As of June 7, 2021, the Fontenelle Reservoir pool elevation is 6483.38 feet, which amounts to 53 percent of live storage capacity. Inflows for the month of May totaled 76,000 acre-feet (af) or 47 percent of average.
Due to dry hydrologic conditions in the Upper Green River Basin, Fontenelle’s releases were lowered from 825 cfs to 700 cfs on May 24, 2021. Based on the latest observed inflows and June forecast for the period between April and July, this year’s inflows into Fontenelle Dam are projected to be the 7th driest since 1966.
The June final forecast for unregulated inflows into Fontenelle for the next three months projects dry conditions. June, July, and August inflow volumes amount to 150,000 af (50 percent of average), 65,000 af (37 percent of average), and 35,000 af (46 percent of average), respectively.
