Description
See *Idaho: the Whitewater State* by Grant Amaral.
Lat / Longitude data are *very* approximate.
Locals can speak to this run's annual characteristics in more detail, but with water flowing from the reservoir, this can occasionally be a terrific and technical summer run! It's also a perfect packrafting daytrip, hiking in from the beginning of the old road to wherever you want to put in. Wood is the biggest danger and there is plenty of it, with reports of some folks doing dozens of portages depending on when you catch it in the season. If you're lucky and the local stewards have already cleared wood during the spring, you will be rewarded with an 8-9mi backcountry paddle with two pockets of continuous, splashy Class III-IV. The top has the most rapids and they are consequential with all the wood in the waterway – and potentially long if you swim. There are several miles in the middle that are placid Class I-II. The end has a shorter section of flumes that are similar to the top, Class III with IV consequences.
This run requires solid judgement and boat control. Know your crew, know your limits!
