The lower part of this valley is mainly served by the route 381 (boulevard de Monseigneur-De Laval) which goes up the course of the Rivière du Gouffre by the west bank.

The water level of the river varies with the seasons and the precipitation; the spring flood generally occurs in April.

Some researchers, notably Nérée Tremblay, author of St-Pierre and St-Paul de la Baie St-Paul (p. 269), the name evokes the memory of Pierre Rémy (Paris, 1636 - Montreal, 1726), a Sulpician who arrived in New -France in 1672 and first priest to receive ordination in Montreal from the hands of Mgr Laval in 1676.

Several generations of a Fortin family, millers from father to son, continue to operate this mill for more a century and a half.
