Dora Baltea
As it crosses the Aosta Valley, the Dora Baltea flows through the city of Aosta (where the Buthier, a small river, runs into it) and near all the main cities of the lower Aosta Valley: Châtillon, Saint-Vincent, Verrès and Pont-Saint-Martin. After it enters the Piedmont region, it passes through the city of Ivrea and a good part of Canavese, gets from its right hand the waters of the Chiusella and reaches the Po at Crescentino.
