If you would strickly target pike and walleye you would probably get a couple. Minne is typically a crappie lake tho. And if you don't have a flasher...I wouldn't bother. If you do, try deep 25'+. You will find the deeper water just off the boat launch. For the most part you should be able to drive all over the lake with a 4x4. The two areas you mentioned (dam, and southeast corner) are primarily walleye and pike spots. Try there with typical walleye presentations (jig and minnow) or tip-ups with dead bait for pike, and you should get a couple bites. But if you don't have electronics or light tackle you are in for a disapointment if you want to catch a couple crappies.
