I drive past there on the way to Jim Edgar Panther Creek State Park, but have never fished there. It would be nice to know if they have a good population of Cats in that lake, always looking for new places too fish. If JEPC isn't too far for you too drive, Prairie lake has some nice cats in it.
I think the limit is 10hp at any speed, and larger motors can run at idle speed. I took my pontoon boat with 60hp and putting around with it at idle was all I needed to do anyway. There's lots of structure all around the lake that makes for good fishing. Also, 6 catfish limit per day.
