Today (October 3, 2025), we received notification from Samatha Stevens, Senior Environmental Health Specialist with Sonoma County Environmental Health, that the North Coast Regional Quality Control Board has requested the sign at Pattterson Point be changed from “Check for Algae” to a “Toxic Algal Alert” due to the amount of benthic Cyanobacteria observed at PPP’s beaches.  (More than 15% coverage is the monitoring criteria that triggered changing the sign.
