            Batterson Park Pond is located in Farmington and New Britain although it is owned by the City of Hartford.  The eastern side of the pond is residentially developed behind an old railroad bed and a patchy tree buffer.  A state-leased boat launch is located at the south end of the pond; gas motors are prohibited.  The 140-acre Batterson Park Pond supports abundant populations of nine aquatic plant species, including three invasives.

            During our August 2004 survey, the most abundant invasive was Myriophyllum spicatum, which occurred primarily on the eastern side and southern end of the pond, although smaller patches were recorded on the western side and northern end of the pond.  The species was found in water up to 9 feet deep in the pond, which has a maximum depth of 20 feet and mean depth of 14 feet.

            Potamogeton gramineus, Potamogeton foliosus and the non-native Najas minor occurred with Myriophyllum spicatum at the pond’s southern end.  Myriophyllum spicatum occurred with Najas minor on the western side of the pond. The annual Najas species occurred alone in shallow water in some areas, as did Elodea nuttallii.

            A patch of a non-native fern, Marsilea quadrifolia, was found along the shore in the northwest part of the pond, south of a beach used by a summer camp. Even larger patches of the invasive species were recorded in small coves farther south along the pond’s western shore, and the fern was especially abundant in a cove at the southwest corner of the pond, where a stream enters. No trace of the plant was found anywhere up the stream, although a number of pools of quiet water were found, where Marsilea quadrifolia presumably could have grown and been washed downstream into Batterson Park Pond.

            Potamogeton gramineus also occurred along the western side of the pond, in water no more than 3 feet deep. Patches of Stuckenia pectinata, Potamogeton foliosus and Ceratophyllum demersum also were recorded. Vegetation in the northern end of the pond was sparse, although Potamogeton gramineus was found in water as much as 9 feet deep, and patches of Myriophyllum spicatum, Najas minor, Stuckenia pectinata and Potamogeton foliosus were found.
