Deer Creek Drawdown Zone Fish Habitat Enhancement: A Pilot Study (Phase II) for Lower Arrow Lakes Tributary Access Improvements
Author: E. Smith, M. Zimmer
The two main goals of Phase II (2016) were: Goal 1: Add in-stream cover and increase water depth from the end of Phase I works downstream 100 m to an old bridge cribbing. Objective 1 Create stable wood and rock structures that will provide cover for migrating Kokanee and other inhabiting fish, and Objective 2 Create a defined single channel to increase water depth and reduce the potential for channel braiding. Goal 2: Monitor the effectiveness of enhancement structures implemented in Phase II Objective 1 Develop a map of pre and post-enhancement conditions, Objective 2 Conduct post-freshet and post reservoir infilling, georeferenced stability assessment of structures in 2017, and Objective 3 Observe Kokanee use in the treated section (Phases I and II).
installation of fish habitat structures (large woody debris); several hundred Kokanee were observed in the Phase II section of the drawdown zone in September 2016, whereas no Kokanee were observed in the stretch below the last structure (Structure 19) to the reservoir. Kokanee were also observed spawning under structures on September 10 2016.
