LAKEWOOD — Several samples from Chautauqua Lake were recently sent to the state Department of Environmental Conservation for testing by the Chautauqua Lake Association to determine if harmful algal blooms (HABs) were present in the water. Last week, several positive test results were confirmed and posted to NYHABS, an online database for HAB activity throughout the state. The CLA and other lake officials have expressed concern over the results and where they appear more prominent.

“It appears that the significant HAB activity is in the south basin of Chautauqua Lake,” said Doug Conroe, executive director for the CLA. “Unfortunately, this early onset is a result of concentrated herbicide use in the affected areas.”

Aquatic vegetation in fresh bodies of water help absorb and eliminate nutrients that cause HABs to form. When that plant life is eradicated from a specific area, the nutrient load raises and HABs can form faster and cover larger areas with little competition. It is an unintended but preventable consequence of large scale herbicide use.

Water samples are collected in random locations from both lake basins and sent in to a certified lab for processing. The results are reviewed and interpreted by the DEC and confirmed cases of HAB activity is posted publicly.

HABs usually form near shorelines in spotty locations, however lake officials are concerned over the fact that open water HABs were also confirmed in the south basin as well.

“Open water HABs specifically relate to overall lake water health. This issue needs to be taken more seriously,” said Conroe.

The CLA’s mission is to provide effective and efficient lake maintenance services for the benefit of all Chautauqua Lake users. As the “Stewards of the Lake,” for 66 years the CLA serves to promote and facilitate the ongoing scientific monitoring of Chautauqua Lake and its ecosystem. The CLA partners with local, state and federal lake management programs and educates the community about Chautauqua Lake’s ecosystem and environmental lake management practices.
