<br /><':j'< <br />oJ' <br />...~ <br /> <br />Summary and Allocation of Construction Costs <br /> <br />Total <br />In round figures <br /> <br />$ 1.5,000 <br />1,189,126 <br />41,000 <br />$1,24.5,126 <br />fl,24.5,000 <br /> <br />Examination and Surveys <br /> <br />Rifle Gap Reservoir <br />Grass Valley Canal <br /> <br />With one fourth of reservoir capacity allotted to improvement <br /> <br />of irrigation service for the Rifle Valley canals, a proportionate <br /> <br />part or 2.5~ of reservoir cOsts would be allocated to such canals <br /> <br />for repayment. <br /> <br />Annual Costs <br /> <br />The 6,000 acre project would receive an average 89~ supply <br /> <br />for the 10-year period of 1930-39. In periods of better run-off <br /> <br />the full 6,000 acres would be fully supplied each year. <br /> <br />With the Rifle Gap Plan, the reduction in maintenance costs <br /> <br />to be realized from reconstruction of the Grass Valley Canal, <br /> <br />and amounting to fully $1.500 per year, is expected to be about <br /> <br />offset by the increased cost of distributing water to the added <br /> <br />irrigated area, arrlounting to 2,400 acres. Operation and main- <br /> <br />tenance costs for the Riflp Gap reservoir are estimated at <br /> <br />$4,000 per year. <br /> <br />68 <br />
