⁽⁵⁾Computed inflow to Heron Reservoir=Tributary inflow above Heron Reservoir. Times correlation factor (1.2 for monthly Willow Creek natural flow above 360AF and 2.46 for flow at 360AF and below. If the inflow does not exceed the seepage this flow is not bypassed. Flows above the seepage are bypassed.)
⁽⁶⁾This column reports the seepage 2(4) as the base natural flow or the net gain on reservoir 2(3) which ever is greater or zero when 2(3) is zero and 1(5) is more than seepage. (See table 2)
⁽⁷⁾This column reports the sum of 1(5) and 1(6) only when 1(5) exceeds the seepage. This will prevent any double accounting of the base natural flow (seepage). If 1(5) is less than or equal to seepage then 1(7) equals 1(6).
