   Bolton Notch Pond is a 21 acre lake located along Route 44 in Bolton, Connecticut.  Freya Park and Bolton Notch State Park border the lake on the eastern and western sides.  The East Coast Greenway has a trailhead next to the pond and there is a canoe and kayak boat launch onto the waterbody. The lake and its surrounding land are used primarily for recreational activities.  The lake is shallow with a maximum depth of 1.5 meters.

   The CAES IAPP 2011 aquatic plant survey found 24 species, none were invasive.  The most dominant plant was Brasenia schreberi. The plant covered most of the surface of the lake.  Of the two transects consisting of a total of 20 points, B. schreberi was present at 15 of the points.  The next most dominate plant was Nymphaea odorata, also a floating plant.  N. odorata was found in large patches along the northwestern shore and was present in smaller patches throughout the lake.  Other floating native plants that were found in smaller amounts near the shorelines include: Spirodela polyrhiza, Wollfia sp., and Lemna minor.  Utricularia species were also abundant.  Four different species were found: U. gibba, U. machrorhiza, U. minor, and U. purpurea.  U. gibba was the most frequently occurring Utricularia species. It was found at 12 points along the two transects.

   Many shallow water plants were found growing together.  These plants include: Callitriche sp., Elatine sp., Eleocharis sp., Ludwigia sp., Myriophyllum sp., Najas flexilis, Potamogeton natans, Potamogeton pusillus, and Sagittaria species. Plants that were found along the shoreline were: Decodon verticillatus, Pontederia cordata, and Typha species. D. verticillatus was found in large amounts and was starting to dominate some the shallow water regions.
