Geography
The Impero rises near Monte Grande,[3] crosses the comunes of Aurigo, Borgomaro, Lucinasco, Chiusavecchia, Chiusanico and Pontedassio, giving its name to its valley, and ends in the Ligurian Sea in Oneglia (IM).
Impero basin (95 km2) is totally included in the Province of Imperia and also encompasses the communes of Cesio and Caravonica.[4]

Rio Trexenda
The Tresenda (or Trexenda) is the main tributary of the Impero; it rises with the name of rio Caravonica from monte Mucchio di Pietre and gets from its right bank Rio Bramoso and Rio Acquafredda. Its drainage basin is of 13.3 square kilometres.[5]
