The Tirljan Dam ( Russian Плотина Тирлянского водохранилища ) is a dam in the republic of Bashkortostan (Bashkiria), Belorezk district in the southern Urals in Russia . On August 7, 1994 , the dam broke, which led to a tidal wave in four neighboring villages, including the district center of Belorezk .
The dam was an earthfill dam about 10 m high and was built before 1917 near the village of Tirljanski . The dammed Tirljan River, after which the dam was named, is a tributary of the Belaya . In this karst limestone landscape, droughts alternate with heavy, unpredictable rainfall in a short time. The dam was relatively small with a height of 10 m; the reservoir contained 8.6 million m³ of water.
During a heavy rain that lasted from August 5th to 8th, the dam was flooded and washed away. The segment weir locks that did not work and therefore could not be opened were directly responsible for the break .
Tirljanski, Shushpa, Kataika and Belorezk were affected by the tidal wave. There were 29 deaths, 786 homeless and property damage amounting to 52.3 billion rubles (the equivalent of around 22.8 million US dollars at the time ).
