Buddy sent me this rather interesting link that shows quite graphically the migration pattern of adult sockeye and chinook tagged in Lower Cook Inlet.
Feel free to play around with the settings and the zoom to get a detailed look at these migration patterns.
Watch how one sockeye travels all the way Cook Inlet to the mouth of the Kenai before deciding it's lost, then backs out of the inlet, and finally finds its way to Kodiak Island.
One Kenai king swims 34 laps back and forth in front of the Kenai mouth for 17 days before finally committing to the river.
One exceptional king travelled south for 16 days all the way down to Tongue Point in the Columbia River estuary.
