Sebago Lake and Penobscot Bay in Maine, USA44.1N 68.9W
Sebago Lake (lower left quadrant) is the deepest and second largest lake in the USA state of Maine, in Cumberland County. The lake is 316 feet (96 m) deep at its deepest point, with a mean depth of 101 feet (31 m), covers about 45 square miles (117 km2) in surface area, and has a length of 12 miles (19 km) and a shoreline length of 105 miles (169 km). The surface is around 270 feet (82 m) above sea level, so the deep bottom is below the present sea level.
Moving to the east towards Canada, following the condensation trails that run parallel to the shoreline, one comes to Penobscot Bay, Maine. Named after the major river that feeds it, this bay area forms part of the traditional homeland of the Wabanaki Indians, in particular the Penobscot tribe (also named after this river).
