<br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />foe,.......... <br />v~~o <br /> <br />The lowest stage was reached on May 13, 1971, when the storage was 47,999 <br />acre-feet. <br /> <br />Inflow to Ruedi Reservoir during the May through July period was greater than <br />that predicted in the outlook for maximum probable conditions. It had been as- <br />sumed that the collection system would be in operation during those months and <br />inflow to Ruedi was reduced by estimated diversions to the Arkansas River Basin. <br />Actually, no Fryingpan-Arkansas project diversions were made as work under <br />the tunnel lining contract was not complete and the decision had been made not <br />to interrupt the work in progress to divert the water. <br /> <br />The total volume of inflow to ,Ruedi Reservoir during the spring runoff season <br />was 116 percent of that anticipated in the 1971 outlook under most probable con- <br />ditions if project diversions are added back. The monthly pattern varied from <br />that assumed. The runoff was late starting, resulting in a much lower May in- <br />flow and a much higher June and July inflow. <br /> <br />The ice cover on Ruedi Reservoir melted early in 1971 while the water surface <br />was below desirable levels for use of the Forest Service boat ramp. As a result, <br />numerous complaints were received by the Forest Service from local recreation <br />interests. The elevation of the bottom of the Forest Service boat ramp is 7704. 0 <br />at which elevation the storage is 51,803 acre-feet. Storage was up to this eleva- <br />tion by May 20. <br /> <br />On July 1, 1971, Ruedi Reservoir storage was 101,316 acre-feet. By July 5, <br />storage had reached a maximum for the year at 103,010 acre-feet. This storage <br />content has a corresponding water surface elevation of 7766. 64 or 0.64 foot above <br />the spillway crest. <br /> <br />A minor variation was made from the estimated plan of operation in August. At <br />the request of the Colorado State Game, Fish and Parks Department, the release <br />from Ruedi Reservoir was reduced to 50 c. f. s. for two 5-day periods to allow <br />electrofishing of the Fryingpan River. This electrofishing was for fish counting <br />and tagging as a part of a migration and spawning study. <br /> <br />On October 1, 1971, there was 100,250 acre-feetin storage in Ruedi Reservoir. <br /> <br />Turquoise Lake <br /> <br />At the end of Water Year 1970 (September 30), Turquoise Lake storage was <br />37,717 acre-feet. Of that amount, 15,513 acre-feet was owned by the CF&I Steel <br />Corporation; 7,391 acre-feet by the Homestake project; 2,087 acre-feet by the <br />High Line Canal Company; 2,779 acre-feet by the Pueblo Water Board; and 9,947 <br />acre-feet by the Fryingpan-Arkansas project. CF&I was storing a small amount <br />of Larkspur Ditch water for the Catlin Canal Company by exchange. <br /> <br />7 <br /> <br />
