<br />. <br /> <br />. <br /> <br />.' <br /> <br />A~imas-La Plata Project, Colorado-New Mexico <br /> <br />/ <br /> <br />Possible use of a reservoir site on Cascade Creek or the Silverton <br />Resel~oir site in lieu of Teft are being studied. As a result of field <br />inspection by Regional and Denver personnel it was decided to proceed <br />with topographic surveys of the project lands in connection with detailed <br />drainage and land classification investigations. Specifications are being <br />prepared to obtain desired topography by photogrsmetric means if favOl'able <br />bids can be received. A memorandum of agreement with Bureau of Indian <br />Affairs for their financial participation in the investigation was drafted. <br /> <br />Dolores Project, Colorado-Utah <br /> <br />. Topographic surveys and field work for the detailed land classifica- <br />/ tion was carried forward. Deep holes were drilled and wells installed in <br />the McElmo area for drainage investigations. A memorandum of agreement <br />with the Indian Service for their financial participation in the investi- <br />gation was drafted. <br /> <br />Hammond Project, N~~ Mexico <br /> <br />A detailed land classification and drainage study of the project lands <br />was completed. About 8,000 acres were covered in the topographic surveys <br />with about 4,100 acres being classified as arable in classes 1, 2, 3, and 5. <br /> <br />O'Neal Park Project, Colorado <br /> <br />Reconnaissance studies are being made of the power potential on the <br />Piedra River above Piedra and of the irrigation potentialities north and <br />\lest of pagosa Springs. The most promising power plan appears to be a <br />reservoir of about 50,000 acre-feet at the First Box site, a tUnnel and <br />9,000 kilowatt powerplant. several sizes and plans for irrigation de'lel. <br />opment are being investigated. <br /> <br />Walker River Project, California-Nevada <br /> <br />Reconnaissance studies were completed outlining two plans of develop- <br />ment of different magnitude. The smaller or Hoye Canyon plan would pro- <br />vide irrigation and flood control benefits in the lower or Nevada portion <br />of the basin. The benefit-cost ratio for this plan would be 2.4 to 1 with <br />the irrigators being able to pay their share of the construction cost in <br />51 years. This is essentially the plan being considered by the Walker <br />River Irrigation District in Nevada. The larger or Pickle Meadows plan <br />would add hydroelectric power generation of about 20,500 kilowatts of <br />installed capacity and would provide somewhat greater irrigation and flood <br />development than the Hoye Canyon plan. The added benefits for prn~er irri- <br />gation, ~Hld flood control would be slightly greater than the added costs. <br />The overall benefit-cost ratio of the larger plan is estimated at 1.1 to 1 <br />with irrigators paying on their costs over 50 yearG..and the unpaid balance <br />to be repaid from net power revenues is an additional 4 years. <br /> <br />1.,,,... <br />'"OJ <br /> <br />4 <br />
