Reference excerpt

The lac de la Belle Rivière is a freshwater body at the head of Belle Rivière on the watershed of lac Saint-Jean, in the unorganized territory of Belle-Rivière, in the Lac-Saint-Jean-Est Regional County Municipality, in the region Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada. Lake Belle Rivière is located in the northwestern part of the Laurentides Wildlife Reserve. This small valley is served by the route 169 and by the route des Laurentides which runs along the lake on the northeast side. A few secondary roads serve this area for the needs of forestry, recreational tourism activities. Forestry is the main economic activity in the sector; recreational tourism, second. The surface of Belle Rivière Lake is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally from mid-December to mid-March.

Geography The main watersheds adjacent to Lake Belle Rivière are:

north side: Bélair lake, Beauséjour lake, Curés lake, Belle Rivière, Vert Lake; east side: Thom stream, Sauce stream, Pikauba River, Bras des Angers, rivière aux Écorces; south side: Carpe lake, Paul stream, rivière du Milieu, Grand lac des Cèdres, Thom stream, Métabetchouane River. west side: Métabetchouane River, Belle Rivière stream, Grignon River, Ouiatchouan River, Lac Saint-Jean. The Belle Rivière lake has a length of 10.1 km (6.3 mi), a width of 1.4 km (0.87 mi) and an altitude of 346 m (1,135 ft). This lake has three parts formed by two narrows. This lake is mainly fed by the rivière du Milieu (coming from the south) and by the outlet (coming from the south) of the big lake of Cedars. The mouth of this lake is located to the west, at the Laurentian Highway bridge, at:

6.6 km (4.1 mi) south-east of route 169; 16.6 km (10.3 mi) east of the village center of Saint-André-du-Lac-Saint-Jean; 19.5 km (12.1 mi) south-east of lac Saint-Jean; 21.3 km (13.2 mi) south-east of the confluence of the Belle Rivière and a bay on the east shore of Lac Saint-Jean; 32.0 km (19.9 mi) south of downtown Alma; 33.0 km (20.5 mi) south-east of the entrance to the La Petite Décharge. From the mouth of Belle Rivière lake, the current follows the course of the Belle Rivière consecutively on 33.8 km (21.0 mi) northwesterly to the east shore of Lac Saint-Jean; from there, the current goes north on 15.4 km (9.6 mi) crossing this last lake, follows the course of the Saguenay river via the Petite Décharge on 172.3 km (107.1 mi) until Tadoussac where it merges with the Saint Lawrence estuary.

Toponymy The name "Belle Rivière" is linked to the river, a stream and the municipality of the same name in the same sector. The toponym Lac de la Belle Rivière was formalized on December 5, 1968, by the Commission de toponymie du Québec.

Worked examples

Example 1 — a first encounter with Lac de la Belle Rivière

Start with the simplest possible case. Write down what Lac de la Belle Rivière claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lac de la Belle Rivière before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lac de la Belle Rivière ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lac de la Belle Rivière

In research: Lac de la Belle Rivière appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lac de la Belle Rivière in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lac de la Belle Rivière is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lac-Saint-Jean-Est Regional County Municipality, Lakes of Saguenay–Lac-Saint-Jean, Laurentides Wildlife Reserve, so understanding it makes those chapters shorter.
In everyday life: Look for Lac de la Belle Rivière outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
