Clear Creek: toxic algae advisories

Clear Creek, Shasta County. See all Shasta County waters.

What the state's records say

The state's latest record, from Jun 30, 2021, recommends no advisory.

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.
