As of December 2, 2020, the Fontenelle Reservoir pool elevation is 6487.64 feet, which amounts to 61 percent of live storage capacity. Inflows for the month of November totaled 32,400 acre-feet (af) or 77 percent of average.

Fontenelle’s releases are currently set at 825 cfs. This release is scheduled to be maintained through the Fall/Winter operation period, which typically ends in March when ice on the Green River begins to thaw.

The December final forecast for unregulated inflows into Fontenelle for the next three months projects below average conditions. December, January, and February inflow volumes amount to 27,000 af (84 percent of average), 26,000 af (86 percent of average), and 24,000 af (87 percent of average), respectively. 

The 2021 water year unregulated inflow volume is forecasted to be 799,000 af (74 percent of average).  This is a decrease when compared to the November forecast when the unregulated inflow volume was forecasted to be 837,000 af (77 percent of average).
