            Lake Williams is a 250-acre pond located in Lebanon, CT. Access is by via a private boat launch or through the Lake Williams Campground located on Route 207. It has seven islands in the southern end of the lake. Two have houses on them.

            Our June, 2009 survey found 14 plant species of which only one, Myriophyllum heterophyllum, is invasive. Myriophyllum heterophyllum mixed with Nuphar variegata, Nymphaea odorata, and Brasenia schreberi is abundant in the northern coves and within 30 meters (100 feet) of the shore.  Submerged,  vegetation also occurring in this area includes  are Potamogeton pulcher, Utricularia macrorhiza (formally U. vulgaris), Utricularia purpurea, and  Utricularia gibba.

            In the southern half of the lake, Vallisneria americana and Potamogeton pulcher is abundant along the shoreline. Potamogeton bicupulatus is found sparsely through the lake yet is slightly more common in the southern end and around the island. Also found sparsely around the islands includes Eriocaulon aquaticum, Najas guadalupensis, and Eleocharis spPotamogeton epihydrus was only found in the coves, to the left of the Lake Williams Camp Ground swim area.

                Lake Williams has been treated recently to control Myriophyllum heterophyllum.
