Checkmate, that lake is awesome. Most of the hazards are clearly marked. Are some rocks that are under water that look alot closer than they are because the water is so clear. The lake is so big it's hard to see during day trips. The best way to see lake is on a house boat. Dangling rope is at mile marker 40 and it has gas and is a fully stocked floating marina. At mile marker 46-48 is Rainbow bridge pretty cool to see. Down closer to wahweap is cookie jar bay that is nice area. I would buy a fold out Stan Jones map at the gift shop there. It gives you great detail for the whole lake. It's worth the money. Once yo go to Powell you never want to leave.
