River Description


Messages  at Boof.com imply that this section has had exploratory descents, but otherwise there has been very little information about this section of river.  It was kayaked in 2008 and a trip report is linked below. 

Aerial photos on the map tab show that much of this section is low gradient separated by usually short sections of falls or cascades.    One long section of boulders and cascades squeezed between major cliffs, appears to be a significant obstacle.  

Take out:  Early Intake is only a few miles away from Holm Powerhouse, the put in for the regular Cherry creek run.   From Highway 120 near Colfax Spring, find the Cherry Lake Rd, (Forest Rd 1N07).     It is unclear if the best take-out is on the small reservoir at Early Intake or upstream near where the road makes a switchback.  

Put in:   From the take out, backtrack a short ways to Forest Rd. 1S02, Mather Road.    Take this road east through Mather to Hetch Hetchy.   There is a parking lot near the dam.   From the dam side of the parking area, a dirt road leads back downstream to a bridge over the river.    This road may be gated.

Gauge Description


Hetch Hetchy reservoir spills during the spring of many years.   Most spill flows will probably be too high for boating in this section, so your best bet will be at the very beginning and the very end of spill.    There is a USGS gauge available for this section.    Ben Stookesbury reported after a 2008 trip that he would have prefered more than 200 cfs, but not a lot more.

ACTION ALERT–Help to open Yosemite to boating!

2013-02-08 13:46:00-05
Megan Hooker

Yosemite National Park is currently seeking the public's input on how the Wild and Scenic Merced and Tuolumne Rivers will be managed in the future, including the question of whether to open them up to paddling. While we're pleased to see the park is considering lifing the ban in some areas, the preferred alternative for both rivers keeps the long-standing prohibition on paddling in place for the Tuolumne and on sections of the Merced. With your help, we can advocate more effectively for opening these stunning and amazing rivers to the public!

Yosemite Releases Tuolumne River Plan

2014-03-21 17:45:00-04
Megan Hooker

On Friday, March 14th, Yosemite National Park released their Final Tuolumne Wild and Scenic River Final Comprehensive Management Plan and Environmental Impact Statement, announcing that boaters will have the opportunity to enjoy the Grand Canyon of the Tuolumne by kayak on a trial basis. While we’re pleased that the Park has placed boating on equal footing for this reach, we're disappointed that the plan continues to prohibit boating on the rest of the river.
