However, the depletions have <br /> <br />been included in summarizing total depletions. <br />4. O'Neal Park Project. <br />This project, with various alternative plans~ was reported <br />in a Bureau of Reclamation Reconnaissance Report dated October, <br /> <br />1956. Results of that study indicate that the plans do not have <br /> <br />engineering feasibility because of an adverse cost-benefit ratio. <br /> <br />For planning purposes, however, it is deemed advisable to in- <br /> <br />corporate this project in the ultimate development of the San Juan <br /> <br /> <br />River in Colorado. For the purposes of this report it was assumed <br /> <br /> <br />that a diversion would be made from the Piedra River and its <br /> <br />tributaries to irrigate 5,800 acres of new land and provide supple- <br />mental water to 1,200 acres presently irrigated. The project <br />would deplete the flow of the San Juan River by an annual average <br />of about 6,800 acre feet. <br />It would be necessary to divert from tributaries other than <br />the main stem of the Piedra River because of water rights total- <br />ling 36.5 cfs in the vicinity of the diversion site. <br />5. Pine River Project Extension. <br />This project, as presented in the January, 1951 Project <br />Planming Report of the Bureau of Reclamation would provide water <br />for 14,520 acres of irrigable land in Colorado and 630 acres in <br />New Mexico. The stream depletion charged to Colorado would be <br /> <br />i <br />, <br /> <br />1- <br />.~, <br />"j; <br />
