La Côte-de-Beaupré Regional County Municipality: in the municipality of Saint-Tite-des-Caps.
This small valley is mainly served by the route 138 which normally runs along the north shore of the St. Lawrence River; however, it distances itself from the river in this area of Charlevoix. Forestry is the main economic activity in this valley; second-hand tourist activities. The surface of the Lombrette River is generally frozen from the beginning of December until the end of March; however, safe traffic on the ice is generally from mid-December to mid-March. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
Geography
The Lombrette river has its source in Petite-Rivière-Saint-François at the mouth of an unidentified lake which is located between mountain at Liguori, Salvation Mountain and McLean Mountain. This small lake is located at:
south-west of the village center of Petite-Rivière-Saint-François;
east of a curve of the Sainte-Anne River.
From this source, the course of the Lombrette river descends with a drop of over parallel to the edge of the Laurentian plateau away from 4 to 5 km, depending on the following segments: Upper course of the Lombrette river
to the south, by forming a hook towards the east and down the mountain, to the outlet of a stream;
south down the mountain and passing on the west side of Salvation Mountain, to McLean stream ;
towards the south-east in a deep valley, until the mouth of a small lake which receives a stream ;
to the south in a valley between the McLeau Mountain and another mountain, collecting a stream and forming many small snakes in places, up to a stream ;
to the southwest by forming two S passing from the south side of a small hamlet, to route 138;
to the south, forming numerous small streamers, until the confluence of the rivière des Chenaux ;
southwards passing west of the hamlet Domaine-Armand-Crépeault west of the village of Saint-Tite-des-Caps, while winding in places, until the outlet of the black stream ;
south-west in agricultural area, to its mouth.
The Lombrette river flows on the east bank of the Sainte-Anne river, in Saint-Tite-des-Caps. This confluence is located west of the northwest shore of the St. Lawrence River and southwest of the center of the village of Saint-Tite-des-Caps. From the confluence of the Lombrette river, the current flows over generally south along the course of the Sainte-Anne River, to the northwest shore of the St. Lawrence river.
Toponymy
The map of the province of Quebec drawn up in 1870 by Eugène Taché indicates this watercourse in the form "R. The Ombrette”. This toponym would evoke the nickname of Pierre Simard, dit Lombrette, master mason who arrived in New France in 1654 and died between 1681 and 1686, and especially of his son, Noël Simard, dit Lombrette laborer. The latter obtained, in particular a concession at Cape Maillard in the vicinity of the Lombrette River. The nickname Lombrette, joined to the name of Pierre Simard or Cimar in the census of 1666–1667, still remains enigmatic. If it is not the name of a farm or a place known as the country of origin of Pierre Simard in the surroundings of Angoulême, if need be, the ombrette can be the diminutive of shade, a bony fish that is distinguished from salmon, trout and char by its small mouth. The graphic form L'Ombrette, adopted in 1949, was modified for that of Lombrette in 1974, by the Geographic Commission. The name "Rivière McLean" was also used in memory of John McLean, landowner at Saint-Tite-des-Caps. The toponym "rivière Lombrette" was formalized on August 29, 1972 at the Place Names Bank of the Commission de toponymie du Québec.
