Jimmy,
We have about 1 1/2 acre pond. Maximum depth is 15 feet.
Why did you have to remove the dock? I'm looking into making a floating dock.
Have you thought about a wind powered aerator? I'v read that they work well.
How old is your pond? It's good to hear that it wintered over well with last winter as it was a bad one.
Need to get togetheer some time. You are not that far from us.
Here are some recent photos of our pond:
