Budha Dariya: From a river to a drain of toxic water
It is a tradition in the Punjabi language to call old courses or tributaries of rivers, Budha(Old) or Purana(Ancient). An old course of river Ravi was called Budha Dariya. A tributary that originated from the Satluj bay near Ropar town is also called Budha or Purana Dariya. This tributary fell into Ghaggar river near Moonak(Patiala district), but then it started flowing parallel to the Ghaghar.
