Aquatic Invasive Species
Aquatic Invasive Species
Aquatic invasive species are non-native plants and animals that interfere with boating and fishing, threaten native plants and animals and destroy habitat. They are difficult and costly to remove. It is better to prevent their spread. The primary pathway for the introduction of aquatic invasive species into Lake George is recreational boating. Aquatic plants and organisms can adhere to boat hulls, become entangled on trailer bunks or remain hidden in bilges and other compartments.
Therefore, the Lake George Park Commission requires watercraft to be cleaned, drained and dried before use in Lake George. Between April 15 and November 29 all trailered boats are required to undergo an invasive species inspection.
Aquatic invasive species present in Lake George include
36,100 pounds of milfoil were harvested in 2025. There were 30 active milfoil sites. Most sites require repeated harvesting because the roots and fragments are difficult to remove from the sediment. Two sites were treated with ProcellaCOR in 2024 where between 95-100% of the milfoil was eradicated.
