Hello:

Fontenelle Reservoir is currently at elevation 6500.4 ft (87% full). The rate of inflow is roughly 980 cubic feet per second (cfs), with recent daily averages ranging from 900 cfs to 1,020 cfs. Weather conditions are expected to continue to be relatively cool and dry, though strong storms continue to track southeast of the basin. The Colorado Basin River Forecast Center has forecasted late summer reservoir inflows that are below average. Fontenelle will be operated to accommodate the anticipated hydrologic conditions.

Beginning Monday, August 17th, 2015, at 8:00 a.m., releases from Fontenelle will be decreased to 1,200 cfs according to the following schedule:

After the final change at 4:00 p.m. on Monday, August 17th, 2015, releases will remain at 1,200 cfs until further notice. All times identified in this notification are local time (Mountain Standard Time) and not hour ending.
It is anticipated that releases will be further reduced to a baseflow near 1,000 cfs at the end of August. This is subject to change based on observed hydrology.

Note that technical issues will prevent the Reclamation website for Fontenelle from being updated with the latest information for the foreseeable future. As a reminder, the next Fontenelle Working Group meeting is scheduled for August 26, 2015, at 10:00 am. Please note that the meeting location has changed. The meeting will now be held at the Wyoming Game and Fish Department, 351 W. Astle Avenue, Green River, WY 82935. The Fontenelle Working Group is an open public forum for information exchange between Reclamation and other parties associated with the operation of Fontenelle Reservoir.

If you have any questions or concerns, please call me at (801) 524-3716. Your cooperation is greatly appreciated.
