For Release: September 14, 2016
MILLS, Wyo. -- The Bureau of Reclamation will be lowering the water level in Guernsey Reservoir as the 2016 irrigation season draws to a close.
Guernsey Reservoir levels are expected to remain accessible for boating recreation through September 18. Reclamation will begin drawing down Guernsey Reservoir on the evening of Sunday, September 18, and the boat ramps will quickly become unusable. Reclamation advises that watercraft be removed from the reservoir by the evening of Sunday, September 18.
Guernsey Reservoir releases are expected to gradually decrease beginning on September 14 with the end of major irrigation demands. On the afternoon of September 16, releases from Guernsey Reservoir will be set to approximately 2,000 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 4589.5 feet (approximately 140,000 acre-feet) around September 19. Glendo releases will be discontinued for the winter by September 25 and Glendo Reservoir levels will then stabilize and slowly increase after October 1.
Boaters, recreationists, and irrigators should take proper precautions regarding changing river flows between Glendo and Guernsey Reservoirs and the lowering of Guernsey Reservoir.
