Inflow into Fontenelle is about 1110 cfs and the elevation is about 6403.5 feet. Releases will likely remain near 1500 cfs through the middle of October. At this time, releases will be adjusted to a level that will likely stay in place throughout the the fall and winter period. The goal will be to maintain stable releases during the late fall and winter and also to draw down the reservoir to elevation 6463.5 feet by April 1, 1998 in anticipation of the 1998 runoff season. Due to above normal precipitation activity this past two months, inflows into Fontenelle have been above expected levels for the past two months, Because of this, releases from Fontenelle during August and September were higher than what they normally are. In August and September, inflow was 157 and 153 percent of normal, respectively. FLAMING GORGE - Releases from Flaming GQge are now steady at 2900 cfs with no hour to hour fluctuations. Releases were increased be to 2900 cfs on Friday October 3.

Currently, the reservoir has less than 4 feet of vacant space.
