ZRA, jointly run by Zimbabwe and Zambia, said the 42 billion cubic metres (BCM) allocated to power utilities from both countries on June 25 will remain for the rest of the year.

Before the upward review, Zesco Limited (Zambia) and the Zimbabwe Power Company, were sharing an allocation of 30 BCM equally.

“The 12 million cubic meters (BCM) increase in water allocation announced on 25th June 2021 shared equally between the two power utilities, Zesco Limited and the Zimbabwe Power Company, for their respective power generation at Kariba North Bank Power Station and Kariba South Bank Power Station will be sustained for the rest of the year 2021,” ZRA chief executive officer Edward Kabwe said.

“The increase has now pushed the 2021 water for power generation allocated to the power utilities at Kariba stations from 30 BCM to 42 BCM.”

ZRA said the allocations were being increased despite the fact that Kariba Dam levels were receding.

The dam levels start going down at this time of the year after the end of the rainfall season. On August 9, Kariba Dam levels were pegged at 482.05m.

” From the last update made on 7th June when the lake level was 482.82, the lake level has receded by 0.77m,” Kabwe said.

“This has placed the lake level at 6.55 meters above the minimum operating level (MOL) of 475.50m.

“The recorded lake level of 9th August 2021 translates to 30.66 billion cubic meters (BCM) or 47.32% of usable or live storage.

“Last year on the same date, the Lake level was lower at 480.94m with 25.18 BCM or 38.86% of usable storage, with the lake being only 5.44m above the minimum operating level.”

On Monday, Zimbabwe was generating 1 023 megawatts of electricity from Kariba Dam, according to ZPC.

Meanwhile, Zambezi River flows around Victoria Falls are also receding following the end of the 2020/21 rainfall season.

“The Zambezi River flows at the world tourist destination, the Victoria Falls, are also receding owing to the close of the 2020/2021 rainfall season, closing the period under review at 627 m3/s recorded on 9th August 2021 which is less than the 9th August 2020 reading of 678 m3/s,” Kabwe said.

” It should be noted that, although the flows observed in the main-stream Zambezi River at both Chavuma and Victoria Falls gauging stations are generally lower this year than last year, inflows into Lake Kariba from its immediate environs (Lower Catchment) were higher this year than last year, which, to a large extent, explains why the lake posted higher levels this year than last year.

“Further, the water management strategies employed by the Authority to maintain sustainable storage through the water allocation system at Kariba are clearly paying off.”

Reduced flows are expected to persist until the start of the 2021/22 rainfall season.

Flooding risk rises in Zimbabwe, Southern Africa as heavy rains forecast

Published

on

Flooding is expected to intensify across parts of Southern Africa, including Zimbabwe, as heavy rainfall continues to affect the region, according to the latest weather hazards update from the Famine Early Warning Systems Network (FEWS NET).

In its Global Weather Hazards Summary for March 12–18, FEWS NET said moderate to locally heavy rainfall has been observed across several countries in the region, raising concerns about flooding in vulnerable areas.

The agency said the rainfall has affected western, central and eastern parts of Southern Africa, including Angola, Zambia, Malawi, central Mozambique, northern Madagascar, Botswana, Namibia, South Africa and Zimbabwe.

“During the past week, moderate to locally heavy rainfall was observed over northern, central and eastern Southern Africa,” FEWS NET said in the report.

The agency noted that flooding has already been recorded in some parts of the region, including Cunene Province in southern Angola and Rundu in northern Namibia, as rainfall continued across several countries.

Over the past 30 days, cumulative rainfall has been above average across southeastern Angola, northeastern Botswana, central South Africa, Lesotho, central and southern Zimbabwe and parts of Malawi and Mozambique, increasing the likelihood of flooding in low-lying and flood-prone areas.

FEWS NET warned that the situation could worsen in the coming days.

