History and some facts

The river's name was first mentioned in 834 AD, the former municipality

Jona was named much later. It is assumed that the name originates as either Celtic Jauna (the cold one) – the Jona is still largely determined by forest area – or, as Indo-European yamam, meaning stream. Latest interpretations say that the Indo-European word jeu roughly means to move, followed by the Old High German name Jouna .^[2]
