Guernsey Reservoir Silt Run

Media Contact: Coleman W. Smith, (307) 261-5671,

For Release: June 27, 2013

MILLS, Wyo. -- The Bureau of Reclamation's Wyoming Area Office will be lowering the water level in Guernsey Reservoir in preparation for the annual silt run. According to Coleman Smith, Wyoming Area Manager, the silt run is an operation which provides silt-laden water to Goshen, Gering-Fort Laramie, and Pathfinder Irrigation Districts under contract with Reclamation.

On July 7, 2013, the release of water from Glendo Reservoir will be decreased from approximately 4,000 cubic feet per second (cfs) to a flow of approximately 2,700 cfs. Smith said, "The decreased flow will cause a rapid decline of the Guernsey Reservoir level of approximately 15 feet during the period of July 8 through July 10." On Monday, July 8, the boat ramps on Guernsey Reservoir will no longer be usable due to the low reservoir level. From July 11 through July 24, water being released from Glendo Reservoir will flow through Guernsey Reservoir providing silt from Guernsey Reservoir into the canals of downstream irrigators. Beginning on July 24, the release of water from Glendo Reservoir will be rapidly increased to refill Guernsey Reservoir to a level suitable for recreation by the evening of July 26.

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