The Rivière à l'Eau Claire flows through Nunavik in northern Quebec, draining toward Richmond Gulf in a landscape shaped by post-glacial drainage patterns. The river's name translates directly as "Clear Water," and it passes through or adjacent to Parc national Tursujuq. The full route is typically accessed beginning from Matagami, with the journey proceeding via Pourvoirie Mirage and Lac à l'Eau Claire before reaching Richmond Gulf.

The river is a multi-day wilderness canoe expedition. The route includes rapids and portages throughout, and paddlers have noted the chaotic, complex nature of the post-glacial drainage terrain. The whitewater character of the river is significant enough that at least one documented party spent a week at a canoe centre specifically for whitewater review before undertaking the trip. This is not a route suited to beginners or those without solid moving-water skills.

Canot Kayak Québec has produced a set of three digital maps covering the entire route, available through the Avenza Maps app at no cost. These maps indicate put-in and take-out points, rapids, portages, camping sites, and other points of interest along the river corridor. The maps were published in October 2022 and cover the Nord-du-Québec region.

Given its location deep in Nunavik, the river is a remote expedition-style destination with no nearby urban infrastructure. Paddlers should plan for full self-sufficiency. The region's subarctic setting means the paddling season is short, concentrated in the summer months when ice-free conditions prevail.
