   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, Myriophyllum spicatum (Eurasian watermilfoil), was invasive. This plant was found growing predominately along most of the pond with a few smaller patches in the northwest corner.

   Ceratophyllum demersum (coontail, native) 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. C. demersum was found in 100% of the 50 transect points with an average abundance of 4. Elodea nuttallii (Nuttall’s waterweed) and Elodea canadensis (Canadian waterweed) were also dominant, covering much of the southern and eastern half of the pond. Potamogeton amplifolious (large-leaf pondweed), Potamogeton robbinsii (Robbins’ pondweed), and Zosterella dubia (water star-grass) were found frequently growing together. A large patch of all three species were 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. Nymphaea odorata (white water lily) and Nuphar variegata (yellow water lily) were found in multiple patches sporadically.

   The southwest cove was rich in species with an average depth of 1.4 m. These species included: C. demersum, M. spicatum, E. canadensis, E. nuttallii, P. robbinsii, P. amplifolious, Z. dubia, and N. variegata.

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