Im brand new here, but have learned alot from the experts
on this site. A few things I can repeat from them. First more info is need about your pond, your location etc.
second, it sounds like you need to do some earth working. If your ponds "dirty" maybe you have excess run off? Or fish that are working up the muddy bottom.
Then thier are questions about what your managment goals are. Bass, panfish, and the size and number of each. I don't have the answers but ive seen lots of questions.
