             Pinewood Lake, which has an area of 60.2 acres, is controlled by a lake association, which manages a beach on the lake’s southern end and prohibits use by non-members. An unimproved boat launch area exists at the lake’s north end; gas motors are prohibited. The sides of the lake have been developed with private residences, and the surrounding watershed also is heavily developed. Public sanitary sewers serve all homes in the area.

             

            An invasive species, Najas minor, was the most abundant aquatic plant recorded during a September 2004 survey of Pinewood Lake. Najas minor, an annual plant, occurred widely around the lake, primarily in water less than 8 feet deep. It was one of 10 aquatic plants recorded during the survey.

           

              Najas minor covered the bottom in the shallow north end of the lake.  Vallisneria  americana was found in small patches in this area, and individual plants of Potamogeton pusillus and an Eleocharis sp. also were recorded. Vallisneria americana formerly was more abundant in Pinewood Lake and had been treated with pesticides because of residents’ concerns with its abundance. Vallisneria was found during the 2004 survey in scattered patches around the lake.

           

            Plants were confined to shallow coves on the western side of the lake. Najas  minor was most abundant, occurring with Vallisneria americana.  Myriophyllum humile, Isoëtes echinospora, Nuphar variegata and Eleocharis sp. occurred in one small cove, with Najas minor and Vallisneria americana.

           

            Several small patches of Potamogeton bicupulatus were recorded at the northern end of the lake and in a cove on the western side of the lake. Farther south along the western shore and along the southern end of the lake, the bottom was largely covered by Najas minor, with some patches of Vallisneria americana and Potamogeton bicupulatus..

           

            Vegetation was patchy on the eastern side, although Vallisneria americana was more abundant than elsewhere. Patches of Isoetes echinospors, Potamogeton bicupulatus, Potamogeton pusillus, Myriophyllum humile, Nuphar variegata and Najas minor also were recorded.
