The Nechako Canyon, also known as the Grand Canyon of the Nechako, is a canyon on the Nechako River in the Central Interior of British Columbia, Canada, located between Cheslatta Falls and Knewstubb Lake, which lies immediately above the Kenny Dam, which forms the Nechako Reservoir. Cheslatta Falls, 18 m in height, is the final leg of the Cheslatta River and cascades into the Nechako at its confluence. The river-bed in the canyon is mostly dry due to the Nechako's diversion.
