Radio telemetry data - Characterizing migration and survival for juvenile Snake River sockeye salmon between the upper Salmon River basin and Lower Granite Dam

Published by Northwest Fisheries Science Center | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 20, 2025 | Last Modified: 2017-02-08T00:00:00.000+00:00
This project estimates survival and characterizes the migration of juvenile sockeye salmon between the upper Salmon River basin in central Idaho and Lower Granite Dam on the Snake River in Washington state using multiple technologies. The approach will use PIT tags and radio telemetry to determine the magnitude, where, and when mortality occurs and characterizes the migration for Snake River sockeye salmon. The outcome of this study will directly contribute to actions that will play a significant part in recovery of ESA-listed Snake River sockeye salmon by examining key uncertainties and filling data gaps.
