    Aquatic ecologists are concerned with blooms (very high cell densities) of algae in reservoirs, lakes, and streams because their occurrence can have ecological, aesthetic, and human health impacts. In waterbodies used for water supply, algal blooms can cause physical problems (e.g., clogging screens) or can cause taste and odor problems in waters used for drinking. Blooms involving toxin-producing species can pose serious threats to animals and humans.

    algae grow when they have the right condition such as adequate nutrients (mostly phosphorus but nitrogen is important too),light levels,PH temperature etc.Generally the amount of phosphorus controls the amount of algae found in fresh water lake or water body.
