MILLS, Wyo. -- The Bureau of Reclamation expects above average flows on the North Platte River System for the remainder of June, decreasing to average flows later in the summer. "We will have average to higher than average reservoir levels due to above average carryover storage in the reservoirs and slightly above average inflows," said Wyoming Area Manager, Carlie Ronca.

Spillways are presently in operation at Kortes and Alcova Dams, and other spillways and outlet works along the North Platte River will be operated as necessary to manage reservoir levels. The public should be aware of the changing river flows and reservoir levels and take proper precautions.

The release from Seminoe Dam through the Miracle Mile has been increased to approximately 4,500 cfs (cubic feet per second) but is expected to decrease by the end of June. The current release below Pathfinder Dam is approximately 4,300 cfs and, at this time, the reservoir is not expected to spill. The current release from Gray Reef Dam is approximately 4,000 cfs and is expected to vary according to downstream irrigation demands for the remainder of the summer.

Glendo Reservoir is about 1 foot below the top of the active conservation pool and is rising slightly. At this time, the reservoir is not expected to enter into the exclusive flood control pool. The Guernsey Reservoir releases of 4,100 cfs are being made to manage reservoir levels in the system and satisfy downstream irrigation demands. That outflow is projected to continue through the month of June with an increase to 5,200 cfs by early July in response to downstream demands.
