Ultraviolet Algae Killer Aids Bid To Help Lake Tahoe Clarity

RENO, Nev. (AP) — Encouraged by three years of experimentation, scientists at Lake Tahoe plan to expand the use of ultraviolet light to kill algae and other invasive plants that eat away at the clarity of the mountain water.

Researchers at the University of Nevada, Reno are monitoring the project and collecting data to study the effects of the ultraviolet-C light treatments.

It's the newest tool in a two-decade effort to restore the once-pristine waters in the lake straddling the California-Nevada line.
