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 provided services since 2008, including mapping and monitoring surveys, as well as initial on-site control work. Private contractors for hand-harvesting services have included Aquatic Invasive Management (AIM), from 2010 through 2017, and the firm of Invasive Solutions Dive Company, from 2018 through the present. Each year, we receive reports of the contractors’ control activities and results.
