flaming on
Utah/wyo closes the Flaming Gorge to Kokanee fishing I beleive Sept 1 st to protect the spawners. Yes the CPW does close east river to taking of kokes but encourages anglers to come catch/release during run, they have put articles in Denver post "best salmon fishing south of Alaska! well anybody that fishes kokes knows they dont catch and release well. Leave the fricking fish alone! But once again it is not biology it is tourism dollars

. once again different management techniques, if CPW was really concerned about those spawners they would close the river down for as long as they are running. I seen done in Alaska, it is called protecting the resource.

Chubby found this from 1990's timeframe
At one point the Utah chub was the Macks' primary food source. In the mid-1980s Brayton said there was a rapid decline in the chub population, which was about the time the lake trout numbers started to increase sharply. By the end of the 1980s, the chub had been eliminated from the lower two-thirds of the reservoir. They remain in the upper third only because the waters there are not as deep and warmer, two conditions lake trout don't favor.
With the elimination of the chub, the lake trout turned their attention toward kokanee and rainbow. Biologist noticed that about the time the chubs vanished, kokanee numbers suddenly stopped increasing
