<br />FONTENELLE - Currently the elevation of Fontenelle is approximately 6498 feet above sea level which is
<br />8 feet below maximum capacity, Releases are being decreased from 7500 cfs to 4500 cfs during the. week of
<br />July 5th to July 12th in order to increase the reservoir elevation,
<br />
<br />The forecast, issued July 1st, has Fontenelle inflows set at 225,000 acre-feet during the month of July. May
<br />and June both saw inflows which were greater I.han forecasted values. The forecasted inflows for June were
<br />500,000 acre-feet while the total recorder! inflow turned out to be about 568,000 acre-feet.
<br />
<br />Releases from Fontenelle will mOSl likely decrease over the next several weeks as inflows decrease to base
<br />levels. However, if inflows pick up during the month, it may become necessary to increase releases in order
<br />to prevent an uncontrolled spilL Fontenelle will be very nearly full by mid July,
<br />
<br />FlAMING GORGE - Releases from Flaming Gorge Reservoir are now at powerplant capacity of 4500 cfs.
<br />With inflow finally slowing down, a reduction in releases has now been scheduled. Releases will be
<br />reduced according to the following schedule.
