Lake George Association's Lake Steward Program

Invasive Species Awareness Week

The LGA's Lake George invasive species program seeks to control and prevent the spread of aquatic and terrestrial invasive species in and around Lake George. Invasive species present a primary threat to the renowned water quality and clarity of Lake George, something the Lake George Association is committed to protect.

Education and spread prevention are the most cost-effective ways to control invasive species on Lake George, and the LGA has significant investment in both. The LGA’s broad focus on both aquatic and terrestrial invasive species aims to keep the Lake and its watershed healthy into the next century.

It becomes difficult and costly to undertake management efforts of an invasive species once it has established itself — which is why spread prevention is so important. For example, the Asian Clam will require extensive resources and funding to control. The LGA is playing an active and hands-on role on the Asian Clam Rapid Response Task Force, the group researching and testing options on managing the invader.       

There are 6 known aquatic invasive species in Lake George. Click the above image for a quick overview of each species.

The LGA's invasive species program operates on a variety of levels — from coordinating a lake steward program at events throughout the watershed, to giving talks for area community groups and schools, to actively monitoring, mapping and managing invasives.

Often our management activities engage a youth group in community service.

In addition, the LGA coordinates the Adirondack Invasive Species Awareness Week for the Lake George region every July. LGA staff also give presentations at local, state and national conferences, for organizations such as the Lake George Watershed Coalition, the New York State Federation of Lake Associations, and the North American Lake Management Society.
