University of California, Davis, researchers say the waters of Lake Tahoe were clear to an average depth of nearly 70 feet, about what it's been for the last eight years.
The report released Thursday comes after the 2007 Angora Fire dumped runoff from burn areas into the deep Sierra Nevada lake on the California-Nevada border.
Researchers say the lake seemed more affected by ash from last summer's severe wildfires that clouded the water from mid-July through mid-August.
The researchers have monitored the lake since 1968 using a disk that's lowered into the water. Researchers say the lake's clarity isn't declining as fast as it once was.
