This is one impressive rapid. You will know you have reached Rainbow Falls when you see a big horizon line. Scout/portage this one on river left. If you get out early enough above the first drop you will avoid walking over a bunch of downed trees (thanks Dennis). It starts with a 10-12 foot waterfall, then a large slide, a small pool of swirling water, another slide thing and then a big waterfall into a deep gorge. After the waterfall the river enters the gorge and turns 90 degrees to the left causing some interesting looking currents. Rainbow Falls has been run but not by many. There is a trail on river left that will get you down into the gorge so if you decide to forgo Rainbow falls you can still run the gorge. It may be easiest to lower the boats by rope. I didn't know how to rate this one. It has been run but most portage it. We will call it a 5.1.
The gauge is actually on the West Branch of the Oswegatchie so it should be used as a guide only. There is not a gauge on the Middle Branch.
Permits are not required for this reach.
We have no additional detail on this route.
