About Kala Wewa

Kala Wewa is ancient hydraulic engineering at its most audacious: a reservoir built by King Dhatusena around 460 AD, its embankment stretching over six kilometres to impound (with its twin Balalu Wewa) some seven square miles of water for the dry-zone kingdom. Its masterpiece flows out of sight: the Yoda Ela or Jaya Ganga, the 87-kilometre canal carrying Kala Wewa's water to Anuradhapura's tanks on a gradient astonishing even to modern engineers - roughly one foot of fall per mile for its first seventeen miles, a precision achieved fifteen centuries before laser levels. The chronicles' price was terrible: Dhatusena, showing his treasury to his usurping son, gestured at the tank and said 'this is all the wealth I possess' - and was walled up alive for it. The colossal Avukana Buddha gazes over the water he impounded; sunset on the bund, fishermen poling home, closes the story gently.
