Documents and Reports

The Clear Lake Annotated Bibliography contains 302 references (journal articles, reports, books, videos) about Clear Lake's history, water chemistry, fish fauna and more. TIP: If you are looking for something in particular within the Bibliography, you can use the "Ctrl + F" function or "Command + F" function for MAC users to quickly search for key words (authors, dates, subjects, etc).

The Document Library, part of the Lake County Department of Public Works, has over one thousand paper documents, from maps to reports to books, going back to 1933. You can search by titles, authors, watersheds, and keywords. Searching by the topics "Water Quality" and "Algae" yielded numerous results.
