DRAFT
Mossy Point Boat Launch
6 of the 15 samples found on boats at Mossy Point were invasive species. All of these
specimens were removed from boats about to enter the lake. 5 specimens of Eurasian
watermilfoil and 1 specimen of curly-leaf pondweed were removed from boats.
The 6 invasive species came from boats that had last been in 3 different lakes, one of which
was Lake George itself (figure 9). This is not surprising considering the large amount of
Eurasian watermilfoil growing in the water right at the boat launch.
Dunham’s Bay
11 of the 28 samples from Dunham’s Bay were invasive species. All 4 different invasives
were also found at this launch. There were 3 zebra mussels, 3 water chestnut, 4 Eurasian
watermilfoil, and 1 curly-leaf pondweed. The water chestnut saves are especially important.
Dunham’s Bay is the ideal habitat for water chestnut, and there is a historical record of the
plant growing there from years ago. The population was removed and has not been seen in
years and we certainly do not want it to make a come back.
The 11 invasives came from boats that had last been in 6 different lakes. Once again, Lake
George itself was listed. The 3 water chestnut samples came from 3 different waterbodies:
Saratoga Lake, Lake Champlain, and the Mohawk River. 1 waterbody was from outside of
New York and two of the waterbodies were rivers (figure 10).
