Russian River: toxic algae advisories

Russian River, Mendocino County. See all Mendocino County waters.

What the state's records say

The state's latest record, from Dec 15, 2022, recommends no advisory.

Last advisory on file: Nov 14, 2022.

That reflects what the state knew on that date. It is not a finding that the water is safe now: blooms can return within days, and many are never reported.

Before you go, check the state's official algae page and any signs posted at the water.

Dogs at Russian River

The state's latest record, from Dec 15, 2022, recommends no advisory. For Russian River, that is not the same as an all-clear for today. Look at the water before your dog goes in: keep it out of green, blue-green or scummy water and away from mats on the shore.
