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 water quality and clarity.

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 for years to come.     

Management efforts undertaken once an invasive species has established itself in the Lake are difficult and costly.  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 to manage the clam.       

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 boat launches to giving talks for area community groups and schools.  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.

We are also active in monitoring, mapping, and management. Often our management activities engage a youth group in community service.
