Demi-charge in Canadian French means literally "half load." It refers to that part of a canoe's contents that was unloaded at a décharge, which was a shallow spot or dangerous area where a boat or canoe had to be partly unloaded before it could go on. This name therefore dates from the days of the fur trade, and is at a spot where the rapids were bad enough that the boats had to be lightened.

Approximately 70 km north of Fort Chipewyan in Slave River.
