [0]. Amazingly well written book about glen canyon, grand canyon, lake powell, glen canyon dam, dorys people, racing boats down the canyon and a near catastrophe in the dam building.
Also lets not forget the classic Desert Solitaire [1]. It too is well written and very interesting, in the book they take small inflatable boats and just float down Glen Canyon not long before it gets flooded.
