context_page_description: The Cervo is a 65-kilometre torrent in the Piedmont region of north-west Italy. It is the principal tributary of the river Sesia, which itself is a significant tributary of the Po.
context_section_description: It crosses the provinces of  Biella (communes of Piedicavallo, Rosazza, Campiglia Cervo, Sagliano Micca, Andorno Micca, Tollegno, Biella, Candelo and Castelletto Cervo) and Vercelli (Quinto Vercellese).
  The Cervo’s source is the Lago della Vecchia (close to the Rifugio della Vecchia) in the Biellese Prealps. From the Lago della Vecchia it flows rapidly through a large number of communes of the Valle del Cervo. Close to Tollegno it receives the torrent Oropa from the right then crosses the eastern part of the city of Biella, in particular the quarter of Chiavazza.
  From here the valley widens and the torrent flows more slowly along a broad and pebbly stream bed. In this section of its course the Cervo is united with a number of modest tributaries: the Mologna, the Chiebbia, the Lu Rialet and the Bruma. Near the town of Cossato the flow grows visibly when the torrent is joined from the left by the Strona di Mosso. Near Castelletto Cervo it receives the waters of the Ostola and enters the plain of the province of Vercelli.
  In the Vercellese plain, where the Canale Cavour crosses over the torrent, the Cervo is significantly enriched by the contribution of numerous minor water courses and canals. In the area of Collobiano it is joined by more important torrents: the Rovasenda and Marchiazza from the left and from the right the Elvo, its most important tributary.
  At this point the Cervo turns from a torrent into a river which can be expected to flow continuously throughout the year. It advances lazily towards the Sesia which it joins near Quinto Vercellese as its most important tributary.
