KELSEYVILLE – At 7 p.m. on Tuesday, Nov. 17, the Sierra Club Lake Group will offer a second forum in its "Stewards of the Lake" series on the health and well-being of Clear Lake and its watershed.

The first meeting in this series, held in September, focused on the the severe infestation of cyanobacteria (also known as "blue-green algae") that caused so many problems on the lake last summer, with a secondary glance at mercury pollution and the Sulphur Bank Mercury Mine cleanup.

Now they will turn their attention to invasive mollusks, particularly quagga and zebra mussels, with an expert panel consisting of Invasive Species Council Chair Greg Giusti, Deputy Director of Water Resources Pam Francis and Lakeport City Councilor Suzanne Lyons.

Topics under discussion will include the nature of these diminutive but dangerous creatures, the devastating ecological and economic effects that would result from an infestation in Clear Lake or other local waterways, the concrete steps being taken to keep them out, and the roles that we can all play in this essential task.

These questions and more will be on the agenda during this free-ranging panel discussion, which will be held in Room 203 at Kelseyville High School, 5480 Main St. in Kelseyville.

The meeting is free and open to the public.
