The <br />three developments outlined in the report have been appraised <br />as potential participating projects of the Colorado River <br />Storage Project. The comprehensive and intermediate develop- <br />ments would provide for irrigation, hydroelectric power <br />production, fish and wildlife, and recreation. The small <br />development would serve all of these purposes except power <br />production. Under the comprehensive plan irrigation would <br />be provided for both existing and new farm units while in <br />the other plans irrigation would be provided only for presently <br />irrigated lands and undeveloped areas that could be farmed in <br />conjunctioq with existing units. Pertinent data on the three <br />plans are summarized below. <br /> <br /> Compr ehensi ve Intermediate Small <br /> develoDment development development <br />Irrigation service area (acres) <br />Full service 26,560 15,580 7,490 <br />Supplemental service 19,010 18,690 17.760 <br />Total 45,570 34, 270 25,250 <br />Power development <br />Installed capacity (kw.) 22,200 22,200 <br />Average annual generation <br />(1,000 kw.-hrs.) 76,236 76,236 <br />Costs <br />Construction costs $41,603,800 $36,720, 900 $7,079,500 <br />Annual operation, mainte- <br />nance, and replacement costs $178,600 $170,200 $65,040 <br />Benefits <br />Total benefits $2,132,200 $1,757,200 $683,400 <br />Direct benefits $1,601,200 $1,421,200 $441,700 <br />Benefit-cost ratios <br />Total benefits 1.29:1 1.20: 1 2.05:1 <br />Direct benefits only 0.97:1 0.97:1 1.32:1 <br />
