Beaver Pond, Meriden
Beaver Pond

Beaver Pond is a 31.9-acre pond located in Meriden, CT. There are only a few residential houses and a Boy Scout camp along the western side. A railroad track runs along the eastern shore with an industrial building site in the southeast. There is no public boat access, but a town park along the southern shore allows for recreational use such as fishing.

The CAES IAPP vegetative survey found 15 species of macrophytes present. One species, Eurasian watermilfoil (Myriophyllum spicatum), was invasive. This plant was found growing predominately along most of the pond with a few smaller patches in the northwest corner.

Coontail (Ceratophyllum demersum) was the most dominant plant. It covered almost the entire surface except for one small area just north of the center of the pond where the water reached a depth that prevented sunlight from reaching the bottom. Coontail was found in 100% of the 50 transect points with an average abundance of 4. Western waterweed (Elodea nuttallii) and Canadian waterweed (Elodea canadensis) were also dominant, covering much of the southern and eastern half of the pond. Large-Leaf pondweed (Potamogeton amplifolious), Robbins’ pondweed (Potamogeton robbinsii), and water star-grass (Zosterella dubia) were found frequently growing together. A large patch of all three species was along the eastern portion of the pond with smaller patches in the south. A few scattered small patches were also present along the northern and western shoreline. White water lily (Nymphaea odorata) and yellow water lily (Nuphar variegata) were found in multiple patches sporadically.

The southwest cove was rich in species with an average depth of 1.4 m. These species included: coontail, Eurasian watermilfoil, Canadian waterweed, western waterweed, Robbins' pondweed, large-leaf pondweed, water star-grass, and yellow water lily.

The least dominant plants in the pond include small pondweed (Potamogeton pusillus), greater duckweed (Spirodela polyrhiza)lesser duckweed (Lemna minor). Small pondweed was present in small patches all around the pond. Lesser duckweed was found in one small patch in the eastern corner, and greater duckweed was found in one small patch on the southwest shore above the cove.
