<br />ABPIDLL - Febru. inflow was above avera. (118 percent) The <br />precipitation during February was above average (138 percent). The <br />snowpack in the Gunnison basin is currently about 133 percent of <br />average. This all adds.up to a slightly above average runoff that <br />is expected this year ( about 106 percent of average). <br /> <br />Releases from Crystal are currently 650 cfs and there are no <br />diversions through the Gunnison tunnel. The storage at Blue Mesa <br />at the end of December was 579,300 at elevation 7489.77. This was <br />0.23 feet under the target elevation of 7490. Releases will be <br />increased from 650 to 1,300 cfs range during March. The releases <br />will also be increased to 1900 cfs in April. During the Aspinall <br />Operation meeting to be held April 19th at 12:30 pm. in Grand <br />Junction, Colorado, a pIan for the spring and summer release <br />pattern will be developed. <br /> <br />IIAVAJO February inflow into Navajo were above norma 1 <br />(209 percent), and precipitation was about average (99 percent). <br />The snowpack in the San Juan Basin is currently about 126 percent <br />of average. Since water year 1994 was)( very close to a normal year <br />in the San Juan Basin, there are no lingering effects and the <br />spring runoff is expected to be above average ( 121 percent). <br /> <br />Releases from Navajo will be increased from 500 to 2000 cfs in <br />March. The releases from Navajo during the spring and summer <br />months will be set during an operation committee meeting to be held <br />March 14, 1995. <br /> <br />GLBB caBYOK - Inflow was slightly below average during February <br />(96 percent) and precipitation was slightly above average at 119 <br />percent. CUrrently the snowpack in the Upper Colorado River Basin <br />is 110 percent of average and the most probable spring runoff for <br />1995 is expected to be 96 percent of average. <br /> <br />Lake Powell lost 1,018,000 acre-feet of storage this last year. <br />Additionally, no equalization releases would be required in water <br />year 1995 under the most probable inflow condition. <br /> <br />Releases from Glen Canyon will continue to be made under the <br />interim flow restrictions. <br />
