The Kokes will almost always run in the Thermocline. So if you have a boat with a finder... More power to you. Once you are within that temperature zone, it is a game to find what they will like in that particular hour. But generally speaking those little Kokanee will most likely be up higher within the cloumn, purely because the water is cooler at the surface than in the Summer, so I say look on the shallow side first. Although I have caught many many Kokes at GP when I did not mark any fish anywhere, and my gear was sunk looking for "lunker" trout. So like everything. Try all you have until you find your honey lure for the day.
