MILLS, Wyoming -- The Bureau of Reclamation, in response to a request from the Wyoming Game and Fish Department, has re-scheduled a series of fluctuating flows in the North Platte River downstream of Gray Reef Dam. Fluctuating flows were previously scheduled to begin on March 18. This operation has been postponed to accommodate construction work at the Alcova Bridge. The new start date for the fluctuating flows is Friday, March 29.
The purpose of the fluctuations is to improve trout reproduction in the river. This spring, the Wyoming Game & Fish has requested flows for ten consecutive days.
On March 29, 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 03:00 a.m.||2000|
|03:00 to 07:00 a.m.||4000|
|07:00 to 08:00 a.m.||3000|
|08:00 to 09:00 a.m.||2000|
|09:00 to 10:00 a.m.||1000|
|10:00 to midnight||500|
This schedule will be repeated daily through April 7. After completing the flushing flow on April 7, 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.
