<br />Releases from cr.l are currently 650 cf4nd 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 are <br />expected to be in the 650 to 1,000 cfs range throughout the winter <br />months. During the Aspinall Operation meeting to be held April 19th <br />at 12:30 pm. in Grand Junction, Colorado, a plan for the spring and <br />summer release pattern will be developed. <br /> <br />NAVAJO - January inflow into Navajo were slightly below normal <br />(90 percent), and precipitation was well above average (130 <br />percent). The snowpack in the San Juan Basin is currently about 112 <br />percent of average. Since water year 1994 was a very close to a <br />normal year in the San Juan Basin, there are no lingering effects <br />and the spring runoff is expected to be above average ( 114 <br />percent) <br /> <br />Releases from Navajo are currently 500 cfs and are expected to <br />remain in this range throughout the winter months, as agreed at the <br />joint biOlogical/operations committees meeting. The releases from <br />Navajo during the spring and summer months will be set during an <br />operation committee meeting to be held in April. The exact date of <br />the meeting will be set in the next couple of weeks. <br /> <br />GLEN CANYON - Inflow was slightly below average during January <br />(93 percent) and precipitation was slightly above average at 102 <br />percent. CUrrently the snowpack in the Upper Colorado River Basin <br />is 92 percent of average and the most probable spring runoff for <br />1995 is expected to be 89 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 />
