Locals near the Kaligandaki river never call it Gandaki

As a guy who has been to The river many times, I've seen that the locals Never call The river Gandaki. For us, it's Kaligandaki (or Narayani if you're in Chitwan or Nawalpur) but it's never Gandaki. In fact, its closest name "Gandak" is used only after it reaches India.
