Madison

Because of dam maintenance at Hebgen Lake, the water level at Quake Attack is the highest I have seen. It has been ranging between 3200 cfs and 3800 cfs. The character of the river demands full attention and endurance at these flows, as it more resembles a North Fork Payette than a Madison River Run. Although the majority of the rocks are underwater, they are still sharp and will leave a strong impression should you decide to face off with them. If you are in the area, it's worth a trip to look at it, as it is very easy to scout from the road and there are eddies above the S-turn rapid for an easy portage. It's a great run that demands your respect and attention to safety.
