The Labūnava Reservoir is an artificial lake in Kėdainiai District Municipality, in central Lithuania. It is located south from Kėdainiai, next to Labūnava village. It was created in 1977, when a dam on the Barupė river was built next to Labūnava village. In 2003, the dam was reconstructed and a small hydroelectric plant (of 160 kW) built. The banks of the reservoir are curvy, often overgrown by reed beds. The reservoir is mostly surrounded by agriculture lands, but a small section of the Labūnava Forest is located nearby. The reservoir water is used for irrigation.
