<br/><br/> "Monitoring water quality for the 30,000 plus lakes in the Upper Great Lakes region has never been possible. Water quality measurements have always been taken by hand, and the states have traditionally had the resources to monitor only a small percentage of their lakes." (EARTH OBSERVATORY) This article examines a process in which NASA satellites can be used to monitor lake water quality.
