Plant Survey Results Coming In

Last summer, we engaged Northeast Aquatic Research to do a plant survey of the entire Chateaugay Lake shoreline to help plan for future Eurasian watermilfoil control. The survey team collected samples and made observations at one-acre intervals throughout the shoreline zone where aquatic plants grow—1,090 points in all. The good news is they found tremendous plant diversity in the lake system. They recorded 60 species of aquatic plants, all native except for Eurasian watermilfoil. Unfortunately, Eurasian water milfoil was the plant that occurred with the greatest frequency. It was found at 51% of sites. By comparison, the three native species found most often were tape grass (43%), waterweed (39%), and bassweed (25.5%). Other species occurred at fewer than 20% of sites. The survey report is being finalized and should be available soon for posting on the CLF website.
