Spring Flush schedule is released for March 13th through March 21
On March 12, flows in the river below Gray Reef Dam will fluctuate from 500 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 03:00 a.m. 2,000 03:00 to 07:00 a.m. 4,000 07:00 to 08:00 a.m. 3,000 08:00 to 09:00 a.m. 2,000 09:00 to 10:00 a.m. 1,000 10:00 to midnight 500
This schedule will be repeated daily on March 13 through March 21. After completing the flushing flow on March 21, the flows below Gray Reef Dam will return to 500 cfs. 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.
