Lake Terramuggus, Marlborough
Lake Terramuggus is an 83-acre waterbody owned by the Town of Marlborough. It has a maximum depth of 43 feet and an average depth of 21 feet. Homes have been built around most of the lake with much of the remaining area municipal or lake association beaches. The lake has a boat launch open to Marlborough residents only. Motors greater than 3.3 hp are not allowed.
Lake Terramuggus is an oligotrophic lake with low diversity and low abundance of aquatic plants. Only seven submerged species were found during our July 2004 survey. None of them were invasive species. Plants grew sparsely in widely scattered patches. Some areas supported filamentous algae or charaphyte, but no plants or algae grew over most of the lake bottom.
Snailseed pondweed (Potamogeton bicupulatus) and western waterweed (Elodea nuttallii) were the most abundant vascular plants. They were found in patches throughout the lake and covered the substrate in a cove in the lake’s southeast. Quillwort (Isoëtes species) was abundant in some areas with shallow water and rocky substrate. Ribbon-leaf pondweed (Potamogeton epihydrus) was recorded in several small patches throughout the lake. Slender naiad (Najas flexilis) was found in one location on the southwest side of the lake, and spikerush (Eleocharis species) was recorded in one location on the eastern side.
