Lake Information for Sebago Lake


Sebago Lake is the deepest and second largest lake in the U.S. state of Maine. 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, 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. It is located in Cumberland County, Maine and bordered by the towns of Casco, Naples, Raymond, Sebago, Standish and Windham. The seasonally occupied town of Frye Island is on an island in the lake.

The lake is connected to Brandy Pond by the Songo River and eventually to Long Lake in Naples. The name comes from a local Native American tribe. The lake is drained primarily by the Presumpscot River. Prior to construction of a railroad in 1870, Sebago Lake was linked to Portland harbor by the Cumberland and Oxford Canal. The outlet to the river has been dammed since 1875 by the Eel Weir Dam and the Head Dam, owned and operated by the S. D. Warren Paper Mill.

Fishing Description: 

The lake contains natural populations of land-locked salmon (Salmo salar sebago) and smelt. When the last major glaciers retreated, the entire watershed was under seawater, and populations of these marine animals became established as the land rose and sea waters retreated.

Other game fish that can be found in the lake include lake trout, brook trout, brown trout, smallmouth bass, largemouth bass, and northern pike. Some of these are stocked by the state, either in the lake directly or in connected bodies of water, while others were introduced illegally. The state encourages anglers to kill, hold, and notify them of all northern pike taken in the lake because they were introduced illegally, are not native to the region, and could disrupt the lake ecosystem.
