Lake Garda   The major Italian lakes are located in the pre-alpine belt and in the Apennine area between Umbria and Lazio, the only exception being the two Apulian coastal lakes of Lesina and Varano, both with brackish waters.

   Lake Garda is one of the largest as regards the basins of central Europe, but it is beyond the twentieth position considering the entire continent; in fact in northern Europe there are much larger lakes.

   The northern lakes are almost all of glacial and fluvial origin, while in the center there are also basins of volcanic origin, such as the three Lazio lakes present in the table.
