Are there Blue catfish and Flathead in the lake? Or only Channel cats?

Not sure about catfish

4 to 5 pound cat fish. 1.5 to 3 lbs in bass, rather small crappie. Most bites are not offten. Dangerous waters in boating, many high tree stumps just under a foot, plus high and low spots. Watch fish finder for most high areas , you can get stuck.

In my experience, we have only caught channel cats at Maple Leaf.

What lake
