Current Status

Average daily releases will likely remain at 1600 cfs through the end of May, or until the Larval Trigger Study Plan Razorback sucker spring peak releases are needed to supplement Yampa River peaks with a combined discharge of 18,600 cfs in Reach 2. This could mean a release of full power plant capacity and full by-pass, with a combined release of approximately 8,600 cfs.  The actual date of the dam releases is unknown currently and is dependent on the monitoring efforts from the United States Fish and Wildlife Service and Utah Division of Wildlife Resources.  The mean calendar date of the first capture of razorback sucker larvae (i.e., the "larval trigger") is May 28 (median May 27) and ranges from May 7 to June 24. Historically, 50% of first captures occurred between May 21 and June 2; 75% occurred between May 16 and June 4.  This is reiterated in the table below.

Table of when emergence has been observed in the past to be an indicator of when full power/by pass release will be invoked.

Description Range of dates of larval emergence
Date of first capture of razorback sucker larvae to start spring peak releases May 7 through June 24
50% first captures to start spring peak releases May 21 through June 2nd
75% first captures to start spring peak releases May 16 through June 4

The April final forecast for unregulated inflows into Flaming Gorge for the next three months projects near average conditions: May, June July forecasted unregulated inflow volumes at 235,000 af (96 percent of average), 360,000 af (92 percent of average), and 215,000 af (102 percent of average), respectively. 

As of May 10, 2019, Flaming Gorge Reservoir’s pool elevation is 6029.91 feet (88 percent of live capacity) and increasing. Inflow into Flaming Gorge Reservoir during the month of April was 197,774 af or 153 percent of average.
