Evaluate Steelhead (Oncorhynchus mykiss) Kelt Outmigration from Lower Granite Dam to Bonneville Dam and Test the Use of Transportation to Increase Returns of Repeat Spawners

Abstract

A field study was conducted at Lower Granite Dam, Washington; in the spring of 2002 to identify and enumerate kelt steelhead collected in the juvenile bypass system and evaluate their age-structure, and genetic profiles. We also investigated kelt steelhead migration rates, routes, and survival as well as compared return rates of transported verse in-river migration strategies.
