The Clearwater River (in French: Rivière à l'Eau Claire) is a river flowing on the east shore of Lake Guillaume-Delisle (formerly designated "Richmond Gulf"), which empties into the Hudson Bay.
The "Clearwater River" is located in Nunavik, in the west of the Labrador peninsula, in the administrative region of Nord-du-Québec, in Quebec, in Canada.
This river drains Clearwater Lake into Lac Guillaume-Delisle.
It flows west for about 70 km and empties into Lake Guillaume-Delisle.
This body of water, more properly a gulf, is connected to Hudson Bay on its west side via a narrow channel about 5 km long called "Le Goulet", meaning narrows or bottleneck.
