Aguasabon Falls & Gorge

Visiting Attractions Aguasabon Falls & Gorge
The Aguasabon Falls & Gorge is a breathtaking, must-see attraction in Terrace Bay! Located 1 km west of the Terrace Bay Tourist Information Centre, the spectacular 100 ft. waterfall cascades into the Aguasabon Gorge, with a beautiful ferocity in the spring and a serene grace in the summer and fall. From fractures in the bedrock dating back almost 2.6 billion years, the river flows along the exposed rock located on the face of the Gorge, called “granodiorite.”
With the Aguasabon River being dam controlled, water levels vary depending on the time of year and existing river levels. In the spring time, the water level usually rises considerably due to the melting snow, while in the summer time the water level is comparatively low and relaxed.
The Aguasabon Falls feature an RV-friendly turn-around parking lot, picnic tables and washrooms. The Gorge boardwalk is wheelchair accessible and also serves as one of the many entrances to the 53 km Casques Isles Trail.
The Aguasabon Falls are an intimate and very important part of Terrace Bay’s history.
Come visit and experience the beauty of nature at it’s finest!

History Behind the Creation of the Aguasabon Falls

The Falls were created in the late 1940s when the north end of Long Lake was dammed to ensure an adequate water supply for the Aguasabon Hydro Development, which would power the soon-to-be Township of Terrace Bay and the pulp mill. The diversion created the man-made Hays Lake and the spillway created the Aguasabon Falls. The project diverted water traditionally destined for Hudson Bay instead to Lake Superior and had an effect on raising water levels in the Great Lakes.

The Construction of the Hays Lake Dam
As of today, the flow of water at the Aguasabon Falls are controlled by the Ontario Power Generation Company (OPG) and fluctuate based on the amount of rainfall and existing water levels required at Hays Lake to effectively produce Hydro-electric power.
