For Release: March 06, 2012
The Wyoming Area Office of the Bureau of Reclamation in Mills, Wyo., has prepared snowmelt runoff forecasts for the North Platte River Basin, according to Lyle D. Myler, Acting Wyoming Area Manager. The March 1 forecast indicates the spring snowmelt runoff for the North Platte Basin will be below average.
Total April through July runoff in the North Platte Basin above Glendo Dam is expected to be 820,000 acre feet (af) or 85% of the 30 year average of 967,700 af. Approximately 550,000 af (71% of average) of the runoff is expected to enter Seminoe Reservoir with an additional 60,000 af (98% of average) being provided to Pathfinder Reservoir from the Sweetwater River, and the balance of 210,000 af (154% of average) coming from the basin between Pathfinder Reservoir and Glendo Reservoir.
The total storage for the North Platte Reservoir System as of February 29, 2012, is 2,242,778 af, which is 139% of the 30-year average of 1,618,900 af. The total conservation storage capacity of the North Platte Reservoir System is approximately 2,841,000 af.
Due to above average forecasted inflow between Pathfinder and Glendo Reservoirs and the above average Glendo Reservoir Storage (118% of the 30 year average), releases from Guernsey Reservoir are anticipated to be initiated in early April this year.
Reclamation will update the inflow forecasts again in April, and May.
