War declared on Asian clams at Lake Tahoe

RENO, Nevada ” Scientists are preparing to wage an all-out war against another threat to Lake Tahoe’s famed pure waters: Asian clams.

The clams have turned up in numerous locations along Tahoe’s southeast shore and prompted concern that they could pave the way for even more destructive invasive species such as quagga or zebra mussels.

Scuba divers will be used in a $400,000 project designed to test ways to remove the clams. The effort, funded by the federal government, Nevada and California, is scheduled to begin in mid-March.

The clams are suspected of releasing nutrients that fueled an algae bloom on Tahoe’s east shore last summer. Algae growth threatens to turn Tahoe’s blue waters green.

But scientists are more concerned that the clams could promote an invasion by quagga or zebra mussels and trigger major problems in the lake’s ecosystem.
