Lake Kariba water levels begin to rise

Staff Reporter

Water levels at Lake Kariba are steadily increasing, reaching 475.87 meters above sea level, equivalent to 2.61% of usable storage, as of January 6, 2025.

The Zambezi River Authority (ZRA), which manages the reservoir, attributed the rise to “sustained rainfall over the reservoir and its immediate catchment area.”

In a statement yesterday, the ZRA noted, “While the water levels remain below those recorded on the same date last year at 477.28 meters (12.32% usable storage), this increase offers a glimmer of hope for improved water security.”

The authority further emphasized the importance of continued rainfall to ensure a meaningful rise in usable storage.

“This positive development highlights the potential for improved inflows during the rainy season, which is critical for supporting power generation and other economic activities,” the ZRA added.

Energy analysts have welcomed the development, noting its significance for the power sector.

Engineer Tafadzwa Chigwada described the increase as a crucial step toward stabilizing electricity supply in Zimbabwe and Zambia.

 “A steady rise in water levels will allow the Kariba Hydroelectric Plant to operate at improved capacity, reducing reliance on costly thermal power and imports,” he added

Beyond the energy sector, the rising water levels could also boost irrigation activities, support fisheries, and improve tourism prospects in the region.

Tourism operator Fungai Madziwa said, “A fuller Kariba not only attracts visitors but also restores aquatic ecosystems vital to fishing communities. It’s a win-win for both livelihoods and the environment.”

However, experts cautioned that sustained rainfall would be critical to ensure meaningful gains in water storage.

 “This is an encouraging start to the year, but we must remain vigilant as Lake Kariba’s capacity depends on consistent inflows and efficient water management,” said hydrologist Dr. Ruvimbo Dube.

Electricity generation at Lake Kariba has been severely constrained in the past due to critically low water levels, prompting widespread power outages in both countries.

Zimbabwe, in particular, has had to contend with rolling blackouts lasting up to 18 hours daily. The anticipated improvement in storage levels could mitigate these challenges and support economic recovery efforts.

Meanwhile, Lake Kariba, one of the largest man-made reservoirs in the world, plays a vital role in energy and water security for both Zimbabwe and Zambia. With the rainy season still ongoing, stakeholders remain hopeful that the upward trend in water levels will continue, bringing relief to millions who depend on the reservoir for energy, agriculture, and livelihoods.
