Hamlin Pond is in an intensively developed area, with condominiums along the southern shore and highways running along the northern and eastern sides. A small swamp is located on the northwest side of the 12 acre pond, extending to the west along the north side of a stream that enters the western side of the pond.          

Ceratophyllum demersum, a native submerged plant, was the most abundant aquatic plant species during our August 2005 survey. It occurred in an uninterrupted band around the edge of the pond, growing densely from the bottom to the surface in up to 6 feet (2 m) of water.  Nuphar variegata occurred in several large patches around the edge of the pond and grew all along the northwest shoreline.  Potamogeton foliosus also grew on all sides of the pond, but was found in much smaller patches.  The invasive Myriophyllum spicatum was recorded only at a boat launch on the pond’s southern shore along with Elodea nuttallii and Potamogeton amplifoliusElodea nuttallii also was found in the eastern edge of the lake, while Potamogeton amplifolius also was found on the western edge of the lake along with Lemna minor and Wolffia brasiliensis.  Plants were not found in the pond's center.
