Lake Tahoe cleanup plan has clear vision
California regulators have given the go-ahead to a sweeping plan designed to slash by one-third the pollution and soil runoff from the communities and highways that ring Lake Tahoe over the next 15 years.

The regulations are part of a long-range effort to restore the lake's legendary clarity to levels not seen since the late 1960s.

The California State Water Resources Control Board on Tuesday approved the first phase of a 65-year project to restore visibility to a depth of 100 feet - up from about 70 feet today. The plan, expected to be approved within months by Nevada and federal regulators, would limit erosion and discharges of phosphorous and nitrogen from four counties, one city and transportation departments in two states.
