I bought land and with it a beautiful 2.5 acre spring-fed pond. It is about 6-8' deep in the middle (hard to tell due to much level) and a over half of it less than 2'. Lots of muck. I hear a couple years back it had sewage running into it. It flows out steadily 24/7, 365 days per year into small river. Most times in winter there is at least some open water. It has Northern Pike (one was 36") and some other fish but don't know all species yet. Water clear as could be. Bottom has lots of silt and I would like to get rid of some of it. Cannot afford to drain/dredge, will running a fountain pump this winter help stir things up and start to clean out muck?
