[1] The name of the river, Rivière Gravel, was made official by the Commission de toponymie du Québec on 25 February 1976.

[3] The Gravel is one of the main tributaries of the Aux Rochers River, the others being the MacDonald, Pasteur and Schmon.

[5] During deglaciation the ice in the Schmon and Gravel river valleys was probably slow to melt, then poured their water into Lake Walker.

[7] Within the proposed park, the river's valley flows north northeast-south southwest for about 12 km (7.5 mi) before entering Lake Walker.

[8] A map of the Ecological regions of Quebec shows the river rising and flowing south through the eastern spruce/moss domain of the boreal zone.
