<br />lHl3Hrl <br /> <br /> <br />-1991 Projections <br /> <br />Projections indicate that the C-BT <br />system will have almost 73.000 <br />acre-teet more In storage 10 beglO <br />1991 than 10 1990. While this IS <br />encouraging It IS by no means cause <br />for celebration among waler users <br /> <br />Projections for Lake Granby ShOw <br />that there will be approximately <br />35.000 more acre-feel of water In <br />storage at the beginning at the water <br />season In 1991 than In 1990. Lake <br />Granby should be 8-, 0 feet higher In <br />elevation on April 1. 1991 than the <br />prevIous April. The mid-summer <br /> <br />peak shaul be about' 0 feet above <br />the high waler elevation of 1990. <br /> <br />In addition, Carter Lake is expected <br />to be up 14.000 at and Horsetooth <br />ReservOir up 24,000 at from their <br />April 1990 storage capacIties. With <br />normal deliveries and average <br />preClpltallon throughout the season, <br />Horselooth and Carter should end <br />the 1991 water year at near normal- <br />juS1 below 50 percent full. <br /> <br />The carryover program contributed to <br />this Increase as more water was left <br /> <br />In the CoST system at the end of the <br />year. Relatively low C.ST water <br />deliveries along With average runoff <br />also contributed to the increase in <br />storage. <br /> <br />The follOWing graphs chart the <br />storage levels In the C-ST"s main <br />storage reservOirs dunng the 1990 <br />water delivery season, with projected <br />levels for 1991. The 1991 projections <br />are referred to as "most probable~ <br />meaning they are based on normal <br />delivery patterns and normal <br />preCIpitatIOn throughout the year. <br /> <br /> Lake Granby Horsetooth Reservoir Carter Lake <br /> Pt'fcen!
