LAKEPORT, Calif. – The Lake County Library’s lecture series “Know Lake County” presents its next installment on Saturday, March 19, with a program featuring Carolyn Ruttan of the Clear Lake Environmental Research Center.

This free program will take place at the at the Lakeport branch of the Lake County Library, 1425 N. High St., at 2 p.m.

Ruttan, a scientist specializing in invasive species with a current emphasis on aquatics, will address the health of Clear Lake.

Ruttan has worked for Lake County Water Resources for nine years looking after the health of Clear Lake, the largest lake within California and the oldest lake in North America at perhaps 2.5 million years.

The county of Lake has the responsibility to protect the public interest in Clear Lake’s eight beneficial uses including a drinking water source for 55 percent of the population, recreation and sport fishery.

Since moving to Lake County in 2000, Ruttan and her husband have developed a love for one of the most diverse counties in the state, and in particular Clear Lake, a seriously forgotten national treasure.

This led her to co-found the Clear Lake Environmental Research Center to bring permanent science to the shores of Clear Lake to answer the many questions about the ecology of Clear Lake and other eutrophic lakes in the world

Know Lake County’s inaugural series in 2015 proved so popular that the Lake County Library has committed to presenting a second year of lectures about Lake County.

Know Lake County’s family-friendly programs are designed to inform and entertain Lake County residents about Lake County.

All programs take place on the third Saturday of each month from February through December at 2 p.m.

Speakers from an array of disciplines and organizations deliver programs for Know Lake County. Programs scheduled for 2016 include the Lake County Quilt Trail, a panel of speakers on Valley fire memories, the Lake County Fair, Boggs Mountain State Demonstration Forest, the Lake County Symphony Association and the history of education in Lake County.
