In August and September, the Stillaguamish Tribe spawned adult chinook collected on the North Fork of the Stillaguamish River. The tribe’s hatchery supplementation program has provided a comprehensive and long-running coded-wire tag harvest rate indicator data set.

Next spring, the tribal natural resources staff will release the offspring of these fish to ensure that the genetic integrity of the stock remains intact while not being vulnerable to extreme winter flow events.
