The Tarn

The Tarn

The Tarn is an eight acre (0.032 square kilometer) pond in Bar Harbor. Its maximum depth is 4 feet (1.2 meters) and the average depth is 3 feet (0.9 meters). The surface of The Tarn is 97 feet (30 meters) above sea level. This pond is eutrophic, that is, it has a large amount of vegetation and little dissolved oxygen. The turbidity of The Tarn is also very high. The photograph above shows the north end of The Tarn with a great deal of vegetation in the water. The photograph below was taken from a different angle showing that parts of The Tarn have little vegetation. However, The Tarn is more of a marsh than a pond.

The fish in The Tarn include Brook Trout, Minnows, Hornpout (Bullhead Catfish), Banded Killifish, Ninespine Stickleback, Pumpkinseed Sunfish and American Eel.

The photograph below was taken from the outlet of The Tarn at the north end. The outlet is Cromwell Brook that flows through Great Meadow and into Frenchman Bay at Cromwell Cove. The source of water for The Tarn is a small brook at the south end and drainage from Champlain and Dorr Mountains.

The Tarn is located between Champlain and Dorr Mountains to the west of State Route 3 in the Town of Bar Harbor. There is a parking lot at the north end of The Tarn west of State Route 3. The flow of water is substantial in spite of the small size of The Tarn.
