Savio (river)
In Montecoronaro, a frazione (an Italian subdivision of a municipality) of Verghereto, the river takes the name of Savio. The river flows through the communes of Bagno di Romagna and San Piero in Bagno and, after a few kilometres, it forms an artificial reservoir, the Lago di Quarto, where it is joined, on the right side, by its first important tributary, the stream Para.
