Marina With Duckweed

Image: Marina With Duckweed

Detailed Description

This image shows an Upper Mississippi River marina covered by excessive duckweed.

Too much nitrogen and phosphorus in water could lead to an overgrowth of free-floating plants such as duckweed and filamentous algae. These overgrowths can result in dense layers of scum on the surface of the waters, and can damage below-surface plants, fish and other lake organisms by depriving them of the oxygen and sunlight they need to survive.
