I have a six acre pond that has areas that are 11 feet deep. However � of the pond averages only 3 feet or so deep. Are there any plants that I could use for cover to help cool the water and keep down algae blooms that will only stay in water 1 to 2 feet deep? If they will grow in three feet of water I am afraid of them taking over the pond? I do not care if they die back in our cold Pennsylvania winters; I just want them to stay in the really shallow water.
