LAKE Tugwi-Mukosi has risen to 99.6 percent full following sustained rainfall in its catchment area, raising the possibility it could start spilling any time soon if current inflows continue, the Zimbabwe National Water Authority has said.
In an update issued on Monday, ZINWA said the water level in the country’s largest inland dam had reached 99.6 percent as of the close of day yesterday, driven by significant inflows resulting from ongoing rains across the catchment.
“Tugwi-Mukosi is experiencing very high inflows due to ongoing rainfall in its catchment area,” said ZINWA in a statement.
“As of today, December 30, 2025, the lake level has risen to 99.6 percent, and the dam may fill and spill at any time if inflows continue.”
The authority advised communities downstream of the dam to remain alert, warning that a spill could occur should the rains persist at their current intensity.
Lake Tugwi-Mukosi, located in Masvingo Province, is a strategic national water body designed for irrigation, hydro-electric power generation, fisheries development and flood control.
Its catchment covers parts of Masvingo, Midlands and Matabeleland South provinces, areas that have been receiving steady to heavy rainfall since the onset of the 2025/2026 rainy season.
The current rain season has been characterised by widespread and consistent precipitation across much of the country, following a delayed but strong start in December.
The Meteorological Services Department has reported above-normal rainfall in several regions, with some areas experiencing prolonged downpours that have led to rising river levels, waterlogged soils and increased inflows into major dams.
Several other dams across the country have also recorded rising water levels as a result of the improved rainfall outlook, a sharp contrast to previous seasons.
While the increased rainfall has boosted water security prospects for irrigation, urban supply and power generation, authorities have cautioned that it also heightens the risk of flooding in low-lying areas and downstream communities, particularly where dams approach full capacity.
ZINWA said it would continue to monitor inflows at Tugwi-Mukosi and provide updates as the situation develops, urging residents downstream to stay informed and heed any safety advisories.
