Official update: Three beaches in Canandaigua area remain closed after flooding

  • Staff Report 

Kershaw Park, Deep Run Park, and Onanda Park beaches have been temporarily closed due to high levels of bacteria found in the water.


Laboratory testing revealed the presence of E. coli and other coliform bacteria above New York State beach water quality standards. The closures will remain in effect until further testing ensures the safety of the water. Experts believe that recent heavy rains and flooding may have washed contaminated stormwater into Canandaigua Lake, the source of the heightened bacteria levels.

Health authorities warn that contact with the contaminated water may increase the risk of waterborne illnesses. Despite potentially clear appearances, the water can harbor unseen pathogens. Particularly vulnerable groups include children, the elderly, and individuals with compromised immune systems. Potential symptoms include abdominal pain, diarrhea, vomiting, fever, skin rashes, and infections of the eyes and ears. Anyone exhibiting these symptoms after exposure to the water should seek medical advice.

John Goodwin, Canandaigua City Manager, has reassured residents that the bacteria detected at Canandaigua beaches has not affected the municipal water supply. The supply continues to be treated and tested in line with NY State Department of Health regulations and is safe for consumption. Residents and visitors are encouraged to stay informed about beach closures and to take precautions when visiting natural bodies of water, especially following heavy rainfall.
