Erdre

The Erdre is a 97.4 km (60.5 mi) long river in western France, right tributary to the Loire. Its source is in the Maine-et-Loire department, near La Pouëze. It flows through the departments Maine-et-Loire and Loire-Atlantique. The Erdre meets the Loire in the city of Nantes. Other towns on the Erdre, going downstream, are Candé, Riaillé, Nort-sur-Erdre and Sucé-sur-Erdre. South of Nort-sur-Erdre, the river flows through reclaimed marshland, and is up to a kilometer wide at the Plaine de Mazerolles near Sucé-sur-Erdre. At the Plaine de la Poupiniere, the Nantes-Brest canal joins the Erdre. The Erdre flows into the Loire via the St Felix canal tunnel under Rue Henri IV, emerging near the main railway station.
