Annual
Tahoe Report Says Asian Clam Invasion Is
Growing Fast (Aug 18, 2009) University of California - Davis.
The annual Tahoe:
State of the Lake Report describes the effects of a spreading Asian clam
population, including putting sharp shells and rotting algae on the mountain
lake's popular beaches, possibly aiding an invasion of quagga and zebra mussels,
and affecting lake clarity and ecology. The report, issued annually since 2007,
is intended to give the public a better understanding of the changes occurring
in Lake Tahoe on a year-to-year basis and to place current conditions within
a historical perspective.
