The mouth of "Lac aux Dorés" is located at the bottom of a bay south of the lake in Obalski Township.

On its irregular course, the river crosses successively 12 lakes: Ledden, David, Dulieux, Simon, Scott, Acinitchibastat, Gwillim, Chevrillon, Rush, Barlow, Opémisca and Michwacho.

On its route, the river drains in particular the area of establishment Cri de Oujé-Bougoumou, located on the north shore of Lake Opémisca.
