Because the fertility of the land varied greatly, logging and log driving quickly became important economic activities. In 1862, the township was officially established as a municipality. That same year, the post office was inaugurated and took the name of the Kazabazua River, a tributary of the Gatineau River. Of Algonquin origin, this name is a deformation of the word kachibadjiwan, from kach (“hidden”) and djiwan (“current”), hence the meaning “hidden current” or “underground river.”

The name Kazabazua was only officially recognized to designate the village starting in 1935, despite its earlier use by most residents. It was not until 1976 that it became the municipality’s legal name.

From the village, standing on the bridge that crosses the river, one can see the water disappear underground. The river reappears a few dozen metres downstream, then flows in rapids before passing under a natural stone arch. In spring, the river’s powerful flow even causes it to rise over the bridges. To admire the waterfalls, a small path running along the guardrail of the south bridge allows, after a short walk, a view of the torrents of water cascading below.
