And that day, unusually high water level rise, the river broke its banks and changed the direction of the current, rushing to the sea. Her new mouth was located 3 km South of the former, and access to the old channel was blocked by tons of mud and silt. The last stretch of the river Piave thus was deprived of regular access fresh water and filled only during high tides. Thus was born the Laguna del mort.
