The private 3-acre Wampum Hill Pond was created when a dam was built across a small stream in 1963. The dam is at the south end of the pond. Nine aquatic plants were recorded during our September 2005 survey, and all of them were native species. The entire surface of the pond was covered by plants in the duckweed family, including common duckweed (Lemna minor), great duckweed (Spirodela polyrhiza), and watermeal (Wolffia species). The floating-leaved yellow water lily (Nuphar variegata) occurred in one small patch on the east side of the pond, and the submerged coontail (Ceratophyllum demersum) was abundant throughout the small waterbody. Small pondweed (Potamogeton pusillus) was relatively abundant in a limited area at the north end of the pond. Flat-stemmed pondweed (Potamogeton zosteriformis occurred in three small patches, and slender naiad (Najas flexilis) occurred in two. Marsh primrose-willow (Ludwigia palustris) was recorded in a single location.
