scott, glad your pond is doing so well. Mine is supposed to take a 8 inch riser pipe.

Greg, I have 2.25 acres that can contribute to the pond. Some of that is wooded. That doesn't include the wet weather creek in my picture. I have only tied into a half of it's potential and could get the rest with some work. Most of the time it's not flowing though.

I figure the pond will be 8/10 of an acre.

How does that sound to you? The state guy and the pond contractor felt like I had enough watershed, but they didn't measure it, like I did. They just went by eye.
