Sorabora Wewa

Sorabora Wewa (Sinhalese: සොරබොර වැව) is an ancient reservoir in Mahiyangana, Badulla District Sri Lanka.

[2] The tank was built by damming the Diyawanna Oya with a 485-meter embankment.

[3] It does not make use of the structure called Bisokotuwa, which helps to regulate water pressure at the sluice gates from inside the tank and protect the embankment from erosion.

[4] It is said that this is the only such type sluice gate found in Sri Lanka.
