Sec. 418.18  Diversions at Derby Dam.

    (a) Diversions of Truckee River water at Derby Dam must be managed 
to maintain minimum terminal flow to Lahontan Reservoir or the Carson 
River except where this part specifically permits diversions.
    (b) Diversions to the Truckee Canal must be managed to achieve an 
average terminal flow of 20 cfs or less during times when diversions to 
Lahontan Reservoir are not allowed (the flows must be averaged over the 
total time diversions are not allowed in that calendar year; i.e., if 
flows are not allowed in July and August and then are allowed in 
September then not allowed in October and November, the average flow 
will be averaged over the four months of July, August, October, and 
November).
    (c) The Bureau will work cooperatively with the District on 
monitoring the flows at the USGS gage on the Truckee Canal near Hazen to 
determine if and when flows are in excess of those needed in accord with 
this part and bringing the flows back into compliance when excessive.
    (d) Increases in canal diversions which would reduce Truckee River 
flows below Derby Dam by more than 20 percent in a 24-hour period will 
not be allowed when Truckee River flow, as measured by the gauge below 
Derby Dam, is less than or equal to 100 cfs.
    (e) Diversions to the Truckee Canal will be coordinated with 
releases from Stampede Reservoir and other reservoirs, in cooperation 
with the Federal Water Master, to minimize fluctuations in the Truckee 
River below Derby Dam in order to meet annual flow regimes established 
by the United States Fish and Wildlife Service for listed species in the 
lower Truckee River.
