TrickyFish is correct on the history of Kokes in East. The problem was with the fertilizer runoff from upstream golf courses/Jeremy Ranch area. These nitrates settle to the lower depths of the lake and displace the oxygen in the water. This limited the Kokanee's ability to follow the thermocline to deeper depths in the summer months. (They will go down to depths of 40-70 feet in these smaller lakes.) This kept the fish in warmer waters, where they don't survive well at all.There is a very small naturally reproducing population in there currently. So hopefully the augmentation will allow the fish to rebound. I do not know if the pollutants have been reduced in the creek, but I sure hope they have. If not, the problem will persist, and the salmon will essentially die out again.
Incidentally this is the same reason the trout can suffer from the anchor worms up there. The worms do not do well if the trout can get to cooler/deeper waters.
