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)
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)
Flow Gages: MYR above Our House; and MYR below Our House.

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.
FORECAST FOR WEEK OF 02/02/2015 – UPDATED as of 2/3/15 at 11 a.m.:
Based on NOAA’s California Nevada River Forecast for below Our House Diversion Dam, there is now some potential for flows in the boatable range. Refer to the flow forecast below from 2/3/15 at 8:48 a.m.
Notably, at this time, the current flow forecast is showing a rapid spike in flows in the middle of Friday night/early Saturday morning with additional precipitation expected on Saturday that may continue to increase flows. At this time, the forecast does not show if the flows will stabilize in the boatable range or when/how the flows will recede (slowly, quickly or at what time of day). YCWA will monitor the flow forecast provided by CNRFC twice daily and provide updates, as needed.
NOAA-California Nevada River Forecast: Middle Yuba River below Our House (OURC1)
Flows in this reach will usually be spill from Our House Dam. Oregon Creek provides additional water at the put in. At mile 4.6, the confluence with the NF, any releases from New Bullards Bar dam add to the flow. There has been one report that the gauge below Our House dam may be reading much too low. Boaters estimated flow at 4000 cfs when the gauge was only reading 1900 cfs (feb 2014, dreamflows message).

If someone gets hurt on a river, or you read about a whitewater-related injury, please report it to
American Whitewater. Don't worry about multiple submissions from other witnesses, as our safety
editors will turn multiple witness reports into a single unified accident report.
American Whitewater is advocating for improved access conditions at New Bullards Bar Dam on California’s Yuba River. Access to the sections of whitewater below New Bullards Bar Dam involves putting in at the base of the Dam; a 0.75-mile-long, paved, private, gated road (posted “No Trespassing”) accesses the base of New Bullards Bar Dam. Absent legal access below the Dam, boaters are required to hike around the dam, scramble down a steep and unstable hillside or to hike in from side roads, which Yuba County Water Agency (YWCA) considers as trespassing on their lands.
Log into the American Whitewater website and you can contribute to river descriptions,
flow and access tips, and maps associated with runs you've done. You can even add new
runs to the inventory!
