Welcome to the Clear Lake Aquatic Website!

This site is an "information repository" for many of the workings about Clear Lake, California. Our aim is to provide information and links about aquatic properties of the lake, such as fish species, water quality, algae, invasive species and lake ecology.

This website also provides an "agency directory" with links to local, regional, state, and federal agencies and organizations.

We hope this website will develop dialog and expand the knowledge of the Clear Lake watershed.
