As a part of the Northwest Power Planning Council`s Fish and Wildlife Program, the Fish Passage Center collects information on the migrational characteristics of juvenile salmon and steelhead (Oncorhynchus sp.) in the Columbia River basin. This information is collected through the Smolt Monitoring Program, and is used as a tool in the management and evaluation of the Water Budget. The Water Budget is a volume of water used to enhance environmental conditions (flows) to aid in the seaward migration of juvenile salmon and steelhead. Implicit in the Water Budget concept is that by augmenting flows, travel time of juvenile salmonids will be decreased, thereby increasing survival via reductions in delayed migration and exposure to predators. This study was initiated to (1) provide physiological information about the juvenile salmonids used for these travel time estimates, (2) to analyze the physiological data, and (3) to determine if an ``index`` of smolt condition could be developed to aid in management of the Water Budget.
