The Strona (pronounced as /it/) is a mountain torrent in the Province of Verbano Cusio Ossola, northern Italy, a tributary of the Toce. It rises from the small lake near Monte Capezzone at an elevation of 2100m (6,900feet)[1] and runs through the Valle Strona (the communes of Valstrona, Massiola, Quarna Sopra, Loreglia, Germagno, Omegna, Casale Corte Cerro and Gravellona Toce) before entering the Toce. At Omegna it is joined by the Nigoglia, the outlet of Lago d’Orta.
