Fontenelle Reservoir is currently at elevation 6500 ft (87% full) and releases are approximately 1,100 cfs. Releases will decrease to 1,000 cfs on August 17, 2016 and are anticipated to decreased to base flow levels of approximately 960 cfs sometime in September, subject to hydrology. The July final forecast decreased from the June midmonth volume of 710,000 acre-feet (98 percent of average) to 650,000 acre-feet (90 percent of average). Fontenelle will be operated to accommodate the decreasing forecast volume. Releases are anticipated to remain at this level through July and then decrease.
Inflows for the month of July totaled 80,000 acre-feet (af), or 45 percent of average. The Colorado Basin River Forecast Center has forecasted spring inflows that are much below average. August, September and October forecasted inflow volumes amount to 44,000 af (58 percent of average), 36,000 af (78 percent of average), and 40,000 af (82 percent of average), respectively.
