During periods when there is boatable flows in this reach there appears to be a lot flow coming in from side streams. So actual flow in the reach can be much higher than the release from Milton. Inflows to Our House Reservoir became available in June 2010.

Preliminary reports indicate that 600 to 800 cfs below Milton is a good flow range, while 1,000 cfs is getting pushy.
USGS Yuba Schematic pdf shows reservoirs, diversions and gauges in the North and Middle Yuba drainages.
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. Flows from sidestreams below Milton are collected at Our House and diverted through the Lohman Ridge Tunnell, eventully reaching Bullards Bar Reservoir on the NF Yuba.
Historical gauge data is available for:
Milton Bowman Tunnel - USGS 11408000 Diversions can be as high as 490 cfs.
Lohman Ridge Tunnel - USGS 11408870 Can divert as much as 850 cfs.
MF Yuba below Milton Dam - USGS 11408550
Jackson Meadows Storage 66,700 acre/feet of storage.
