Mill Park Pond is a 3.6-acre pond located in Newington, CT. The pond is surrounded by a public park, Mill Pond Park, and has an outlet covered by a footbridge. No boats are allowed. 

Our September, 2009 aquatic plant survey found the native species common duckweed (Lemna minor), coontail (Ceratophyllum demersum), and bur-reed (Sparganium species) and the invasive species common water hyacinth (Eichhornia crassipes) and curlyleaf pondweed (Potamogeton crispus). Common water hyacinth was observed only in the south end of the pond, while curlyleaf pondweed was found only by the outlet. Coontail was observed throughout the pond while common duckweed was found along the ponds edges and towards the center of the ponds southern section. The population of common water hyacinth is being closely monitored to determine if it is overwintering. Because curlyleaf pondweed is more prevalent in the spring, our survey may be underestimating its area and abundance. This pond was checked again in 2010, but no trace of common water hyacinth was present due to either physical removal of the plant or an inability to survive the winter.
