The Hood Canal Steelhead Project is a 17-year before-after-control-impact experiment that tests the effects of supplementation on natural steelhead populations in Hood Canal. There are three supplemented and four control (non-supplemented) populations that are being monitored for adult and juvenile abundance, life history, and genetic diversity. The project also quantifies early marine survival and behavior and ecological interactions between hatchery- and natural-origin steelhead. Project data, parr and smolt data set from 2007-2015.
