Lake George Association's Lake Steward Program

The Lake George Association's Lake Steward Program is an aquatic invasive species education and spread prevention program. Lake stewards were hired for the summer to inspect boats at various boat launches around Lake George. Stewards looked for and removed invasive species, and educated boaters on how to prevent their spread within the Lake and to other lakes. In addition, lake stewards collected data about the vessels entering and exiting the Lake.

The Lake George Lake Steward program sought to help contain the spread of the six invasive species already present in Lake George: spiny water fleaEurasian watermilfoilzebra mussels, Asian clam, Chinese mystery snail and curly-leaf pondweed. The program also helped prevent new invasive species from being introduced into Lake George.

Multiple studies have shown that boats and and recreational equipment are among the main vectors of aquatic invasive species spread. This high risk pathway is also one that we have the ability to do something about. While it can be intentional, often times the spread of invasives is unintentional, with the boater not realizing that there are plants or other species attached to the hull of the boat, entangled in the prop, or caught on part of the trailer or other equipment, or that moving these species around will cause a problem.

The Lake George Lake Steward Program is no longer an active program on Lake George. Currently, all trailered boats must undergo an inspection at a regional inspection station around Lake George before they launch. Additional information about the program can be found at
