I talked to my dad again yesterday about building a pond. He thinks we should start with site A(refer to original post for location). This site will probably be the easiest to build on. The pond will probably be 3-4 acres with a watershed of 55 acres. The soils are similar to site B.

This picture is looking south. The dam will be just to the left of the road and the water will back up to the right.For this site we may have to worry about backing water onto the neighbors property, so I would like to get a surveyor out to get an accurate elevation.
