Study rapid

After a mile of mostly flatwater, cliffs develop, especially on the left. A group of large boulders block the channel. To scout, take out upstream on the right. At low flows the center slot is clean and the right side develops a route. At high flows the left side cleans up while the center develops into an ugly hole.

If the flow is below about 1500 cfs, rafters will have to portage this rapid by pulling their boats over the center boulder. At flows up to at least 2400 cfs, the center route is still good, while the left route is still shallow. At flows around 3,000 cfs and up, the left side route is better.
