For 2019, the project is planned to incorporate knowledge gained during 2018 to achieve the goal of obtaining a comprehensive understanding of Chinook spawning distribution in the upper portion of the Teslin River watershed. This will be accomplished through the following: increasing the number of tags to be applied, focusing the tag application on the early portion of the run, and increase the crew size to four individuals to allow for tag application to be completed 24 hours a day. Understanding of the extent and relative importance of tributaries used for spawning will guide monitoring efforts and future restoration activities to places where they are appropriate and will have the greatest potential for contributing to the restoration of Chinook salmon stocks. The new radio telemetry data will be combined with the existing data to strengthen the knowledge of Chinook spawning distributions and will make the data more relevant by applying tags throughout the run.
