The Ariège (Catalan: Arieja; Occitan: Arièja) is a river in the south of France. It is about 163 kilometers (101 miles) long. This river is a right tributary of the Garonne. This means it flows into the Garonne from the right side. The Ariège department is even named after this important river!

About the Ariège River

The Ariège river stretches for about 163.2 kilometers (101.4 miles). The area of land where all the water drains into the river is called its drainage basin. For the Ariège, this area covers about 4,135 square kilometers (1,597 square miles).

How Much Water Flows?

The amount of water flowing through a river is called its discharge. The Ariège river has an average yearly discharge of about 76.4 cubic meters per second (2,698 cubic feet per second). This measurement was taken at Pinsaguel, a town near where the Ariège joins the Garonne river. This average is based on data collected over 30 years.

This graph shows how the amount of water in the Ariège river changes throughout the year. You can see that May usually has the most water flowing, while September and August have the least. This is because of things like snowmelt in spring and less rain in summer.

Where the River Flows

The Ariège river begins high up in the Pyrenees mountains. Its source is in a lake called Lac de Font Nègre. This spot is right on the border between France and Andorra. It's near a place called Pas de la Casa in Andorra. The source is very high up, about 2,470 meters (8,100 feet) above sea level!

At first, the river flows north, marking the border between France and Andorra. Then, it turns towards the northeast.

The Ariège flows through a flat area called the Ariège plain. It then leaves the Ariège department and enters the Haute-Garonne department. Finally, it joins the Garonne river at a town called Portet-sur-Garonne. This is close to the big city of Toulouse.

The Ariège river passes through several important places:

The river flows through a total of 58 different towns or communes in France. It ends its journey by joining the Garonne river at Portet-sur-Garonne. This meeting point is about 140 meters (460 feet) above sea level.
