Algae Everywhere
The Detroit River supports more than 80 species of algae, which provide an important food source for other river animals. Although algae are an important part of the River’s food chain, some nutrients, such as nitrogen and phosphorus found in fertilizers and yard waste, can cause algae to grow excessively and choke out other animals.
Viewer Tip: If you see extra fertilizer or grass clippings on your driveway or sidewalk, try to sweep them back onto the lawn. This way, rain water is less likely to carry them into storm drains, and into the Detroit River.
Seasons: Spring, Summer, Fall
