Abstract: A system for controlling water quality of a reservoir including one or more covers that at least partially cover a reservoir, one or more water quality sensors that sense physical, chemical, and biological water quality characteristics of water in the reservoir, a mixer for circulating/mixing water layers of the reservoir, and a controller in communication with the water quality sensors that processes input from the sensors to circulate/mix water layers of the reservoir that are exposed to an uncovered surface of the reservoir so as to control water quality characteristics of water in the reservoir.
