Sebago Lake is the deepest and second largest lake in the U.S. state of Maine. The lake is convert|316|ft|m deep at its deepest point, with a mean depth of convert|101|ft|m, covers about convert|45|sqmi|km2|0 in surface area, has a length of convert|12|mi|km and a shoreline length of convert|105|mi|km. [cite web | title=Sebago Lake | work=Portland Water District, Portland Maine | url=http://www.pwd.org/environment/sebago/facts.php | accessdate=2006-05-05] The surface is around convert|270|ft|m above sea level, so the deep bottom is below the present sea level.

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.

Water Supply

Sebago Lake is the primary water supply for the Portland Water District, which serves the Greater Portland region and about 15% of Maine's population. The lake's watershed is more than convert|50|mi|km long and covers parts of 24 Maine towns. [cite web | title=Sebago Lake | work=Portland Water District, Portland Maine | url=http://www.pwd.org/environment/sebago/sebago.php | accessdate=2006-05-05]

The lake holds roughly 995 billion gallons of water that on average resides 5.1 to 5.4 years in the lake. The direct watershed is about convert|171|sqmi|km2|0 of land plus the convert|45|sqmi|km2|0 of the lake, and the indirect watershed about convert|190|sqmi|km2|-1 of land plus about convert|28|sqmi|km2|0 of other bodies of water. As of May 1990, roughly 86% of the watershed was forests and fallow fields, 2.5% in active timber operations, 9.3% in residential, agricultural, and commercial use, and 2.2% used for other purposes. Water inflow is estimated at 544 million gallons per day and outflow at 498 million gallons per day, of which 24 million gallons/day are for the water district.

Recreation

In 1938, Maine opened Sebago Lake State Park as one of its original five state parks. The area was a recreation center even before this. The park is now 1,400 acres (mostly forested), open year-round, and has facilities including two public boat launches and a 250-site campground. [cite web | title=Sebago Lake State Park | work=Bureau of Parks & Lands, Department of Conservation, State of Maine | url=http://www.state.me.us/cgi-bin/doc/parks/more_info.pl?park_id=26 | accessdate=2006-05-05] There are also numerous private campgrounds, cottages, and other recreational facilities in the area. Sebago Lake is located in the portion of Maine that the Maine tourism industry refers to as the Western Lakes and Mountains Region.

=Fishing= 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.

[cite web | title=Sebago's salmon | work=Outdoors, MaineToday.com | url=http://outdoors.mainetoday.com/fishing/050515sebago.shtml | accessdate=2006-05-05] 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.
