Ofj30:~3 THE IMPACT O~ THE ADDITION or PROJECT WATER TO THE ORIGINAL WATER SuPPLY FOR THE DISTRICT AREA IS CLEARLY EVIDENT FROM THE ABOVE DATA. By APPLYING A LITTLE ARITHMETIC TO . THE BASIC r/GURES IN THE TABULATION1 THE FOLLOWING INTERESTING RELATIONSHIPS CAN BE DERIVED: 1928-1937 AI,IGE. A.F. 1958- 1967 AVGE:. A.F. FOR EACH ACRE-rOOT or TOTAL PRIMARY WATER SUPPLY: TOTAL DIVERSIONS IN DISTRICT= SURFACE DIVERSIONS IN DISTRICT= GROUND WATeR PUMPAGe:= TOTAL RETURN fLOW= RETURN FLOW RE-USED IN DISTRICT= OUTFLOW TO NEBRASKA= CONSUMFTiVE USE= 2.2 2.1 .1 1.5 1.2 .3 .7 2.5 1.5 1.0 1.8 1.5 .3 .7 FOR EACH ACRE-FOOT OF INCREASED PRIMARY SuPPLY: ~ TOTAL DIVERSIONS INCLUDING OUTFLOW INCREASED TOTAL DIVERSIONS WITHIN DISTRICT INCREASED SURFACE DIVERSIONS WITHIN DISTRICT DECREASED GROUND WATER PUMPAGt INCREASED TOTAL RETURN FLOW INCREASED CONSUMPTIVE USE INCREASED OUTFLOW TO NEBRASKA INCREASED 3.8 3.3 .1 3.4 2.8 .4 .5 ., THESE FIGURES SHOW THAT TOTAL WATER USCAG' IN TH' DISTRJCT INCREASED ).3 ACRE-FEET FOR EACH ACRE-FOOT or INCREASED PRIMARY SUPPLY. OUTFLOW TO NEBRASKA WAS ALSO INCREASED BY ONE-HALF ACRE-FOOT FOR EACH ACRE-FOOT OF INCREASED SUPPLY. NOT ALL of THE INCREASED USE CAN BE ATTRIBUTED TO PROJECT DELIVERIES, OF COURSE; BUT MUCH OF IT CAN BE. TOTAL USE IN THE 1928-1937 PERIOD AVERAGED 2.2 TIMES THE PRIMARY SUPPLY. THEREFORE. r TIS SAf"E TO SAY THAT AT LEAST 2.2 uSES HAVE BEEN MADE OF PROJECT WATER DELIVERED. ON THIS BASIS. THE AVERAGE, ANNUAL TOTAL USAGE ATTRIBUTABLE TO PROJECT WATER IS AT LEAST 526.000 ACRE-FEET. THIS SHOWS THAT THE ORIGINAL PURPOSE FOR THE CREATION OF THE DISTRICT AND FOR THE CONSTRUC- TION OF THE COLORADO-BIG THOMPSON PRO~ECT IS BEING LARGELY FULFILLED. . . -5-
