Alright tons of good info and insights. I plan on doing some more fishing today (w/ nightcrawlers) to get pictures and sizes. The water is still cold here in Northern Ohio and very dark so I am not seeing a lot of fish right now.
The late spring/summer behavior of the bass was similar to rising trout right before the quick "hit and run action", they were in the open at the surface waiting for something. I really have never seen this behavior before, but I've never raised bass either. I do not know the DO content, but I plan on testing it. The pond is spring fed and the water is always moving down the drainage pipe, but it is possible the DO could be low especially in the summer.
The HBG vs BG identification is tricky so I will post pictures tonight or tomorrow of what I see.
