2014 YUBA COUNTY WATER AGENCY WHITEWATER BOATING FLOW STUDY
River: Middle Yuba River
Reach of Interest: Highway 49 to Englebright Reservoir
Project: Yuba River Development Project (or YCWA)
YCWA is collaborating with interested stakeholders including American Whitewater (AW), Tahoe National Forest, and the National Park Service to identify a preferred range of whitewater boating flows on the Middle Yuba River downstream of Highway 49 in 2014. YCWA’s Yuba River Development Project is undergoing relicensing (Integrated License Process) with the Federal Energy Regulatory Commission (FERC). For more information on YCWA’s relicensing, please visit the public relicensing website at: http://www.ycwa-relicensing.com.
Study Reach Information – MYR from Highway 49 to Englebright Reservoir
Put-In: Highway 49 bridge (3 mi. north of the town of North San Juan)
Takeout(s): Option 1: Colgate Powerhouse (river right via town of Dobbins; Option 2: Rice’s Crossing (on river left via dirt road heading north at Bridgeport State Park)
Target Flows: Hardshell Kayak = 600-1,200 cfs / Raft = 1,000-1,200 cfs
Flow Gages: MYR above Our House; and MYR below Our House.
Boater Evaluation Form Process
Information from the boater evaluation forms will help YCWA identify a flow preference curve for whitewater boating, which will identify minimum acceptable and optimum flows. The data collection requires 3 key steps: Step 1 - Boaters run a reach at a min. of 2 flows in the target range (3 flows preferred) for a craft. Step 2 - Following each run at a different flow, the boater will complete a 1-page, Post-Run Evaluation Form – either a hard copy version as distributed by AW or online (see link below). And, Step 3, once a boater has run a reach a min. of 2 flows in the target range for a craft type (3 flows preferred), then the boater will need to complete a final Comparative Evaluation Form that identifies the minimum acceptable flow and optimal flow range for the reach (hard copy or online). Note: the online link to the Comparative Evaluation Form will be provided once a boater has completed a min. of 2 flows.

Please review the flow level before and after each run to determine what the actual flow was that you boated before submitting the survey, if possible. At the very least, be sure to accurately record the date and times of your trip so that flows may be determined using the flow history. Please take photos and upload them to the AW photo database.

|Mile||Rapid Name||Class||Features (Legend)|
Long bouldery rapid
There will be some additional water coming down the NF, but usually not very much. Dirt roads or trails lead up the hill to the north towards Marysville Road and Bullards Bar dam.
This pretty big rapid starts immediately after the confluence with the NF.
Narrow canyon, big boulders. Big rapids come one after another for several miles, only easing off near Colgate powerhouse
Water from Bullards Bar reservoir is released from this powerhouse on river right. A paved road leads up to Marysville road in 4.4 miles.
Below this point, rapids appear to be only gravel bar.
The remains of on old bridge mark Rice's Crossing. Take out on river left. A dirt road leads up to Bridgeport.
