Terramuggus Lake is an 83 acre water body 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. 

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.

Potamogeton bicupulatus and 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.  An Isoëtes sp. was abundant in some areas with shallow water and rocky substrate.

Potamogeton epihydrus was recorded in several small patches throughout the lake. Najas flexilis was found in one location on the southwest side of the lake, and an Eleocharis sp. was recorded in one location on the eastern side.
