The Ministry of Natural Resources and Energy has issued an advisory following heavy rains between December 30, 2024, and January 6, 2025, which have significantly impacted the country’s water systems.
he rainfall, particularly on January 2, has boosted dam capacities and river flows across the nation, signaling both opportunities and risks.
After a period of concerningly low water levels due to high temperatures in late 2024, the recent rainfall has led to notable improvements.

The Hawane Dam, for instance, saw its capacity rise from 39.02% in December to 48.75% as of January 6, 2025.
Additional rains and anticipated water releases from transboundary dams in South Africa are expected to further bolster dam levels.
However, the Ministry has cautioned the public about potential flooding risks, particularly along the Mkhondvo River, due to increased rainfall in South Africa and potential water releases from shared dams.
River flows have surged dramatically in recent days. The Great Usuthu River, previously flowing at less than 2 m³/s, has reached 38.06 m³/s, while the Mkhondvo and Lusushwana rivers have recorded flows of 37.86 m³/s and 16.15 m³/s, respectively.
This sharp increase poses a flood risk in vulnerable areas such as Mahamba, Sidvokodvo, and Mankayane, particularly where the Mkhondvo and Usuthu rivers converge.
The Ministry warns that the combination of heavy rainfall, transboundary dam releases, and elevated river levels could lead to further complications.

Communities along the Ngwempisi River, which feeds into the Usuthu River, are also advised to remain on high alert.
Residents in flood-prone areas are urged to stay vigilant, monitor official updates, and take necessary precautions to protect their families and properties.
While the rising water levels bring hope for improved water storage, preparedness remains key to mitigating potential risks.
