Bureau of Reclamation releases flush dates!!

The bureau of rec has released the flush dates!

“The purpose of the fluctuations is to improve trout reproduction in the river,” said Wyoming Area Manager, Carlie Ronca. This spring, the Wyoming Game & Fish has requested flows for seven consecutive days. The Wyoming Game & Fish will collect data before, during, and after the flushing flow in order to evaluate its effectiveness.\

On March 18, flows in the river below Gray Reef Dam will fluctuate from 500 cubic feet per second (cfs) to 4000 cfs according to the following schedule:

HOURS                                               GRAY REEF OUTFLOWS (cfs)

00:01 to 01:00 a.m.                               500

01:00 to 02:00 a.m.                               2000

02:00 to 04:00 a.m.                               4000

04:00 to 04:30 a.m.                               3000

04:30 to 05:00 a.m.                               2000

05:00 to 06:00 a.m.                               1000

06:00 to midnight                                 500

This schedule will be repeated daily from March 18 through March 24. On March 24, the final day of the fluctuating flows, the peak flow of 4,000 cfs will be released for one additional hour and flows will ramp down to 500 cfs at 7:00 a.m. The schedule may be modified depending on river ice conditions.

The flushing flows are expected to clean the spawning gravels of fine sediment which has accumulated over the winter. The fluctuations in the river flow will be achieved without loss of power generation and the water released from Alcova Reservoir will be restored downstream in Glendo Reservoir.

The public is urged to use caution during this period of rapid fluctuation of flows below Gray Reef Dam.
