Most of Italy's rivers drain either into the Adriatic Sea (like Po, Piave, Adige, Brenta, Tagliamento, Reno) or into the Tyrrhenian (like Arno, Tiber and Volturno), though the waters from some border municipalities drain into the Black Sea through the basin of the Drava (Innichen and Sexten in Trentino-Alto Adige/Südtirol, Tarvisio in Friuli-Venezia-Giulia) or the Inn (Livigno in Lombardy), both tributaries of the Danube, and the waters from the Lago di Lei in Lombardy drain into the North Sea through the basin of the Rhine.
