The Wyoming Area Office of the Bureau of Reclamation in Mills, Wyoming, has prepared snowmelt runoff forecasts for the North Platte River Basin, according to John H. Lawson, Wyoming Area Manager. The March 1 forecast of the spring snowmelt runoff indicates below average April through July snowmelt runoff can be expected at all forecast locations within the North Platte Basin in Wyoming except the inflow to Seminoe Reservoir, which is average.

Total April through July runoff in the North Platte Basin above Glendo Dam is expected to be 810,000 acre feet (AF) (91 percent of average) compared to a 30-year average of 886,400 AF. Approximately 700,000 AF (99 percent of average) of the runoff is expected to enter Seminoe Reservoir with an additional 25,000 AF (41 percent of average) being provided to Pathfinder Reservoir from the Sweetwater River, and the balance of 85,000 AF (70 percent of average) coming from the basin between Pathfinder Reservoir and Glendo Reservoir.

The water in storage for delivery to North Platte Project contractors is 763,386 AF (133 percent of average). Since the March 1 forecast is below average, Reclamation continues to encourage water conservation in planning for the upcoming season. Reclamation will update the inflow forecasts again in April and May.
