Moose, In the spring ( now thru better part of may) the Lakers come inside the mountain out of NE in search of baitfish. Troll the inside of mountain ( 50ft +-) using techniques similar to deep water walleye. Larger spoons on Dipsys and downriggers. Hug the bottom. IF running downriggers keep the spoons close to the ball ( 5-10ft) Some guys even Bounce the ball off the mud to attract em.
My favorite spoon choice is silver NK28 w/green stripe. Silver /blue combo also work for us.

You wont catch many but when you do they are a blast. Had a 38 inch one mounted from the spring of 2006.
