American lotus is just one of the several species of “lilies” or floating leaved plants that grow in Pool 1. It provides shade and oxygen for the fish below, but can also crowd out other plants and fishermen because of its broad, round leaves.
You may have seen the American lotus flower's seedpod and just didn't know it. Also known as "yanqypin," the seedpod is used often floral arrangements.
Over the summer aquatic plants, like this pickerel weed, have been grown in a nursery and planted in some of the deeper scours that have held water through the summer.
