The Strėva (German: Strebe) is a river in Trakai and Kaunas district municipalities, Lithuania. In 1348, the Battle of Strėva between the Grand Duchy of Lithuania and the Teutonic Knights was fought on the frozen river. In 1962, the river was impounded to create the Elektrėnai Reservoir, the third-largest artificial lake in Lithuania. The Strėva flows through Elektrėnai, Žiežmariai, Semeliškės. A 2001 study found the Strėva to be one of the cleanest rivers in the Neman basin in Lithuania.[1]
