Diversion Season (DS) Minimum Bypass Flow (MBF) Maximum Cumulative Diversion (MCD)
DS1. MBF1. MCD1.
12/15 - 3/31 February median daily flow MCD Rate = 15% of 20% Winter (12/15-
3/31) exceedance flow
DS2. MBF2. MCD2.
Year Round 10% Exceedance Flow MCD Rate = 5% of 1.5 yr flood peak flow
DS3. MBF3. MCD3.
10/1 - 3/31 Drainage Area (DA) < 290 mi 2 :
Q MBF = 8.7 Q m (DA) -0.47
Drainage Area > 290 mi 2 :
Q MBF = 0.6 Q m
Q m = unimpaired mean annual flow (cfs);
For streams above anadromous habitat, DA is
determined at the upper limit of anadromy
MBF4.
Drainage Area < 0.11 mi 2 :
Q MBF = 8.7 Qm (DA) -0.47
Drainage Area = 0.11-500 mi 2 :
Q MBF = 5.1 Q m (DA) -0.71
Drainage Area 500 mi 2 :
Q MBF = 0.06 Q m
For streams above anadromous habitat, DA is
determined at the upper limit of anadromy

MCD Volume = 10% estimated
unimpaired flow (no restriction on
diversion rate)
MCD4.
MCD Rate = diversion rate which
results in a maximum reduction of the
time flow is above the MBF to 1 / 2 day
during a 1.5 yr flood event
