The story behind it

The Nakdong drains a huge basin of green hills where farmers have grown rice for thousands of years. In summer the monsoon can dump enormous amounts of rain in a few days, and the water climbs over the fields until dykes and floodgates hold it back. Old towns such as Andong keep wooden houses and mask dances that belong to the river valley, and stone bridges cross the water where merchants once travelled. Near Busan the Nakdong slows down and spreads into a maze of sandbanks and reed beds. This estuary is one of the most important resting places for migrating birds in East Asia: swans, ducks and geese arrive every autumn from the cold north. Millions of people drink water from this river, so keeping it clean matters to the whole country.
