The river has a rich cultural history, as it was an important fishing ground for Indigenous communities and later played a significant role in the logging industry. Today, the river is used for recreational activities such as kayaking, fishing, and swimming. There are two main dams on the river, the Denny's River Dam and the French River Dam, which were constructed to regulate water flow for hydroelectricity production. The river also feeds into the French River Reservoir, which is used for domestic and agricultural purposes. The Denny's River and its surrounding ecosystem are an important part of the local community and contribute to the region's natural beauty.
