Fontenelle Dam

Current Status

Last Updated: August 5, 2020

As of August 4, 2020, the Fontenelle Reservoir pool elevation is 6503.86 feet, which amounts to 95 percent of live storage capacity. Inflows for the month of July totaled 145,000 acre-feet (af) or 82 percent of average.

As the forecast continues to show inflows into Fontenelle dropping through the Summer we anticipate lowering relases. Consequently, releases were decreased beginning on July 22nd and ending on July 23th from 1,700 cfs to 1,300 cfs.

The August final forecast for unregulated inflows into Fontenelle for the next three months projects below average conditions.  August, September, and October inflow volumes amount to 60,000 af (78 percent of average), 40,000 af (87 percent of average), and 45,000 af (93 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).
