Another dry year on the Green. <br /> <br />ASPINALL UNIT - Blue Mesa is still wide open at 1400 cfs. The first <br />of the uprating is expected back this month and will have a higher <br />release capability. The forecast increase was accommodated by an <br />increase in maximum storage--there is still 100,000 AF of release <br />capability in the spring months before be have to bypass Blue Mesa. <br /> <br />NAVAJO - Releases still 600 cfs. Snow pack is the highest of the <br />basin, slightly above normal, and the reservoir is expected to peak <br />out higher than we expected this year. <br /> <br />GLEN CANYON - 700,000 AF increase in April-July-volume over January 1 <br />forecast. This allowed higher late-winter releases and brought <br />June-July releases back to what we feel is an optimal level. <br /> <br />Several of the turbines have had seal ring problems lately (failure <br />and cracking). 3 of the 8 units were down for a time in January and <br />the Bureau is investigating the nature and cause of the problem. <br /> <br />The beloved Glen Canyon Environmental Studies have been sent to the <br />
