The weir measures 549 meters long. Retractable watergates makeup 144 meters of its length. They regulate the river’s flow, providing water for local farmers. Four small hydro plants create 50 GWh of electricity per year, enough power for 8,000 households.
Midway down the weir, feathery streaks rise into fins along its concrete towers. These represent a swan’s wings flying over the Nakdong River, a symbol that “envisions an eco-friendly future” and references the Ara Gaya (아라가야; map), a Gaya Confederacy (42~562 ACE) state that lived in this region.
The middle two towers hold stairs that lead down to observatories. Inside, find a Nakdong River lookout spot and information about the weir and its surroundings.
On the southwest banks sits a management center and cultural hall (창녕함안보통합관리센터; map). Open from 9 AM to 6 PM. It holds a variety of functions:
- First floor management offices.
- Second floor exhibition hall with displays of local culture and history.
- Second floor bike passport vending and certification.
- The Changnyeong Haman-bo Certification Center sits out front.
