The Lemme is a river 35 km torrent, a right tributary of the Orba, which flows through the Province of Alessandria in northern Italy.
Geography
[edit | edit source]Its source is near Monte Calvo; from there it passes through the communes of Fraconalto, Voltaggio, Carrosio, Gavi, San Cristoforo, Francavilla Bisio, Basaluzzo and finally Predosa where it enters the Orba.
Main tributaries
[edit | edit source]left hand tributaries
[edit | edit source]- rio delle Acque Striate;
- rio Morsone: it starts near Monte Tobbio and meets the Lemme in Voltaggio;
- rio Ardana: its upper valley includes Bosio, from which flows northwards meeting the Lemme in Gavi;
- rio Riolo: from San Cristoforo it runs not faraway from the Lemme meeting it near its confluence with the Orba.[3]
right hand tributaries
[edit | edit source]- rio Carbonasca: from Fraconalto goes till Voltaggio where it meets the Lemme;
- torrente Neirone:
- torrente Riasco: it collects the waters flowing in the area of Pasturana and Tassarolo and meets the Lemme near Francavilla Bisio.[3]
Floods
[edit | edit source]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 | edit source]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]
