The only duck pond construction I have seen was done by the state of Texas near my home town. They basically built a very long dam across a relative flat piece of property. It was designed to back water over about 15 acres not more than 1 ft to 6 inches deep. The only depth in the pond was the bulldozer width trench they dug running Parallel with the dam. Basically the area excavated to build the low height dam. I will say this project was a waist of spending because this area of Texas (Throckmoton county just north of Breckenridge) is very arid. It was built about 15 years ago, I think I saw it full of water once for a couple of weeks. The rains in this area have been few and far between as was the case from my childhood to now. Mesquite country. I can't see how the state boys every thought water would stay for any amount of time at only 1 ft deep given the normal rains and climate in this area. Here is an aerial of it. Only goes to show if you build enough dam you can put a pond on any a land reguardless of what the topo is.
