INCLINE VILLAGE, Nev. (CBS/AP) — Scientists studying invasive species at Lake Tahoe are looking forward to a chance to press for more long-term research when Al Gore returns to an environmental summit next weekend that he helped kick off 17 years ago.
Researchers at the Desert Research Institute and the University of Nevada, Reno manned an electro-shocking boat on the lake this past week, sending electric current through the water near Tahoe Keys to flush out some of the unwelcome aquatic life.
According to reports, more than 30,000 invasive fish have been removed in recent years while researchers try to find ways to minimize their harm to native species.
Some of the work has its roots in the first Tahoe Summit that then-President Clinton and Vice President Gore hosted at Sand Harbor in 1997.
