  • rio Morsone: it starts near Monte Tobbio and meets the Lemme in Voltaggio;

Floods

[edit]

The Lemme is characterised by an extremely variable discharge; very little water flows during the summer months, but it can also give rise to significant floods, such as those of 1978.

History

[edit]

The Département du Lemo or Dipartimento del Lemo of Ligurian Republic took its name at the end of the 18th century from the stream.[4]
