Acquafraggia

Acquafraggia (also Acqua Fraggia) is a short and frequently steep torrente, or seasonal stream, of the province of Sondrio in Lombardy, north Italy.

Its source is on Pizzo del Lago, at an elevation of , on the north side of the Val Bregaglia and close to the Swiss border which here marks the limit of the Po drainage basin. From here it flows in a southwesterly direction within the territory of the commune of Piuro until it joins the Mera as a right tributary at the locality of Borgonuovo, a little upstream from Chiavenna and the mouth of the Val Bregaglia.
