Winter rearing habitat is a limiting factor for threatened coho salmon recovery in the Mid Klamath and other watersheds in the Klamath River basin. Overwinter survival of juvenile coho is approximately 2-6 times greater in off-channel habitats than within main channel habitats. This difference in survival rates is especially important in watersheds that have undergone significant changes due to land use. Working with the Karuk Tribe, US Fish and Wildlife Service, National Fish and Wildlife Foundation, and others, MKWC has constructed eight off-channel rearing habitats for juvenile coho between 2010 and 2013. These projects are being emulated in the Scott River, which has lost over 95% of its winter rearing habitat through channelization and beaver extirpation. We are collaborating with graduate students from Humboldt State University to quantify coho use and growth in these constructed habitats and to help us understand how to improve our restoration projects for maximum fisheries benefits.
