I have 3 6" irrigation wells on some of my duck hunting property that pump 400-600 GPM, With the cost being around $10K, same as drinking well, I see no reason not to dig one of these instead of the typical 25-50 GPM wells to keep my pond full if needed, 2 acres. My question is what are the downsides of a well as far as oxygen deprived water, changing water temp and gases that can be in the well water, and how can I overcome these obstacles.
