Hello - I am new to this site. I do not know yet how to post a question, but it is very similar to this one. My pond is about 1/4 acre with the deepest being 5 feet. It is nothing but runoff, but with a trickle in summer with a hose, it keeps water all year. It has been fairly clear until last year. Now it is muddy and I can only see fish if they are 6 inches from the top. I have feeder goldfish that are now koi size, billions of bluegill and probably a fairly large number of lg. mouth bass. I think my pond is extremely overpopulated. Also, I have corrals above the pond that has runoff feeding into the pond. I clean the corrals, but can't get everything. I'm thinking of letting the pond dry up, save the goldfish and mosquito fish (I know you are all probably thinking I'm an idiot at this point), but the bluegill and bass are of no use. The pond is, like I said, runoff water and I wouldn't eat anything that I caught. This is strictly a pond for enjoyment. Also, I have never siphoned or dredged the pond in the 6 years that I have owned the property. There is a lot of clay soil around here. Any advice would be helpful. I'm sorry to post on somebody else's post, but can't find how to post my own question. Ann
