The route 400, connecting the Gouin Dam to the village of Parent, Quebec, serves the valley of "De La Galette River" bypassing the north-west Louis-Georges-Morin (altitude: 535 metres (1,755 ft)); this road also serves the peninsula which stretches north in the Gouin Reservoir on 30.1 kilometres (18.7 mi).

The surface of the "De La Galette River" is usually frozen from mid-November to the end of April, however, safe ice circulation is generally from early December to late March.

The "Galette River" originates at the mouth of the unidentified lake (length: 2.2 kilometres (1.4 mi) altitude: 449 metres (1,473 ft)).

In the past, in French Canada, the term "galette" meant a kind of flat biscuit or crepe cooked in the pan.

In the twenty-first century, Québec toponymy has a dozen or so entities called "Galette", mostly lakes.
