The water behind the artesian pool was originally supposed to be a wetland. Fish and Wildlife said it would not hold water so I went a bit deeper, and since it did hold water, it is 3 to 4 feet deep which supports fish that get in during flooding, but often experiences partial kills in summer heat. I think it is under .75 acres. We call it the lower duck pond because a similar depth, but smaller duck pond sits above it (to the left in the photo). They have produced some nice warmouth at times, and the muskrats love them, which a trapper friend/neighbor enjoys.
