Current Status

Last Updated: July 03, 2024

As of July 02, 2024, the Fontenelle Reservoir pool elevation is 6500.02 feet, which amounts to 86 percent of live storage capacity. Inflows for the month of June totaled approximately 257,129 acre-feet (af) or 84 percent of average.

After higher releases for June for spring runoff, release rates have ramped down to approximately 1,200 cfs and are expected to decrease to 1,100 cfs in mid-July. Releases may need to further decrease, pending hydrology.

The July final forecast for unregulated inflows into Fontenelle for the next three months projects much below average conditions. July, August, and September Most Probable inflow volumes amount to 77,000 af (45 percent of average), 40,000 af (61 percent of average), and 37,000 af (92 percent of average), respectively.
