Transportation
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. The lake and rivers were an early transportation corridor from the coast to the interior, and encouraged the first incorporated European settlement of interior Maine in 1762. Sebago Lake was linked to Portland harbor by the Cumberland and Oxford Canal in 1832. The outlet to the Presumpscot River was controlled for the canal by the Eel Weir Dam and the Head Dam, owned and operated by the S. D. Warren Paper Mill after the canal was replaced by a railroad.
The lake was a comparatively safe place for training military pilots from NAS Brunswick about flying over water; but several navy planes were lost over the lake during World War II. A TBF Avenger from the Lewiston Naval Auxiliary Air Facility ditched and sank near Raymond on 16 August 1943. Two low-flying British F4U Corsairs from Brunswick were lost after a mid-air collision over the lake near Raymond on 16 May 1944; and a third Corsair flew into the lake on July 16th.
