The name “Kennebago” comes from the Abenaki word “kinnipekw”, which means means “long water”. The Abenaki tribes only had spoken languages, so any words that came from their vocabulary were deciphered from the spoken word and transliterated as close as possible to the Roman alphabet. Therefore, a word in the Abenaki languages can translate to several different similar words in the Roman alphabet. The Abenaki word “pekw” means “water”, and suffixes such as “bago” (as in “Sebago” – meaning “big water”), “bec” (as in “Sebec” – also meaning “big water”), “bagog” (as in “Umbagog” – meaning “shallow water”), and similar suffixes are seen all over areas that were once occupied by Algonquin (the parent language family of the Abenaki languages)-speaking peoples. Therefore, “Kennebec,” and “Kennebago” both mean the same thing, and translate to “long water”.
West Kennebago Mountain once featured a fire tower that was replaced sometime in late 2011 to early 2012 with a radio tower. You used to have to climb the tower to get any views, however, clearing land for the radio tower opened up more ground-level views.
