.Eutrophic lakes are the most productive. They have a large diversity of fish, high levels of nutrients, and are often shallow because of sedimentation and the depositing of organic material. These lakes are subject to frequent algae blooms. The water in a eutrophic lake will be murky because of the high levels of phytoplankton and organic matter in the water column. Lake Lacawac is a eutrophic lake!
