Mayville, NY - The Chautauqua County Health Department is warning residents and visitors to be aware of harmful algal blooms in local lakes and to take precautions when enjoying outdoor recreation.
 
Harmful algal blooms, or HABs, can produce toxins dangerous to both people and pets. They are most often seen in mid-to-late summer, but officials say they can occur at any time of year.
 
“We want people to know what to look for,” Jessica Wuerstle, Director of Environmental Health Services for Chautauqua County said. “It's different from some of the algae people think of. Blue-green algae is more of a cellular organism, you don't see it very well until it starts to collect and form blooms. Once that happens, the water often looks like pea green soup, or oil spills with vivid green and blue colors, and the danger is that these blooms can release toxins."
 
The department advises avoiding swimming, boating, or fishing in water that appears discolored or has visible algae on the surface.
 
“If you come into contact with a bloom, take a shower with soap and water and rinse that organism off of you and your pets," added Wuerstle. "And if you don't feel well after a day near the water, if you notice a rash or intestinal issues, get medical care."
 
The department of Environmental Health Services says its focus is on preventing water-related illnesses, promoting safe outdoor recreation, and protecting the county’s lakes.
 
New York State and Chautauqua County are also taking steps to reduce nutrient pollution — particularly phosphorus and nitrogen — which contribute to harmful algal blooms. Watershed management plans are in development for several lakes, including Chautauqua Lake and Findley Lake.
 
To further combat this issue, Chautauqua County Executive PJ Wendell and local officials have formed group that includes representatives from the cities, towns, and villages surrounding Chautauqua Lake. This group will collaborate on strategies to improve the overall health of the lake and address ongoing water quality challenges.
 
"A lot of people are very passionate about the lake," Wendell said. "But there is no one answer, no one group that knows everything about the lake, so it is going to take everyone working together. But I feel confident that we will get over this hurdle and will really start to make an impact."
 
While improvements in water quality are expected over time, officials say results may take several years to be fully realized.
