The Finger Lakes, Great Lakes, and upper Susquehanna River basin have seen the introduction of numerous non- native aquatic species, through spread by ballast water, canals, recreational equipment, and in some cases intentional introductions. This spread can pose a threat to native ecosystems. While there are numerous aquatic invasive species management activities being conducted by multiple agencies and special interest groups within Central New York, the Region 7 Aquatic Invasive Species Program was initiated in 2022 to increase capacity for similar efforts in inland waterways within the Great Lakes and Upper Susquehanna River watershed, as well as provide additional support for ongoing management projects throughout Central New York.
Cayuga Lake Hydrilla Management
Cayuga Lake is New York States longest Finger Lake at 38.9 miles long, and 3.5 miles across at its widest point, with a total surface area of approximately 66 sq miles. Hydrilla, a federally listed noxious weed was first discovered in 2011 in the southern inlet of Cayuga Lake, in Ithaca NY. Because of Cayuga Lakes hydrological connection to the rest of New York through the NYS Canal System, it is important to manage hydrilla to prevent spread throughout the state.
