Hello,

This is my first post to this site. Alot of great info here! I am thinking of building a small pond in my backyard but I'm not sure if I can do it.

First, the pond will be in a low lying area between two slopes and hopefully will be filled by runoff and rain.

Second, it will probably only be about 20x30'. Our soil is heavy red clay, so I wan't to build it without a liner.

Is a pond this small possible without a liner? How deep should it be to minimize evaporation? The area is on flat ground; will a spillway be necessary (I live in the piedmont of SC)?
I have a neighbor with a grading business, so I can get the area excavated for cheap or free. Any answers would be greatly appreciated.
