<br />Pumping to Carter Lake from Flatiron Reservoir started December 10, and continued through <br />December 15. Pumping was shut down for the remainder of December because of the need to <br />complete the Bifurication (By-Pass) Project at Flatiron, a by-pass pipe that could be used if <br />Flatiron #3 PumpfGenerator should ever fail to pump water to Carter Lake. Pumping resumed <br />on February 10, and continued until May 27, when Carter Lake's capacity had reached 109,371 <br />acre-feet. Through part of June, an additional 7,488 acre-feet was pumped to Carter Lake filling <br />it up to a capacity of 111,464 acre-feet at a water surface elevation of 5,758.33 feet. Pumping <br />during July added 8,902 acre-feet, while 3 more days of pumping during August added another <br />632 acre-feet. <br /> <br />The maximum storage for the water year was reached on June 29; 111,464 acre-feet on at water <br />surface elevation 5758.33 feet. <br /> <br />Deliveries to the St.Vrain Supply Canal began in early April and were unusually high, with a <br />total for the month of 5,233 acre-feet, including metered delivery. Water deliveries for May <br />decreased to a total of2,175 acre-feet, and were well below average for June at 2,100 acre-feet. <br /> <br />Project water deliveries continued well below average in July at 8,785 acre-feet. Project water <br />deliveries totaled 11,272 acre-feet in August and 9,220 acre-feet in September. The storage at <br />the end of water year was 74,231 acre-feet, 19,791 acre-feet above the 30-year average. <br /> <br />Water year deliveries to the St. Vrain Supply Canal totaled 53,686 acre-feet, well below the 30- <br />year average of 67,510 acre-feet. <br /> <br />Flatiron Unit 3 generation occurred during the months of August and September. Unit 3 used a <br />total of 15,485 acre-feet for power generation during water year 1999. <br /> <br />A total of 84,800 acre-feet of water were pumped into Carter Lake during the water year 1999, <br />which was 109 percent of the 30-year average. This activity required a total of <br />28,600,000 kilowatt-hours of energy. <br /> <br />Horsetooth Reservoir <br /> <br />Completed in 1949, with four dams, Horsetooth Reservoir has a total constructed capacity of <br />156,700 acre-feet. Inflow of Project water is from Flatiron Reservoir via the Charles Hansen <br />Feeder Canal. <br /> <br />Horsetooth Reservoir storage of81,947 acre-feet at the start of water year 1999 was 3,137 acre- <br />feet above the 1966-1995 average of 78,810 acre-feet. <br /> <br />During October, project water brought through the Adams Tunnel from Lake Granby to <br />Horsetooth Reservoir was severely restricted due to ongoing canal maintenance and Catagory-l <br /> <br />15 <br />
