Basin. The operating plans are updated monthly to reflect changing inflow conditions. This
report focuses on the information associated with the April expected operating plan.
Table 1 also includes the accompanying information for water year 2008 and the 30 -year average
(1979 -2008) for comparison. Graph 1 through Graph 3 displays this information in graphical
format. Based on the April expected North Platte River Operating Plan, the North Platte
Pathfinder ownership (refer to NPRAOP page 3) is estimated to reach a fill by the end of May.
The North Platte Guernsey ownership is also expected to fill by the end of May.
Assuming the Pathfinder Modification Project was in operation and the North Platte Pathfinder
ownership filled, the Pathfinder Environmental and the Wyoming Accounts would also be
expected to fill.
The Glendo and Kendrick ownerships would not fill given expected inflow and outflow
conditions. The Kendrick ownership is expected to come into priority for accrual in 2009, but
not fill. However, Glendo ownership is not expected to come into priority for accrual in 2009.
For the Glendo Ownership this is due to the anticipation of May releases from Guernsey
Reservoir for irrigation, which will draw the lower reach gains through for delivery. The amount
of accrual to the Kendrick ownership is dependent on when Pathfinder fills and the inflow
conditions. Releases from Guernsey Reservoir are expected to be in response to downstream
demand.
Reclamation will continue to update the North Platte River operating plans on a monthly basis in
response to changing inflow conditions. Reclamation will prepare the determination of
forecasted supply estimate again on May 1 and June 1 with regard to the need to allocate storage.
