The purpose of the Noordoewer/Vioolsdrift Dam (NVD) is to: increase the long-term sustainable yield of the Orange River System to replace the loss in yield due to upstream dam developments; provide for projected growth in water requirements; compensate for the impact of the Reserve implementation; provide re-regulation storage on the Lower Orange River for seasonal flow distribution.

Project Objectives:
- Increase the long-term sustainable yield of the Orange River System
- Replace yield loss from Lesotho Highlands Water Project Phase 2
- Support future large-scale irrigation developments in Namibia
- Compensate for environmental water requirement impacts
...

The project will enhance water security and support economic development in both Namibia and South Africa while ensuring sustainable river system management through appropriate water storage infrastructure.
