I have 5 acres. In this 5 acres I have an area that is about 1 acre that I would like to build a pond in the middle of it. Maybe 1/5 acre in size (approx 150'x 50' x 10' deep). My land is flat farm land. No real drainage or anything that I can take advantage of to catch water.

My neighbor has a irrigation well that they use for their farm. I am thinking I can buy water from them to initially fill up the pond (running a temporary pipe 1/4 mile from the well to my pond).

I have a small low spot on my property that fills up maybe 6" deep after a rain and it will hold this water for about a week. I assume I am going to need to add bentonite or a liner to the pond?

My main concern is going to be keeping the pond full. My neigbors well can do the initial pumping, but will my household well be able to keep it full? If it is sealed good what kind of water loss am I going to have due to evaporation?
