Morley River Chinook Stock Restoration Planning

This project involves a combination of field assessments and office-based tasks to set the stage for Chinook stock restoration on the Morley River, a tributary of Teslin Lake in the upper portion of the Teslin River watershed. Morley River is well known as a Chinook spawning stream and the stream continues to be used for spawning currently. The Deadman Creek Chinook stock restoration project has collected a considerable amount of information on Chinook spawning in Morley as this stream has served as a source of brood stock and a control stream for egg planting methods being used in Deadman Creek. From 2016 to 2018 (2019 in progress), both egg hatching and emergence success were high and provided strong confidence in the quality of the incubation conditions in Morley River, particularly the portion directly downstream of Morley Lake where this work has focused. The portion of the Morley River where this work was undertaken is located 1-2 km downstream of Morley Lake and therefore has very little fine sediment present and the stream remains open during the winter months due to the outflow of relatively warm water from the lake. Despite these highly suitable conditions for spawning, spawner returns to the watershed are far below historic levels based upon local/traditional knowledge and historical aerial survey data. Considering this collective information and the accessibility of the watershed, Morley River is an ideal location to conduct a stock restoration initiative. The current project is proposed to complete a watershed specific restoration plan for Morley River Chinook and to collect field data to inform the preparation of this plan.
