A eutrophic body of water, commonly a lake or pond, has high biological productivity. Due to excessive nutrients, especially nitrogen and phosphorus, these water bodies are able to support an abundance of aquatic plants. Usually, the water body will be dominated either by aquatic plants or algae.
Eutrophication occurs when a body of water has too many phosphates.  The most common source of phosphorus in lakes is from agricultural  run off.
