Conservation initiative: Permanently Protecting the Berryessa Snow Mountain Region. The Berryessa Snow Mountain region of northern California is one of the most biologically diverse, yet least known, regions of the state. Located less than one hundred miles from the Sacramento and Bay Area metropolitan regions, the area is a dazzling outdoor wonderland rich in unique natural features and loaded with recreational opportunities. Visitors can find California’s second-largest population of wintering bald eagles, float the thrilling rapids of wild and scenic Cache Creek, witness herds of wild Tule elk, and catch a glimpse of black bears. Opportunities for hiking, camping, botany, birding, hunting, and horseback riding abound. The area stretches over 100 miles from blue oak woodlands near Putah Creek in the south to the sub-alpine habitat of Snow Mountain Wilderness to the north.  For more information visit

Next Meeting: Measure L Town Hall Forum
On at 6 p.m. on Wednesday May 14 Lake Group is partnering with the Lake County Chamber of Commerce to host a Town Hall meeting on Measure L, the countywide half-cent sales tax to preserve and restore our waterways, especially Clear Lake. The Measure will appear on the June 3, 2014 ballot, and will require a two-thirds majority for passage.
This free public forum will be held in the Board of Supervisors Chamber in the Courthouse in Lakeport. Scott DeLeon, head of the Department of Water Resources, will describe the Measure’s objectives, the specific programs it will fund, and its built-in guarantees to ensure that the money will be spent as intended. The presentation will be followed by a Q&A session.  All Lake Group members and other concerned members of the public are encouraged to attend.
Additional Town Hall meetings, all starting at 6PM, are also scheduled:
  • Tuesday April 22, at the Youth Center (4750 Golf Ave) in the City of Clearlake
  • Wednesday April 23, at the Alpine Senior Center (3985 Country Club Drive) in Lucerne
