Invasive Species Outbreak at Lake George Confirmed as Threat to Local Ecosystem
LAKE GEORGE, NY – An invasive species outbreak has been officially confirmed in the waters of Lake George, prompting urgent containment efforts from state environmental authorities, officials announced Tuesday.
What is the situation? The New York State Department of Environmental Conservation has identified a rapidly spreading population of Hydrilla verticillata, a highly aggressive aquatic plant, in the southern basin of the lake. This invasive species is known for forming dense mats that choke out native vegetation, disrupt water flow, and impair recreational activities such as boating and fishing.
Who is affected? Local residents, business owners near the shoreline, and recreational users of the lake are the primary groups impacted. The invasive species threatens the lake's multi-billion-dollar tourism economy, which relies on clean water and thriving aquatic life. Authorities are urging all boaters and anglers to follow strict decontamination protocols to prevent further spread.
When did this occur? The infestation was first detected during routine ecological monitoring on June 10, 2025, though officials believe the invasive species may have been present for several months prior to detection.
Where is the outbreak located? The affected area is concentrated near the lake's southern shore, encompassing roughly 12 acres of water between Hiawatha Point and Dunham’s Bay Marina. Environmental teams have deployed containment booms and are conducting diver-led surveys to map the full extent of the invasion.
Why is this significant? Hydrilla is considered one of the most destructive aquatic invasive species in North America. It grows up to one inch per day, can fragment and spread with minimal water movement, and has no natural predators in Lake George. If left unchecked, it could displace native fish habitats and reduce oxygen levels in the water, leading to localized die-offs.
How is this being addressed? State and local agencies have initiated a multi-phased response plan, including chemical spot treatments with NYS-approved herbicides and manual removal by certified
