LAKE OROVILLE, Calif. - The California Department of Water Resources (DWR) is reporting that algal blooms continue to be present in the West Branch and the North Fork of Lake Oroville. Sampling continues weekly and if elevated levels of cyanobacteria or toxins are found, DWR will work with California's Regional Water Quality Control Board and area recreation managers to notify the public and post advisory signs at the affected water body.

There are not any Harmful Algal Bloom (HAB) advisories for Lake Oroville, the Thermalito Forebay, or the Thermalito Afterbay. DWR environmental scientists regularly monitor these locations for cyanobacteria (blue-green algae) and their associated toxins.

Non-toxic algal blooms can be irritating or even dangerous to pets and small children.

The public is encouraged to report algal blooms on the HAB reporting webpage, which can be found by CLICKING HERE.

Below is a video from the DWR that will help you understand the dangers of blue-green algae.

Current releases to the Feather River are 2,300 cubic feet per second (cfs) to meet downstream Bay-Dela water quality and flow standards. Flows through the City of Oroville are at 1,5550 cfs. Flows from the Thermalito Afterbay Outlet are about 750 cfs for a total of 2,300 cfs for the Feather River's high flow channel downstream of the outlet. Throughout the week the flows through the City of Oroville and the Outlet at the Afterbay may fluctuate in order to keep the fisheries healthy.

Dry weather, sunny skies, warmer temperatures, and gusty north winds will drive elevated fire danger today. We'll have even stronger winds, but cooler temperatures on Tuesday. Fire danger will remain elevated. There will also be a chance for light showers in the Sierra on Tuesday and Wednesday.
