Back in the late 1800s when the runs were first over harvested and the hatcheries were built to sustain the runs they used the Tules strain kings which are from the Kalama River.The eggs from these fish were used for many years to build runs in the water sheds through out Wash. State,these fish returned early to the Kalama watershed but as you know they return in the fall to the rivers you are now fishing which is why you can catch boots out in Elliott Bay.
