Bogna (river)
River in Italy
The Bogna is an Alpine torrent of the Ossola in northern Italy. It flows through the Val Bognanco and into the river Toce near the city of Domodossola as a right tributary. The river starts at Monte Bardo, has a length of about 12 miles, and is known as an "unjust river" for the destructive floods it has caused in Domodossola for centuries.
