I’ve been toying with the idea of building a 1/4 acre pond on my property for irrigation purposes. I love a green lawn but it is taxing on my well.

I did the mason jar soil test and my soil is almost entirely sand. My property is a hill at which the bottom is wetlands followed by a river about 800 feet back. The water level at the bottom is very high. I dug down about 2 feet at the potential pond site and with in 120 minutes had 8” of water. Keep in mind we are in a drought in nh and it is July.

Can a pond be as simple as a hole in the ground in a place where the water table is very high?

Do I need to be concerned with the right amount of clay for water retention give the table is so high?

Are there examples of a build like this on the forum? Any suggested reading specific to this pond type if it can be don?
