The Brenno is a 36 km long river in the canton of Ticino in Switzerland . It flows through the Blenio valley in a predominantly southerly direction and flows into Ticino at Biasca .
The main source river of the Brenno rises below the Piz Gaglianera in the Cogn dei Lavazz area . It flows through the valley portion Val Camadra takes at Campo the outflow of the lake Lago di Luzzone and joins in the basin of Olivone with the Lukmanierpass down flowing Brenno di Santa Maria .
In the lower reaches - between Malvaglia and the rockslide cone Buzza di Biasca - the Brenno is very overgrown. Its gravel deposits and those of its left tributaries Orino and Lesgiüna take up the entire width of the valley floor.
