Oroville, Calif. - State Parks and Department of Water Resources Officials say a significant blue-green algae bloom has been discovered in the North Fork of Lake Oroville.
While it doesn't pose a danger to swimmers, they say it's a good idea to avoid it.
Officials confirm they are actively monitoring the algae, and testing for toxins. Lab tests Thursday morning turned up trace levels of a toxin, but it's far below the level that causes a health concern.
The clinical name for blue-green algae is Cyanobacteria.
It's not uncommon in the lake during the summer months. It appears as bright green particles that form streaks, clumps and mats in the water.
