My suggestion would be to close the lake to kokanee fishing in order to maintain the largest amount of spawners possible. Should be able to fish for trout as you would not catch to many kokanee that way. Release all Kokannee. No directed catch and release on Kokanee. After 5 years if no Sockeye, then do it how ever........Planting chambers creek stock........I'm sorry but you have to be kidding me, give the native rainbows in the upper river a chance if there are any.......anyone know whats up river at the moment?
