Once forced to live with brackish water from Tam Giang Lagoon, Hue City built the Thao Long Dam to secure a source of fresh water for daily use and production. As a heritage city and a centrally governed city, Hue now hopes for a new Thao Long — not only to block saltwater and preserve freshwater, but also to create landscapes and open the way for sustainable waterway tourism.

Hue is blessed with a water system comprising many rivers and lagoons. Each river flows through a distinct land, carrying with it its own unique stories before merging into the Tam Giang Lagoon.
