I'm pretty sure they catch some kokanee at the Fishing Bridge on the east end of Riffe. I know there are landlocked coho plus rainbows, but I believe there are some kokanee as well.

At Rimrock, people catch kokanee from shore, working steep banks. When I fished there, the folks were chumming (don't know if it's still legal) to draw them in. I've caught kokanee from the shore at Cushman as well.

In the spring try fishing the mouths of creeks or rivers where they dump into the lake.
