Here are some pics. Pond is about 1/3 acre and 8'-10' deep with pretty steep sides. If I walk in the water about 6' it's about 5' deep. The water that feeds it comes from ground water, a spring that I found when I dug my house and we piped to the pond, two drainage tiles, and in the middle of summer I pump well water that is set up on a timer and runs for about 2 hrs each night. I have an outlet that basically is the other side of the drain tile that was cut off when digging the pond. I have used some cutrine to help the algae that get out of control occasionally and have added beneficial bacteria. I have marginals planted around the pond and some lilies. I am not after completely eliminating the pond weed just controlling it so we can fish and the kids aren't afraid to swim in it.
