Beware the Blooms: Understanding and Managing Harmful Algal Blooms in New York’s Waterways

Harmful Algal Blooms (HABs) are a growing concern for swimmers and boaters in lakes, ponds, and streams. These blooms can create unhealthy conditions for people and pets, leading to symptoms like diarrhea, nausea, vomiting, or throat irritation. Officials have recently issued a Harmful Algal Bloom Advisory for Conesus Lake in Livingston County, which remains in effect.

Factors contributing to the formation of HABs include certain nutrients in the water, warm temperatures, and calm winds. These blooms are composed of cyanobacteria, also known as blue-green algae, which are naturally present in aquatic systems. HABs can turn the water green and form a thick scum on the water’s surface.

Efforts have been made to control the outbreaks of HABs by reducing phosphorous and nitrogen runoff from farms and sewer systems into bodies of water. New York state tracks reports of harmful algal blooms on the Department of Environmental Conservation (DEC) website. It is important for swimmers and boaters to be aware of these risks and take necessary precautions while enjoying their time in the water.
