G. D A table has been constructed giving the totalamount of run-off measured at the place wherethe seven years gagings were taken (abovewhich there is a catchment area of squaremiles), together with the difference betweenthis amount and that derived from the 115square miles above the Coyote Reservoir. Thisdifference gives an average of about 28 M. G. D.,which is carried on down into Santa Clara Val-ley. The table on Plate F-3 shows the fre-quency and amounts of the waste over the 23-year period. The sum of these wastes makes anaverage total of 45 M. G. D. going into the val-ley below. An analysis of the table of gagings shows amean discharge for the seven years of G. D., with a rainfall of inches, or amean seasonal run-off of inches. The meanin inches for the 23 years is inches witha rainfall of 434 Na WATERSHEDSUBD/V/S/O/VS CATCfiMENTAREA/NCT^.
