Aspinall Unit Reservoirs – As of January 13, 2020 releases from Crystal Dam are approximately 1,100 cfs. Gunnison Tunnel diversions are occurring about every 2 weeks to refill Fairview Reservoir. Flows in the Black Canyon are about 1,060 cfs. Releases from Crystal are projected to remain at about this level until the end of January 2020 when releases likely will be decreased.
Blue Mesa did fill in 2019 and achieved a peak elevation on July 25, 2019 of 7519.15 feet above sea level which corresponded to a storage content of 827,000 af (99 percent of full pool). Since this peak filling, Blue Mesa's elevation has declined to 7488.71 feet above sea level on January 13, 2020 and this trend will continue until about the beginning of April 2020.
The unregulated inflow volume in December to Blue Mesa was 29.0 kaf (108 percent of average). Unregulated Inflow volumes forecasted for Blue Mesa for the next three months (January, February, March) are projected to be: 25,000 af (104 percent of average), 23,000 af (104 percent of average) and 37,000 af (103 percent of average), respectively. The January 24-Month Study is reflective of these new forecasts. The water year unregulated inflow forecast volume for 2020 is 0.851 maf which is 89 percent of average.
