Recreational water quality monitoring has ended for the season on November 4, 2022
We will resume monitoring for harmful algal blooms and waterborne pathogens in summer 2023. HABs may be present in Utah water bodies year-round. If you are recreating, avoid areas of scum, know how to recognize the signs of a harmful algal bloom, and learn how to protect yourself and your family, including dogs.
