Annual Surveys & Treatment

Each summer since 2008, the Chateaugay Lake Foundation has engaged contractors for milfoil control services, including hand-harvesting and benthic mat placement. In 2012, use of benthic mats was discontinued and hand harvesting is now the primary method of milfoil control.

The Adirondack Watershed Institute (AWI) of Paul Smith’s College has been working as one of our contractors since 2008 and also conducts mapping of milfoil beds and pre- and post-season surveys of milfoil density. The firm of Aquatic Invasive Management (AIM) has been working on Chateaugay Lake since 2010, providing hand-harvesting services. Each year, we receive reports of the contractors’ control activities and results.
