Visitors to Waterbury Reservoir may have encountered something new at the lake this year: a nice young man with a yellow “Public Access Greeter” shirt on. This summer was the inaugural year for a Public Access Greeter Program at Waterbury Reservoir (FWR), which was established by Friends of Waterbury Reservoir with assistance from the Vermont Department of Environmental Conservation’s aquatic nuisance species grant-in-aid program. A part-time greeter, along with a motivated group of volunteers from FWR, offered invasive species education and boat inspections at multiple launch sites around this aquatic gem in central Vermont.

Vermont’s Public Access Greeter Program had a record-breaking year in 2015 while working to prevent the spread of aquatic invasive species (AIS). Public access greeters educate lake visitors about invasive species and provide courtesy watercraft inspections for AIS.
