------------------------------------------- total April-July Adjustment = 1231 kaf
Of the April-July unimpaired (or natural) average of 4165 kaf, 1231 kaf or
approximately 30 percent of that total is diverted or stored in reservoirs
on the average (any given year likely will be different). A much smaller
volume therefore would be expected actually to flow by the Cisco gauge from
April 1 to July 31 (the observed or regulated flow). A schematic
illustrating these adjustments for the Cisco forecast is shown on the
following page.
