Greetings
The Fish and Wildlife Service (FWS) has identified larval razorback suckers in Reach 2 of the Green River. With the presence of larval razorback suckers, FWS has requested the implementation of the Larval Trigger Study Plan (LTSP) releases as identified in the Flaming Gorge Operational Plan May 2024 - April 2025.
Beginning on May 22, 2024, the daily average release from Flaming Gorge Dam shall increase following the schedule below:
NOTE: Bypass will be used at Flaming Gorge Dam to achieve releases greater than ~4,600 cfs in the table above. The hourly release schedule above is an approximation of releases. All data is provisional and is subject to change.
The daily average release of 6,600 cfs will continue thereafter or until a new notification is issued.
Recreationists on the Green River should take caution and be aware the increased flows in the river will be cold and swift. The Flaming Gorge Dam releases for the LTSP are currently planned to stay at ~6,600 cfs through the weekend and Memorial Day, pending hydrology. If any changes are needed to the schedule above, then changes will be implemented before COB Thursday (5/23).
This data is considered the most likely scenario given the current forecast and is subject to changing conditions. Forecasted (tentative) hourly release schedules can be found by visiting the Colorado River Basin Forecast Center (CBRFC) at this website:
https://www.cbrfc.noaa.gov/dbdata/station/flowgraph/flowgraph_hc.html?id=GRZU1&ptype=3&linear_flow=0.
Please note that the CBRFC data is in Zulu time, which is 6 hours later than MDT. For example, 6 pm Zulu (Z) is 12 pm MDT.
Notifications such as this one could take some time, a day or so, to be reflected on the website.
Thank you,
