Lewis Creek Association (LCA) recently wrapped up its boat launch steward program at Bristol Pond and Monkton Pond. LCA chose Bristol Pond and Monkton Pond due to their popularity with anglers, recreational boaters, wildlife enthusiasts, and for the natural communities that are present at the ponds. As of 2021, there are three known aquatic invasive species (AIS) in Bristol Pond [European Frogbit (Hydrocharis morsus-ranae), Eurasian Watermilfoil (Myriophyllum spicatum), and Brittle Naiad (Najas minor)] and two AIS in Monkton Pond [Eurasian Watermilfoil and Curly-leaf Pondweed (Potamogeton crispus)]. Therefore, Bristol Pond and Monkton Pond could function as points of introduction for the spread of AIS in the Lewis Creek watershed and throughout the State. The goal of LCA’s program was to prevent the spread of AIS by inspecting watercraft for AIS and biological materials, identifying and removing suspicious specimens, collecting data, and educating the public about AIS spread prevention.

Seventy-three percent of visitors at Bristol Pond and 64% of visitors at Monkton Pond reported that they took AIS spread prevention measures (e.g. cleaning, draining, and drying their boats) prior to inspection. Forty percent of watercraft inspected at Bristol Pond and Monkton Pond had AIS on them. If the boat launch stewards hadn’t intercepted the vegetation on the watercrafts launching into and retrieving from the ponds, 237 watercraft (of the total 579 inspected) could have potentially spread AIS to other bodies of water. LCA found that most visitors are doing their part in keeping our waterbodies healthy by cleaning, draining, and drying their boats and other equipment. Further details on the program’s results can be found at lewiscreek.org/boat-launch-steward-program
LCA’s boat launch steward program was successful in intercepting AIS and educating the public on the issues surrounding AIS. The vast majority of visitors to Bristol Pond and Monkton Pond seemed genuinely excited to have the program at the ponds and many people from the community went to the ponds to see LCA’s boat launch stewards in action. Research has shown that visual inspection and hand removal of aquatic vegetation is extremely effective at preventing AIS from spreading to other bodies of water. LCA’s boat launch steward program could potentially prevent, both directly and indirectly, AIS from spreading to other uninfested waterbodies. LCA hopes to continue the program in 2022, and to coordinate with the Vermont Department of Conservation to organize a volunteer day to remove brittle naiad and European frogbit.
