The hydrological service has warned that the level of the lower Orange River is expected to rise because of heavy rainfall and dam releases in the upper catchment in South Africa.
Adding to this is the flow from the Fish River as a result of rainfall and dam releases (Naute Dam) in the Orange-Fish catchment.
“Water users must be on alert for possible flooding and take the necessary precautionary measures,” the service said.
