NamWater is set to discontinue releasing water for irrigation in the Hardap Irrigation Scheme if limited water inflow into the Hardap Dam persists.

In the wake of poor rainfall in its catchment area, the dam's water level stood at 12.8% on Tuesday.

Farmers at the Hardap Irrigation Scheme are worried about the critically low levels of the Hardap Dam due to poor rainfall in the area.

They say if the dry conditions continue, it may have an adverse impact on the irrigation scheme that relies on water for production.
