Here's some of my fishing results from the past two seasons. Most Thursdays you'll find me at the lake sitting under a bridge with my boat tied to the bridge pier. We fish at around 30 ft depth. and use medium minnows.
I mostly fish for crappie at Smithville Lake, which must be 9" or longer in MO. Occasionally we also catch channel cat, walleye pike, drum, striped bass, large mouth bass and perch, all by using medium sized minnows. I've had some luck, too, with various colored plastic minnows when we run out of live ones.