“(This week) , heavy rainfall is predicted over northern and eastern Zambia, including central and northern Angola, central and eastern Zambia, Malawi, northern and eastern Zimbabwe, Mozambique, northeastern South Africa, Eswatini and northern Madagascar,” the report said.

According to the outlook, the forecast rainfall raises the risk of flooding in many local areas across the region, particularly where soils are already saturated following weeks of above-average rainfall.

The weather monitoring agency also noted that hot conditions are likely in western Angola and southwestern Madagascar, even as other areas brace for continued heavy rains.

FEWS NET provides climate and food security early warning information to support humanitarian planning and disaster preparedness across vulnerable regions.

Parliament debates disputed chiefdoms across the country

Published

BY STAFF REPORTER 

Parliament has raised concern over increasing disputes over traditional leadership, with lawmakers warning that contested chiefdoms are undermining governance and development in rural communities.

Moving a motion in the National Assembly, Hwange West MP, Vusumuzi Moyo said the growing number of chieftainship disputes posed a threat to peace and cultural heritage.

“I rise today to debate on a matter which I believe is a matter of national importance, the growing prevalence of disputed chiefdoms across Zimbabwe and the serious threat that these poses to peace, governance, development, and the preservation of our cultural heritage,” Moyo told Parliament. 

He said many disputes date back to distortions created during the colonial period.

“Some of these disputes… emanate from colonial times… when the colonial masters moved in. When they moved in, we already had governing structures,” he said. 

Moyo also referenced communities in Hwange District, saying colonial relocations disrupted traditional governance systems.

“I remember in the constituency that I come from, most of these people… had been resettled from far-off lands, fertile lands, and dumped in Hwange District,” he said. 

He warned that unresolved leadership disputes weaken governance at grassroots level.

“Madam Speaker, when a chiefdom becomes disputed, those constitutional functions grind to a halt. Customary courts lose legitimacy. Land allocations become contested. Development programmes stall,” he said. 

Moyo urged Government to establish clearer succession procedures for traditional leaders.

“It is my sincere hope that… we could start the conversation of trying to restore our culture by providing the necessary legislation to make sure that we cure all this,” he said.

Rising Zambezi flows lift Kariba water levels amid improved rains

Published

on

BY WANDILE TSHUMA

Water levels at the Kariba Dam are gradually rising following improved rainfall across the Zambezi River Basin, bringing cautious optimism for water availability and power generation.

In a hydrological update released Tuesday, the Zambezi River Authority said the Lake Kariba reservoir level had reached 477.74 metres above sea level as of 10 March 2026.

Usable live storage now stands at 15.57 percent, equivalent to about 10.08 billion cubic metres of usable water.

The Authority said the increase is being driven by improved rainfall across much of the Kariba catchment during the 2025/2026 rainy season, which has boosted river flows and inflows into the reservoir.

“This reflects an improvement compared to the same date in 2025, when the reservoir stood at 476.93 metres above sea level with usable live storage of 9.87 percent,” the Authority said.

Zambezi flows rising at key monitoring points

River flows are also increasing at key monitoring stations along the Zambezi River.

At the Chavuma Gauging Station, flows reached 3,058 cubic metres per second on 10 March 2026, significantly higher than 2,088 cubic metres per second recorded during the same period last year.

Flows have also risen sharply near Victoria Falls, a key tourism and hydrological monitoring point.

At the Victoria Falls (Nana’s Farm) Gauging Station, river flows increased to 1,645 cubic metres per second, compared to 871 cubic metres per second on the same date in 2025.

The Authority said the upward trend reflects stronger rainfall upstream and around the Victoria Falls area, which is feeding the Zambezi system.

Outlook

The Zambezi River Authority said it will continue monitoring rainfall patterns and inflows across the basin to guide water utilisation at hydropower stations linked to the Kariba Dam.

The reservoir is a critical source of electricity for both Zimbabwe and Zambia, which jointly own and manage the dam through the Authority.
