            Mill Park Pond is a 3.6 acre pond located in Newington, CT. The pond is surrounded by a public park and has an outlet covered by a footbridge. No boats are allowed.  Our September, 2009 aquatic plant survey found the native species  Lemna minor,  Ceratophyllum demersum, and Sparganium sp. and the invasive species Eichhornia crassipes and  Potamogeton crispus.  Eichhornia crassipes was observed only in the south end of the pond while Potamogeton crispus was found only by the outlet. Ceratophyllum demersum was observed throughout the pond while Lemna minor was found along the ponds edges and towards the center of the ponds southern section. The population of  Eichhornia crassipes is being closely monitored to determine if it is overwintering. Because Potamogeton crispus 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 Eichhornia crassipes was present due to either physical removal of the plant or an inability to survive the winter.
