But in 1732 surveyor Normandin considered this an error, who referred to the Necoubeau as a tributary to Lake Ashuapmushuan that was called Lake Chomonchouane by Laure on his maps of 1731 and 1732. Therefore Normandin renamed the river to Chomontchouane. In 1917, the Commission de géographie officially adopted the modernized spelling of Chamouchouane.

(Salmo salar ouananiche). Newly hatched salmon remain in the river for 2 to 4 years before migrating to Lake Saint-Jean where it remains for most of its adult life. Then, at age 4 to 8, it will return to the river to spawn. While the Ashuapmushuan River has significantly contributed to salmon production for the lake, the salmon population has seen a sharp decline in the 1990s. Despite conservation measures, its status remains of concern.
