River Description


 

Character: Mix of Bedrock and polished boulders. Long continuous rapids with multiple channels, big holes and sieves. Very few points of egress out of this canyon. That said, this is a world class run if you like class V+ river running. The first mile or so is warm up class IV. Then, its class V/.V+ all the way to the 49 bridge.  This run is a definite step or 2 up in difficulty and consequences from the Hwy 49 to Bridgeport run. It is similar in character to Cherry Creek (ending Merals pool) and Tobin on the NF Feather -- more Sieves and a little more continuous in places. 
Link this up with the section below, taking out at Bridgeport for one of the best ~12 miles of easily accessable whitewater in California!
Flow: 600 is a reasonable minimum level (locals would say 750). 750-900 is good -- padded with some push. >1000, the holes just keep getting bigger…>1400 -- pros only.    Easier at lower flows.
Winter: commonly runs from rain.  Spring/Summer: usually runs into June based on the snowpack. 
Hazards:  Serious sieves  and big holes throughout the run.   Strongly recommend you paddle w/ someone who knows this section of river or plan on a lot of scouting. 1) First portage is ~1.5 miles into the run after a long pool where the river bends sharply to the right. A deck is currently visible at river level and house sits high on the left bank. This rapid can be snuck thru a side channel on river left. 2) A broken dam about ½ way thru the run = Recirculating broken ledge hole. Sneek  left thru a side channel 3) River wide sieve ~1/2 mi to a mile below the dam (Not obvious). Portage/sneak left. 4) Sieve Rapid just upstream of hwy 49 pedestrian bridge. >95% of flow is sieved. Many swimming deaths have occurred here – Portage Left. ~Stay Safe!~

Success on the Yuba!

6/28/2012
Megan Hooker

Culminating a six-year effort, American Whitewater has reached significant flow agreements for the Yuba watershed. These agreements were memorialized in the amended license applications filed with FERC by the Nevada Irrigation District and Pacific Gas & Electric Company. We look forward to seeing you enjoying improved flows in the Yuba watershed!
