I fish this lake all the time. Only method to use is trolling. You can pretty much troll this lake anywhere and nail fish. I usually use 2.5 colors of lead line w/ 5 bladed flasher and a wedding ring tipped with worm or marshmellow (depends if girlfriend forgets the worms)
Typical trout are small, however if everyone in the boat doesn't limit out within 1-2 hours your doing something wrong.
We did land 1 9 lb cuthroat monster, my little girlfriend had a heck of a time reeling that one in earlier this year.
Also the trout are nice and pink, Probaboly the best eating in eastern washington short of roosevelt.
