Welcome Colin, unfortunately I don't know anything about that lake either. But with the heat of summer, unless its first thing in the morning or around sunset I doubt they are bass feeding that you are seeing. Most likely panfish, see them all the time at Black Hills right at the surface in 40 feet of water. For the bass, try to find spots that have a drop off to deeper water, a dropoff with structure is perfect.
I haven't heard anything about snakehead from there, if it is any moving bait will work. Spinnerbaits, and chatterbaits work. They are rather aggressive feeders.
Nice bass BMBass, spinnerbaits is one of the techniques I need to get better at. I am more of a finesse person, I know what will surprise Basser89.....
