Yosemite Allows Boating in Grand Canyon of the Tuolumne
Kayaking on this class V section will be permitted, and the management team there sounds quite reasonable about letting management evolve along with use. The use of this river section can be revoked if there is any paddling on Hetch Hetchy Reservoir, where boating is banned.
The run will start at Pothole Dome below Tuolumne Meadows and end at Pate Valley. Exact details about put-in, take-out, portage trails and landing/no-landing zone locations will be determined in the near future in consultation with the boating community, tribal interests and National Park Service resource experts. Boaters making the run will be required to carry their boats 3 miles to the put-in, and carry them 8 miles from the take-out at Pate Valley to the White Wolf trailhead.
Carrying your kayak 11 miles is hard. The info does not indicate that this section of river is a series of long slides over domes of granite. I do not know if anyone has been running it lately, but I do remember that Lars Holbek carried his boat most of the way and didn't want to do it again. I have HIKED down the Grand Canyon of the Tuolumne on a 3 day backpacking trip, and it was spectacular. A backpack trip might be a good way to scout the whitewater before committing in a boat. Though it is possible that those California boaters think nothing of this stuff. Looks hair to me.
