PINTO & KELLY LAKES ADVISORY
Pinto and Kelly Lakes are subject to seasonal blooms of blue-green algae (cyanobacteria) that can release harmful toxins. The City of Watsonville monitors Pinto Lake at the City Dock to determine if microcystin (a cyanobacterial toxin) is present. Results for the most recent samples collected on February 27, 2019 are:
- Microcystin: Not Detected (<1 part per billion)
- Advisory status-No advisory in effect
Please note that Pinto Lake is currently closed because of extremely high water levels. It is important to avoid swimming, wading, and other water-sports during a cyanobacterial bloom. When toxins are present in the lake, you could be inadvertently exposed from direct skin contact, swallowing water, or inhaling droplets. Cyanobacterial toxins can cause rashes, skin or eye irritations, stomach upsets, or other reactions. Also do not allow your pets to enter the water. More information harmful algal blooms is available from the California Department of Public Health and the USEPA.
