Limpopo dams at critical levels as heavy rains trigger rising river flows and flooding
Limpopo is reeling from catastrophic floods that have damaged roads, schools, and health facilities, leaving nine dead and thousands displaced.

Heavy rains across Limpopo and Mpumalanga have pushed several dams to full or above-capacity levels, resulting in localised flooding and safety alerts.
The Department of Water and Sanitation (DWS) has confirmed that all major dams remain structurally sound; however, rivers and low-lying areas are currently experiencing high flows. Please remain cautious and stay informed of further updates.
Klaserie Dam is currently at 106.7%, and the Flag Boshielo Dam is at 105.6%. Spillover from upstream reservoirs is putting additional pressure on the Olifants River system.
Rising river levels have already resulted in flooding within the Mopani District and areas near Kruger National Park, necessitating the closure of several bridges and crossings.
'Despite extreme conditions, the Department’s real-time hydrological monitoring network has been central to providing real-time data, and more than seventy percent of stations remained operational, allowing officials to track rising river levels, monitor flood waves, and coordinate with disaster management teams in all affected areas and neighbouring countries through transboundary structures," DWS said.
'''Disaster centres remain active, unsafe crossings have been closed, and humanitarian assistance has been mobilised through disaster management structures. Residents are urged to avoid flooded roads, dam walls and spillways, and to be cautious of displaced wildlife.''
Below is the current status of dam levels:
Nsami Dam surged from 70% last week to 123% this week, spilling into downstream channels.
Modjadji Dam increased from 63% to 105% and is now operating above capacity.
Dap Naude Dam rose from 109% to 124%, reflecting extreme catchment response.
Middle Letaba Dam jumped from only 8% to 62%, a major recovery but still below full supply.
Nzhelele, Luphephe, Nwanedzi, Vondo, and Nandoni Dams all exceeded 105%, adding pressure to the Vhembe catchments.
Tzaneen and Ebenezer Dams remain above 100%, sustaining high flows into the Letaba River system. These sharp increases confirm the scale of inflows from persistent rainfall and explain the heightened flood risks downstream in Mopani and Vhembe districts.
Communities are urged to follow official warnings and evacuation instructions, avoid flooded roads and crossings, and remain alert to changing conditions. DWS reassures the public that its dam infrastructure is safe and continuous monitoring is underway to protect communities and downstream systems.
