Râul Doamnei

Râul Doamnei is a left tributary of the river Argeș in Romania. Its source is on the eastern slope of Moldoveanu Peak (Făgăraș Mountains), the highest mountain peak in Romania. It discharges into the Argeș just north of Pitești. Its upper course, upstream from the confluence with the Zârna, is also called Valea Rea. Its length is 107 km (66 mi) and its basin size is 1,836 km² (709 sq mi). It frequently dries up in summer, owing to the works upstream that have redirected part of its water supply toward a reservoir serving the hydroelectric plant on the Argeș.

Râul Doamnei flows through a hilly region, forming narrow strips of fertile plain on both of its banks. The following towns and villages are situated along the river Râul Doamnei, from source to mouth: Slatina, Sboghițești, Corbi, Domnești, Pietroșani, Coșești, Dârmănești, Purcăreni, Colibași and Ștefănești.
