* Increased biomass of phytoplankton
* Toxic or inedible phytoplankton species
* Increases in blooms of gelatinous zooplankton
* Decreased biomass of benthic and epiphytic algae
* Changes in macrophyte species composition and biomass
* Decreases in water transparency (increased turbidity)
* Colour, smell, and water treatment problems
* Dissolved oxygen depletion
* Increased incidences of fish kills
* Loss of desirable fish species
* Reductions in harvestable fish and shellfish
* Decreases in perceived aesthetic value of the water body
