A whisper of history. A murmur of water. The La Deule. Right here before you flows a waterway steeped in centuries of activity.
From its source near Carency the La Deule has shaped the landscape of northern France. It’s a tributary of the Lys river itself a sub-tributary of the Scheldt. For centuries the La Deule has been a lifeline a commercial artery. Think of the countless barges that have plied its waters. They carried goods to and from Lille and beyond. Think of the bustling ports. The lifeblood of a thriving region.
The La Deule wasn’t always the calm canal you see today. In its upper reaches it retains some of its natural character. It was once known as the Souchez a wilder more unpredictable river. Its name itself hints at a darker past. It is said to derive from the Celtic word *Dubulā* meaning “the dark one”. An apt description for a waterway once choked with peat and shadowed by industrial pollution.
For centuries the people of Lille harnessed the La Deule’s power. They dug canals to connect the river to other waterways. They used its waters to power mills to irrigate fields. They even extracted peat a source of fuel and fertilizer. This peat was abundant. It was even found beneath Lille itself. However its use waned with the rise of cheaper coal from local mines.
The La Deule’s history is intertwined with that of Lille. In 1244 the city purchased its first section. Canals were gradually dug improving trade with the south and the sea to the north. Lille boasted two ports. The port of the Haute-Deule and the port of the Basse-Deule. The latter existed near what is now the Avenue du Peuple Belge. In 1751 a new canal the Moyenne-Deule was opened. It bypassed the citadel improving navigation. This canal was eventually replaced by a larger canal in 1978.
But the La Deule has not been without its challenges. Centuries of industrial activity left its sediments heavily polluted. Heavy metals such as lead zinc and thallium contaminated the water and soil. Even today the river’s ecological health is a concern. It’s among the most polluted waterways in France. The water quality is a complex issue. A significant cleanup is still required.
Yet despite its troubled past the La Deule is showing signs of recovery. Efforts to depollute the river and restore its natural environment are ongoing. Fish and other wildlife are returning. The La Deule is becoming a place for recreation. It’s a symbol of resilience a testament to nature’s ability to heal. It offers a green corridor for those who wish to explore. Take a walk. Take a bike ride. Discover the La Deule for yourself. Its story is far from over.
