   Burr Pond, located within Burr Pond State Park, is 85.1 acres, and has a maximum depth of 11 feet and a mean depth of 5.1 feet.  A public swimming area exists along the west shore, and the state maintains a boat ramp at the pond’s southern end. Outboard motors are allowed, however, the speed of boats is limited.

   The pond supports lush growth of several aquatic plants, including the invasive Myriophyllum spicatum, which was found growing throughout the pond during our July 2005 survey.  Also found growing in abundance around the lake are Brasenia schreberi, Najas guadalupensis, Vallisneria americana and Utricularia purpureaElodea nuttallii, Potamogeton amplifolius, and Potamogeton epihydrus also occurred around the pond in smaller patches.

   Other species occurred in one to a few small patches including the invasive species, Myriophyllum heterophyllum, which was recorded in relatively deep water in the northern and southern portions of the pond.  Nuphar variegata also occurred in the same areas of the lake as the Myriophyllum heterophyllum, as well as in the western edge of the pond. Gratiola aurea, Potamogeton bicupulatus, and Utricularia vulgaris occurred in the southern and western portions of the pond.  Callitriche sp., Ceratophyllum echinatum, Nymphaea odorata, Pontederia cordata, Potamogeton foliosus, and Potamogeton natans were found on the western edge of the pond.  Isoëtes echinospora occurred in both the western and eastern edges of the pond.  Eleocharis sp. was found only in the shallow water of the eastern edge of the pond, and Utricularia gibba was found in both the eastern and northern portions of the pond.  Utricularia radiata was found in a small patch in the northern end of the pond.
