Dora Baltea

Dora Baltea or Doire Baltée ( or Duria Bautica; Valdôtain dialect: Djouire; Piemontes: Deura Bàotia), is a river in northern Italy. It is a left-hand tributary of the Po River, and is about  long.

 Geography 
Dora Baltea is formed on the Mont Blanc massif by the confluence, near Entrèves, of two small rivers: Dora di Ferret, that comes from the Pré de Bar Glacier in Val Ferret; and Dora di Veny, that comes from the Miage Glacier in Val Veny.

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.

The watershed has an area of , and its discharge (volume of water which passes through a section of the river per unit of time) is 96 cubic metres per second when it gets to the Po river.
