Timber Lake, Sherman - 2006

Timber Lake is a small, 12-acre pond in Sherman, CT. It is sparsely developed; most of the perimeter of the lake is forested. A dam allows the level of the lake to be raised or lowered by 1 foot. The water is tannic in color, and there are many tree stumps that have been sawed off just below the surface.

Our September 2006 survey found 18 aquatic plant species, including the invasives Eurasian watermilfoil (Myriophyllum spicatum), water chestnut (Trapa natans), and minor naiad (Najas minor). Most of the southern half of the lake is covered in charaphyte. The perimeter of this section is also sparsely vegetated by slender naiad (Najas flexilis), spineless hornwort (Ceratophyllum echinatum), yellow water lily (Nuphar variegata), and a larger amount of Eurasian watermilfoil. Also in the southwest corner are very small amounts of pickerelweed (Pontederia cordata), watershield (Brasenia schreberi), and large-leaf pondweed (Potamogeton amplifolius).

The northern part of the lake is much more diverse and densely vegetated. The perimeter has patches of bur-reed (Sparganium species), broadleaf arrowhead (Sagittaria latifolia), pickerelweed, an unidentified sedge (Carex), and humped bladderwort (Utricularia gibba). In the deeper waters, the mix of plants includes a spineless hornwort, large-leaf pondweed, slender naiad, small pondweed (Potamogeton pusillus), and sparse patches of Eurasian watermilfoil and water chestnut. Throughout this entire area charaphyte, watershield, and yellow water lily are common.
