===Harmful algal blooms in Utah Lake===
There are several [[cyanobacteria]] species that are especially common when phosphorus levels and temperature, among other unknown criteria, are favorable for harmful algal blooms.<ref name="Descy, J.P. pp. 129-138"/> These are Aphanizomenon flos-aquae and Dolichospermum flosaquae species, both of which produce [[cyanotoxins]].<ref>Rosen, B.
