Sago Pondweed is thick. Which makes it difficult for bass and other predators to effectively forage in. This means your BG and others have a safe refuge to take cover in. Depending on your goals, this can be a good or a bad thing. However, sago pondweed is readily eaten by grass carp. It is a native aquatic plant and not overly invasive. There are far worse aquatic plant species out there.
