All flows are in cfs.

Delta Gross Channel Depletions - from Dayflow table 4.

Rio Vista Flow - calculated from Dayflow equation.

QWEST - calculated from Dayflow equation.

Net Delta Ouflow Index - calculated from equation as specified in D-1641, revised June 1995.

Conditions:

c=excess Delta conditions

b=balanced Delta cond. w/ no storage withdrawal

s=balanced Delta cond. w/ storage withdrawal

Excess Delta conditions with restrictions: f=fish concerns r=E/ I ratio concerns
