Interesting. I just got done checking out the "Puget Sound River Sockeye" page. ( http://wdfw.wa.gov/fish/sockeye/riverpuget.htm )I always thought that a lake was needed to rear the juveniles. I wonder if you could use Lake Tapps for juvenile sockeye rearing. The fish could spawn, rear in the lake and then go to sea after a few years. Would they need to re-enter the lake on the way back to the spawning grounds or could they bypass that and just continue up the White?
