The Kariba Lake, a critical water body for hydropower generation in Zambia and Zimbabwe, has shown a steady rise in its water levels due to sustained rainfall in the reservoir and its immediate catchment area.
According to the Zambezi River Authority (ZRA), the lake is designed to operate optimally between levels of 475.50m and 488.50m, with a 0.70m freeboard. As of January 6, 2025, the lake level was recorded at 475.87m, representing 2.61% usable storage. This marks a decrease from the 477.28m level (12.32% usable storage) recorded on the same date last year.
Monitoring Period: December 24, 2024 – January 6, 2025
During the monitoring period, rainfall in the region contributed significantly to the increase in water levels. While the current usable storage remains low compared to the same period in 2024, the upward trend provides a glimmer of hope for improved water availability for hydropower generation.
Importance of Kariba Lake for Hydropower
Kariba Lake plays a vital role in electricity generation for both Zambia and Zimbabwe. Maintaining water levels within the operational range is crucial to ensuring consistent hydropower output, which supports national grids and drives economic activities.
The Zambezi River Authority continues to monitor the lake levels closely, providing updates on hydrological conditions to stakeholders.
Although the Kariba Lake level is still below last year’s figures, the recent rainfall and gradual increase in usable storage indicate positive prospects for the months ahead. Continued monitoring and sustainable water management will be key to ensuring the lake’s reliability as a source of energy for the region.
