Bacteria could kill invasive species

The recent discovery of a bacteria that can kill zebra and quagga mussels has raised hopes for private and public organizations fighting to control the environmentally hazardous speciesm according to news reports.

New York State Museum researchers Daniel Molloy and Denise Mayer discovered a bacteria strain — Pseudomonas fluorescens — that can kill zebra and quagga mussels without killing other native species in the ecosystem.

Quagga and zebra mussels have not entered Lake Tahoe, but in the past three years the Tahoe Regional Planning Agency has implemented a lake-wide boat inspection program in an effort to prevent aquatic invasive species from entering into the waters of Lake Tahoe.

The complete story is available at the Tahoe Daily Tribune.

Thunderbird Lodge Lighthouse restored

From "Thunderbird Tales" newsletter

The Whittell Harbor Beacon (Lighthouse) at Thunderbird Lodge has been an East Shore fixture since it was built in 1938.

Early photos show a bridge from the lighthouse parapet to shore, but it appears to have been removed during Whittell’s time.

As the years took their toll, winter storms battered the monument until the
base was all but gone. The beacon was in imminent danger of collapsing as only
a tiny pinnacle of rock remained to support the structure.

After nearly two years were spent obtaining the regulatory approvals and
permits for these emergency repairs, the beacon was saved in just three short
weeks of construction in October.
