For Release: September 10, 2015

MILLS, Wyo. -- The Wyoming Area Office of the Bureau of Reclamation in Mills, Wyo., will be lowering the water level in Guernsey Reservoir as the 2015 irrigation season draws to a close, according to Carlie Ronca, Wyoming Area Manager.

"Guernsey Reservoir levels are expected to remain accessible for boating recreation through September 13," Ronca said. Reclamation will begin drawing down Guernsey Reservoir on the evening of Sunday, September 13, and the boat ramps will quickly become unusable. To avoid potential problems associated with declining reservoir levels, Reclamation advises that watercraft be removed from the reservoir by the evening of Sunday, September 13.

Guernsey Reservoir releases are expected to gradually decrease beginning September 13 through September 16, with the end of major irrigation demands. The morning of September 16, releases from Guernsey Reservoir will be set to approximately 1,700 cfs until the end of September when they will be discontinued for the winter.

Glendo Reservoir levels are expected to continue gradually declining and reach a water surface elevation near 4589 feet (approximately 123,000 acre-feet) around September 17, after which the reservoir levels are expected to slowly increase.

Boaters, recreationists, and irrigators should take proper precautions regarding changing river flows between Glendo and Guernsey Reservoirs and the lowering of Guernsey Reservoir.
