Thanks for all the advice guys. Just a quick update. There were a couple of meetings and the park district is going to take over the upkeep on the ponds as the developer has gone belly up. This seems to be good news. They are going to seed the muddy areas within the next 2 weeks and install aerators (which we found out is a mandatory law in this suburb) within the next month. They will however remove them in Nov every year so we won't have aeration in the winter. I also got more info on the pond itself. It is 1.81 acre feet and about 10 feet deep in the center. How big of a problem would freezing temperatures in the Chicagoland area be for fish? I'm planning on getting the fatheads in next week as things are finally warming up around here.
Thanks for everything
