Chara (muskgrasses)
You know this one. Most common algae in our lake. Looks like a plant on the bottom of the lake, but is really a algae, made up of single cells. When it dies it floats up on the surface, and has a musty smell. It is mostly beneficial to our lake, except that it continues to grow all summer, and can get out of control.
where: entire lake
Filamentous algae
Filamentous algae are single algae cells that form long visible chains, threads, or filaments. In our lake, much of it looks like green slime cotton candy. These filaments intertwine forming a mat that resembles wet wool. Filamentous algae starts growing along the bottom in shallow water or attached to structures in the water (like rocks or other aquatic plants). Often filamentous algae floats to the surface forming large mats, which are commonly referred to as “Pond scums.”

Wild Celery
Ribbon like leaves resembles thick grass with tips growing to the surface. Leaves have a center stripe of lighter green in the middle. By late summer, they become very thick and make getting in and out of your dock difficult.

Zebra mussels
... an invasive species, first appeared on our lake a few years ago. We all know this one, however there are worse members of the mussel family that we do not have. We must be careful with our boats!
