Thanks!, I'm really happy with how it turned out, and frankly I'm kind of surprised. It'll probably require some ongoing revision at some point, but so far, so good.

I'm a little leary about what might happen during a dry spell in the middle of the summer (for example, will the springs reverse direction and start leaking more water out of the pond?), I guess we'll see.

I think I'll wait at least a year before considering any stocking (rainbow trout).
