Toponymy
This body of water is located in the hollow of a kettle formed following global warming 10,500 years ago, which followed a glaciation whose cover was about three kilometers thick. Located in the municipality of Hébertville, it is located on the old waterway that once connected the Saguenay to Lake Saint-Jean via Lake Kénogami. A plateau, where the Beau Portage lake is located, allows communication between these two lakes. This toponym appears in the form Kinougamichis in the Jesuit Relations of 1672 under the pen of Father Albanel. This name turns out to be a diminutive of kenogami, meaning "small long lake". It was once famous for the multitude of long-tailed frogs that inhabited it and made a continuous croaking. In addition, various spellings have been inventoried for this toponym, including Kinogamichiche, Kinougamisis, Tshnuagamitshish, etc. The toponym "lac Kénogamichiche" was formalized on September 5, 1968, by the Commission de toponymie du Québec.
