LOWER LAKE, Calif. – The next Sierra Club Lake Group general membership meeting will take place at 7 p.m. Wednesday Sept. 19, at the Lower Lake Methodist Church Social Hall, 16255 Second St. in Lower Lake.

Dr. Harry Lyons, professor of biology and ecology at Yuba College, will speak about “Recent and Future Reports on Clear Lake.”

University of California investigators are unraveling details of Clear Lake's biology and geology:  Cecile Mioni and Raphael Kudela (U.C. Santa Cruz) have prepared a report on harmful cyanobacteria and their toxins.  

Cindy Looy and Roger Byrne (U.C. Berkeley) have collected sediment cores to determine the ecosystem's biotic response to past climate change.

From the viewpoint of a community college professor who carefully reads and lectures on university research, how will recent and future findings fit with what we already know about Clear Lake?

This is a rare opportunity to get accurate, comprehensible, up-to-date information from a master of communications, and to learn what is really going on with the lake.

As always the meeting is free and the public cordially invited.
