Update November 2, 2020

The Utah Division of Water Quality’s water recreation season runs from May 1 through October 31. At this time, no further monitoring or sampling for harmful algal blooms or waterborne pathogens at priority water bodies will be conducted until May 2021.

This does not mean that the potential for harmful algal blooms or waterborne pathogens has ceased. Please remain aware while recreating in or near water bodies and for information on how to keep yourself, your family, and your pets safe, please visit:


Update August 19, 2020

Panguitch Lake was sampled 8/12/2020 and had a concentration (14K cells/ml) of toxigenic cyanobacteria (Microcystis) which is below the recommended Warning advisory level (100K cells/ml). However, because elevated levels of toxigenic cyanobacteria have been quantified, we are highlighting this result as a Health Watch.

A Health Watch is not a formal recreational advisory, but rather an indicator that a bloom may exist or become more severe. Indicators can include visual reports, but in this case observations were quantified in a laboratory. Toxin results are pending.
