River Description


American Whitewater is partnering with Nevada Irrigation District (NID) and Pacific Gas and Electric Company (PG&E) to identify a preferred range of whitewater boating flows on numerous reaches in the Yuba and Bear watersheds. Information obtained from surveys completed by boaters will help us identify flow preferences for whitewater boating. Flow preferences determined from boater surveys will be used to evaluate possible effects on whitewater boating from Project operation and help define flow needs.

Boater input is very important to this process. Please help us, yourself, and your friends by filling out a survey if you paddle this reach.

North and Middle Yuba River Basins.pdf; Schematic of rivers, reservoirs, diversions, powerhouses and gauges.

Jackson Meadows Reservoir collects the headwaters run off and evens out the flow down the river to Milton Reservoir.   The Milton Bowman tunnel takes the water to Bowman Lake on Canyon Creek and eventually into the SF Yuba hydroelectric system.  Flows in the river below Milton are seldom higher than 5 cfs.   Only if Jackson Spills flows higher than the tunnel can accept, will some water flow into the natural river bed. 

Historical gauge data is available for:  
Milton Bowman Tunnel - USGS 11408000  Diversions can be as high as 490 cfs.
MF Yuba below Milton Dam - USGS 11408550 
Jackson Meadows Storage  66,700 acre/feet of storage.
