Fontenelle

Fontenelle Reservoir is currently at elevation 6483.8 ft (54% full) and releases are approximately 950 cfs. The current rate of inflow is roughly 3,000 cubic feet per second (cfs) and will continue increasing with recent precipitation.

 Due to recent storm activity, the forecasted April-July inflow volume has increased substantially since early May, and it is anticipated that the official forecast issued in mid-May will be higher. Fontenelle shall be operated to accommodate the current increase in precipitation.

 Therefore, beginning Wedneday, May 11, 2016, at 8:00 a.m., releases from Fontenelle will be increased to 1,700 cfs according to the following schedule:

After the final change at 4:00 p.m. on Friday, May 13, 2016, releases will remain 1,700 cfs until further notice.   All times identified are local time (Mountain Standard Time) and not hour ending.

Releases will likely vary throughout May and June in response to observed hydrology. Due to the early spring runoff, it is anticipated that releases will be reduced beginning in July, and will likely reach baseflow levels in early August.  This is subject to change as additional information becomes available.
