Pyasachnik Reservoir, reservoir in Bulgaria

Pyasachnik Reservoir is a large body of water in the Gornotrakian Plain of northwestern Bulgaria, located about 35 kilometers from Plovdiv. The reservoir covers approximately 9 square kilometers and can hold over 200 million cubic meters of water, situated between the villages of Belovitsa and Lyuben.

Pyasachnik Reservoir was constructed between 1958 and 1964 on the upper course of the Pyasachnik, a left tributary of the Maritsa. Its water is used to irrigate about 270 km² of arable land in the Upper Thracian Plain.

The reservoir lies northwest of Lyuben in Plovdiv Province, reached by local roads through the villages of Belovitsa and Lyuben. Its banks are open farmland, so access points are informal and unmarked; anglers should ask locally before settling on a spot. The reservoir is fed by the Pyasachnik river and used for irrigation, so water levels vary through the year.

In 2009 a world record was set at the reservoir when a white amur weighing nearly 40 kilograms was caught by a fisherman. This achievement drew the attention of anglers from around the world to the waters.
