Rochester, NY, September 17, 2026 —
The Livingston County Department of Health has issued a harmful algal bloom (HAB) advisory for Conesus Lake. The advisory was put in place after a lake-wide bloom was observed, raising concerns about potential health risks associated with the presence of toxins.
Residents and their pets are strongly advised to avoid any direct contact with the waters of Conesus Lake. Harmful algal blooms can produce toxins that may cause a range of health problems in humans and animals, including skin irritation, gastrointestinal distress, and more severe effects if ingested. The specific type and concentration of toxins present in this bloom have not been detailed in the advisory.
Harmful algal blooms are often characterized by a discolored or scummy appearance of the water, though they can also be present without visible signs. These blooms are frequently linked to environmental conditions such as warm temperatures, sunlight, and nutrient enrichment from sources like agricultural runoff or wastewater.
The Livingston County Department of Health is monitoring the situation. Further updates regarding the extent of the bloom, potential resolution, and any changes to the advisory will be provided as information becomes available. The department emphasizes that caution is the primary measure for ensuring public and animal safety during this period. Information regarding the contractor responsible for monitoring or remediation efforts was not provided. The specific timeline for the bloom’s emergence or anticipated duration was also not specified.
Health officials recommend that individuals who come into contact with affected water should wash their skin thoroughly with soap and water. If symptoms occur after contact, individuals are encouraged to seek medical attention. Pet owners should be particularly vigilant, as animals can be susceptible to toxins from ingesting or swimming in contaminated water. The presence of a fine or penalty for any related violations was not mentioned in the advisory.
