The Rivière à Grignon (which means Grignon's River in English) is a river in Quebec, Canada. It flows into Lac Saint-Jean. The river is located in the municipality of Chambord. This area is part of the Le Domaine-du-Roy Regional County Municipality.
The river valley has different uses. The upper part is mostly covered by forests. Forest roads help people get around there. The lower part of the valley is used for farming. Main roads like Route 169 also run near the river.
During winter, the Grignon river usually freezes. This happens from early December to late March. However, it's generally safe to walk on the ice from mid-December to mid-March.

River's Journey: Where it Starts and Flows
The Grignon river begins in a lake that doesn't have a name. This lake is shaped a bit like a birch leaf. It is about 1.2 km (0.75 mi) long and sits at an altitude of 284 m (932 ft).
The lake's outlet is located:
- About 16.6 km (10.3 mi) southeast of Roberval.
- About 7.3 km (4.5 mi) southwest of Chambord village.
- About 7.3 km (4.5 mi) south of where the Grignon river ends.
From its start, the Grignon river flows for about 12.4 km (7.7 mi). It drops about 183 m (600 ft) in height along the way.
How the River Flows
The river's journey can be divided into several parts:
- It flows about 1.6 km (0.99 mi) northwest first. It passes an outlet from another lake.
- Then, it flows about 2.4 km (1.5 mi) east. It crosses Lake Delaunaire, which is 1.8 km (1.1 mi) long.
- Next, it makes a big turn, flowing about 6.5 km (4.0 mi) east, then northeast. It gets close to a railway line.
- Finally, it flows about 1.9 km (1.2 mi) north through farmland. It crosses Route 169 and the railway. It also collects water from another small stream before reaching its end.
Where the River Ends
The Grignon river empties into the Anse de Chambord. This is a bay on the southwest shore of Lac Saint-Jean.
The river's mouth is located:
- About 3.9 km (2.4 mi) southeast of Pointe-Chambord.
- About 3.8 km (2.4 mi) west of the center of Chambord village.
- About 11.6 km (7.2 mi) southeast of downtown Roberval.
After joining Lac Saint-Jean, the water travels east for about 33 km (21 mi). Then, it flows into the Saguenay River for about 172.3 km (107.1 mi) east. The Saguenay River eventually reaches Tadoussac and joins the Estuary of Saint Lawrence.
River's Name: What "Grignon" Means
The word "Grignon" is a family name that comes from France. The name "Rivière à Grignon" was officially recognized on September 5, 1985. This was done by the Commission de toponymie du Québec, which is like a naming committee for places in Quebec.
