With the exception of part of Liguria all of Northern Italy lies in the drainage basin of the Adriatic Sea (with rivers Po, Piave, Adige, Brenta, Tagliamento, Reno) though the waters from some border municipalities (Livigno in Lombardy, Innichen and Sexten in Trentino-Alto Adige/Südtirol) drain into the Black Sea through the basin of the Danube, and the waters from the Lago di Lei in Lombardy drain into the North Sea through the basin of the Rhine.
