The substances that turn our lakes and rivers green each summer come from our lawns and yards. We think of leaves as waste, but to a lake they are food. The algae in lakes love leaves and fertilizers, and when we feed lakes too many chemicals and leaves, algal blooms turn our lakes and rivers green and smelly. Protecting water is everyone’s job What can you do? Simple–remember the land/water connection! What we do to the land we do to the water. Reduce chemicals, clean your streets when the leaves fall from the trees, and when you mow the grass clean your streets and sidewalks. Keep our lakes and rivers clean.
