The big pond has never had duckweed or watermeal.(FA to the max) It is only eight feet at the most but gets a lot more wind. Most duckweed and watermeal problems exist in calm water surrounded by trees.
The big pond is also the course irrigation pond. We pump water from the river into the pond and out to the course. Challenging during the last few years of drought. Pump runs 12 hrs. a day and sometimes the pond will still drop a few feet.
