Iowanate, I'm going to disagree with Blaine about deepening your slopes. Right now it looks like you're showing 5:1. Generally no steeper than 3:1 is recommended for safety reasons, it's very difficult to climb out of a pond with steeper than 3:1. I have two banks that are 3:1 and two at 5:1. I see no difference with weeds on either bank. For swimming, I find even the 3:1 difficult to climb out of. Keeping your slopes at 5:1 will save a lot of money on dirt removal that could go toward enlarging the surface area. The larger surface area will allow your pond to support more fish than deepening it. Mowing 3:1 is a little hairy too, 5:1 no problem.
