~ ~ r= -20- .- reservoir. It is zero when a Juniper call is in effect. In months in which Juniper Reservoir filled during the month (both "yes" and "no" checked in Col. 7) then this column reflects a 100% fill rate for the time that the Juniper call is off. The percentage of time that the call is off is determined by dividing streamflow which is left over after satisfying direct flow requriements and .filling the Juniper Reservoir (Col. 1 - Col. 2 _ Col. 4) by the total streamflow (Col. 1).

Column 11 - Hinman Park Reservoir augmentation release. This release is based on the assumption that the Saddle Moun- ------ tain Pump Station consumptively uses 50% of its 65 cfs year-round requirement and that this consumptive use must be augmented by releases f~m the Hinman Park Reser- voir when Juniper has placed a call on the river. In addition, a 6% stream loss is charged to the releases. In months during which Juniper Reservoir fills to cap- acity, augmentation water is released only during that portion of the month when the Juniper call is on.
