HARARE – Zimbabwe National Water Authority (ZINWA) has issued a fresh public advisory after sustained rainfall filled major reservoirs, with Tugwi‑Mukosi Dam now spilling over and downstream flows rising sharply.
The warning comes amid unusually heavy rains that have pushed the country’s key dams, including Mutirikwi and Manjirenji, to full capacity, prompting controlled releases to manage inflows and protect dam safety. Authorities say communities along the lower reaches of the Tugwi and Runde rivers should remain alert and exercise extreme caution.
Tugwi‑Mukosi Spill: A Rare But Not Unprecedented Event
Tugwi‑Mukosi, also known as Tokwe‑Mukosi Dam, is the largest inland reservoir in Zimbabwe, built to store up to 1.75 billion cubic metres of water for irrigation, flood control and power generation. The dam was constructed over nearly two decades and commissioned in 2017, and has only reached spill level a handful of times, its first historic overflow occurred in 2021, marking a milestone for the Lowveld’s irrigation potential but also raising downstream flood concerns.
That 2021 spill, while celebrated for boosting water security and irrigation prospects, also forced heightened caution among communities below the spillway as the combined Tugwi and Mukosi river flows surged into the Runde River system.
The Tokwe-Mukosi Dam disaster of February 2014 remains one of Zimbabwe’s worst flood emergencies. Heavy rains overfilled the dam, forcing urgent water releases that inundated downstream villages. Thousands were displaced, crops destroyed, and infrastructure damaged. The crisis exposed gaps in early warning systems and dam management, highlighting the need for vigilance and careful planning during extreme rainfall events to protect communities.
Rainfall and Current Weather Patterns
This year’s heavy rains have been widespread across Zimbabwe, with meteorologists noting above‑average precipitation across key catchments. National dam levels have climbed significantly compared with last year, with reports confirming that several major dams are at or near full capacity after strong inflows.
While conditions can vary locally, the continued wet spell, driven by seasonal rain bands, has increased the risk of flooding in low‑lying districts, particularly in Masvingo and neighboring provinces downstream of the dam systems. Authorities urge people to monitor weather updates closely and adhere to safety guidance.
Public Safety and Precautions
ZINWA’s advisory calls for residents to avoid crossing flooded rivers and low‑lying bridges, especially during peak flows. Families are urged to supervise children and keep them away from riverbanks. Local leaders and emergency services have been asked to step up awareness campaigns and support vulnerable communities.
