Fontenelle Dam

Current Status

Last Updated: October 2, 2020

As of October 1, 2020, the Fontenelle Reservoir pool elevation is 6494.43 feet, which amounts to 75 percent of live storage capacity. Inflows for the month of September totaled 25,000 acre-feet (af) or 55 percent of average. .

Releases were lowered on September 21st to 900 cfs to compensate for lower inflows and pool elevation. Due to scheduled maintenance releases have been switched from power generation to bypass until mid-October.   

The October final forecast for unregulated inflows into Fontenelle for the next three months projects below average conditions. October, November, and December inflow volumes amount to 33,000 af (68 percent of average), 35,000 af (83 percent of average), and 30,000 af (94 percent of average), respectively. 

The final total water supply of the April through July inflow volume into the Fontenelle Reservoir is 677,000 acre-feet (93 percent of average).
