I have pond (1.75 acres, 12' deep at the dam end) that was built 13 years ago and has been great fishing for many of those years. It is usually clear with a visibility of at least 2-3 feet. This year something has happened. The visibility is about 6" and has been that way since the last heavy run-off (about 5 weeks ago). It should have cleared up by now. I do not see any action on the surface. I haven't seen any beds from the spawn. I can't buy a bite from a bass or catfish---even the Bluegill bite is extremely slow. I used to have to hide behind a tree to bait my hook. Could it be that the pond has 'turned over'? I have never seen it do this before in the 13 years since I had it built. thanks
