   Lower Bolton Lake is a 175-acre water body with substantial residential development near its shoreline.  The maximum depth is 20 feet and the mean depth is 11 feet. There is a town beach and a state-operated boat launch on the southeastern shore, which allows motors.    

   Vegetation is sparsely distributed along the shoreline.  Almost all of the vegetation is found at depths less than 9 feet.  Charaphyte, Isoëtes echinospora, and Sagittaria sp. were found most frequently during our July 2005 survey. The invasive Myriophyllum heterophyllum was found in a cove on the western shore as well as Elatine minima, Isoëtes echinospora, Potamogeton amplifolius, Vallisneria americana, Najas flexilis, and Sagittaria sp.  Potamogeton pusillus, Utricularia purpurea and Utricularia radiata were both found in one small patch each on the east side of the lake.  Gratiola aurea was found in two small patches in the south, while Ceratophyllum demersum was found in multiple small patches in the north and south sections of the lake.  Elodea nuttallii was also found in the south, as well as on the west shore with Nymphaea odorata.
