Objectlve: Calibrate the While River Basin Phase ill model network. It is expected that the
qUalit~ of the calibration of the Phase III model will decrease relative to the Phase IT calibration
(more iletail does not mean better calibration). However, it is expected that the ealibratiou of the
I
Phase III model can be made to achieve a level that is within 20 percent of the Phase IT effort.
