The Limentra orientale (also: Limentra di Treppio) is a mountain river in Italy, a right tributary of the Reno. It rises from Monte la Croce in the Apennine Mountains. It enters the Metropolitan City of Bologna near Lentula and Treppio. Near Suviana a dam has been built on its course creating one of the largest reservoirs of the Apennines, with a capacity of about 43,850,000 cubic metres (1.549×109 cu ft). It flows into the Reno after 41 kilometres (25 mi), near Riola di Vergato.
