Thank you for the welcomes and replies. If I end up reworking the pond completely it would have to be a year from this fall. I have plenty of time to consider that option. Should I go ahead and cut down the trees on the dam this year? I could rather easily build the silt pond this year after a bit of research. Is there any harm to adding the muck eating bacteria either way? Also would using a trash pump on the bottom be a waste of time? I figured I could build the silt pond and run a pump around the bottom of the pond and basically take the water down to say half while trying to pump out much of the muck? What should I start googling to find the correct muck eating bacteria?

They are Black Crappie. I'll fish the pond more and see if I catch anything other than Bullheads.

I'll have to think about the best way to remove the Bullheads. Any thoughts on that would be great.
