Monitoring for recreational water quality on May 23, 2023
BE CAREFUL: Harmful algal mats (benthic cyanobacteria) were observed growing in the water by the Calf Creek Campground and Lower Calf Creek trail. These algal mats were producing dangerous toxins.
If visiting Calf Creek, we recommend:
- Avoid touching or disturbing benthic algal mats (see photo examples here)
- Do not dunk head
- Do not drink water or get it in your mouth
- Do not let pets drink water or eat algae
