I'm assuming that you want to get it done in a day. I thnk you might be pushing it with the smaller one, depending on how much work you have to do on the other pond, and how far you want to move the dirt that you dig out.

The smaller fish will like it, but how will you keep the LMB out? I've had them swim in 4" of water to get to a small pool like you describe, then swim back out for deeper water if I walked up.
