Current Water Quality Information
Advisories and Closures: Week of June 27, 2016
Cowell Beach, west of the wharf, extending to the eastern edge of the Dream Inn, has bacteria levels which exceed safe body contact standards. Advisory signs have been placed at beach entry points. This area will continue to be tested and advisory signs remain in place until bacteria levels decline to within safe body contact limits.
All other beaches tested this week met safe body contact standards.
The Santa Cruz Harbor District is currently performing dredging operations to maintain the access channel to the harbor. These operations may from time to time affect Twin Lakes beach. More information may be found at the Harbor website here.
THE FOLLOWING AREAS ARE PERMANENTLY POSTED BY THE COUNTY DUE TO ROUTINELY HIGH BACTERIA LEVELS:
Aptos Creek at Rio del Mar Beach
Porter Gulch Creek at New Brighton Beach
Soquel Creek mouth at Capitola Beach
Schwann Lagoon at Twin Lakes Beach
San Lorenzo River mouth
Neary Lagoon at Cowell Beach
THESE WATER BODIES AND ADJACENT AREAS GENERALLY CONTAIN BACTERIA LEVELS ABOVE SAFE BODY CONTACT STANDARDS AND ARE CONSIDERED UNSAFE FOR BODY CONTACT.
Annual Mussel Quarantine in Effect
The annual mussel quarantine, declared by the California Department of Public Health (CDPH), began May 1, 2016. This quarantine applies to all species of mussels sport-harvested along the California coast, as well as all bays and estuaries.
This quarantine is intended to prevent paralytic shellfish poisoning (PSP) and domoic acid poisoning (DAP) in people who might otherwise consume sport-harvested mussels. Both of these toxins are linked to plankton consumed by filter-feeding animals such as bivalve shellfish, including mussels and clams. The majority of human cases of PSP illnesses occur between spring and fall.
This quarantine does not apply to commercially harvested shellfish.
More information about the quarantine, PSP and DAP can be found on the CDPH Annual Mussel Quarantine - Frequently Asked Questions (FAQ) Web page.
For updated information on quarantines and shellfish toxins call the CDPH Biotoxin Information Line (1-800-553-4133).
PINTO & KELLY LAKES ADVISORY
Pinto and Kelly Lakes are subject to blooms of blue-green algae (cyanobacteria). Cyanobacters such as microcystis are known to produce toxins, exposure to which can cause rashes, skin and eye irritation, allergic reactions, gastrointestinal upset, and other effects. At high levels, exposure can result in serious illness or death. Exposure may occur by ingestion, dermal contact or inhalation. Avoid body contact with blue-green algal blooms. This includes swimming, wading and water-skiing. For more information visit the California Department of Public Health here.
The most recent sample results, taken June 27, 2016, by the City of Watsonville detected no toxin at the City of Watsonville boat launch ramp. (Detection limit is 1 part per billion [ug/L].) Samples taken at Kelly Lake on June 16th by the County of Santa Cruz detected microcystins at 1 part per billion (ug/L).
