            Bigelow Pond is a 25 acre natural pond located within Bigelow Hollow State Park.  The maximum depth is 15.4 feet and the mean depth is 7.5 feet.  No residential development has been permitted near the pond; instead it is bordered by woodlands.  A boat launch is located on the eastern shore; however, all gas-powered motors are prohibited.

            Unidentified sedges were the most widespread vegetation, found in the waters of the north and mid sections of the pond, at depths of less than 12 feet.  Nymphaea odorata was observed on the edges of each island as well as on the shoreline on each side of the pond.  Brasenia schreberi mostly occurred alongside Nymphaea odorata but at deeper depths. The following species; Charaphytes, Eleocharis acicularis, Elodea nuttallii, Eriocaulon aquaticum, Isoëtes sp., Ludwigia palustris, Nuphar variegata, Potamogeton bicupulatus, Potamogeton epihydrus, Potamogeton gramineus, Sagittaria sp., Utricularia geminiscapa and Najas flexilis, were found in small to medium size patches in the north section of the lake and around the large island in the middle of the lake.  Utricularia radiata, Utricularia vulgaris and Utricularia purpurea also were found in small to medium patches in the same places as the aforementioned species, as well as, in the south end of the lake.
