MILLS, Wyoming -- The Wyoming Area Office of the Bureau of Reclamation in Mills, Wyoming, will be lowering the water level in Guernsey Reservoir as the 2019 irrigation season draws to a close.

Guernsey Reservoir levels are expected to remain at the normal summer reservoir level through September 8. Reclamation will begin drawing down Guernsey Reservoir on the morning of Monday, September 9. It is anticipated that the reservoir will drop 12 feet to reach elevation 4400.00 feet by September 17. After September 17, the drawdown of Guernsey reservoir will vary based on timing and downstream demand. Users should be aware of declining water levels.

Glendo Reservoir levels are expected to continue gradually declining and reach a water surface elevation near 4597.30 feet (approximately 165,000 acre-feet) around September 30.

The planned reservoir elevations may change in response to changing water demands.

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