New Tahoe Rules to Boost Clarity Limit Discharges

By  | 

RENO, Nev. (AP) - State and federal environmental regulators at Lake Tahoe are moving ahead with new rules and strategies to protect the clarity of the mountain lake's famed azure waters.

California water quality officials approved plans last week to reduce the amount of fine sediments discharged into the lake.

The Lahontan Regional Water Quality Control Board accepted the plans prepared by the city of South Lake Tahoe and El Dorado and Placer counties.

The Reno Gazette-Journal reports the goal is to reduce sediments discharged into the lake from urban runoff by 30 percent over 15 years.

Tahoe's waters were so clear in 1968 that one could see to depths of more than 100 feet. Runoff and algae associated with development have reduced the average clarity in recent years to about 75 feet.
