Rock Creek: toxic algae advisories

Rock Creek, Mono County. See all Mono County waters.

What the state's records say

The state's latest record, from Aug 6, 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.

Dogs at Rock Creek

The state's latest record, from Aug 6, 2021, recommends no advisory. For Rock Creek, 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.
