Current Status

Last Updated: May 19, 2020

As of May 18, 2020, the Fontenelle Reservoir pool elevation is 6483.97 feet, which amounts to 55 percent of live storage capacity. Inflows for the month of April totaled 83,000 acre-feet (af) or 97 percent of average.

As we continue Spring operations at Fontenelle we are anticipating inflows to continue increasing in May. Consequently, releases will increase from 1,700 cfs to 1,780 cfs on May 21st.

The May final forecast for unregulated inflows into Fontenelle for the next three months projects below average conditions.  May, June, and July inflow volumes amount to 175,000 af (107 percent of average), 265,000 af (89 percent of average), and 147,000 af (83 percent of average), respectively. 

The May water supply forecast of the April through July inflow volume into the Fontenelle Reservoir is 670,000 acre-feet (92 percent of average). Current snowpack is 72 percent of median for the Upper Green Basin.
