⚠️ 5-DAY FLOOD FORECAST (VOLTA BASIN) | 25–29 AUGUST 2026

The latest forcasts from the VOLTALARM system shows rising river flows at Yarugu and Pwalugu on the White Volta, and Nangodi on the Red Volta, over the next five days.

SONABEL is expected to commence spillage of the Bagre Dam from Friday, 28 August. This may further increase river flows downstream and heighten the risk of flooding.

Residents in vulnerable areas, particularly Sapeliga, Bazua, and communities in the Talensi and Nabdam Districts, are urged to remain vigilant and take the necessary precautionary measures.

Slight rises in river levels are also expected at Lawra, Bui and Bamboi, but flooding is not anticipated at these locations during the forecast period. No significant rise or inundation is expected along the Lower Volta.

Stay alert. Stay safe.

On 18th August, 2026, The Board and Audit Committee of the Ghana Hydrological Authority embarked on a site visit to the Blekusu Coastal Protection Project – Phase II, to assess progress, identify implementation challenges and strengthen measures for the project's long-term sustainability.

The project is currently recording 39% physical progress, with 14 of 40 groynes completed. The completed structures are already trapping sand and contributing to the reclamation and stabilisation of sections of the coastline.

FLOOD OUTLOOK | 14–18 AUGUST

The latest forcasts from the VOLTALARM system shows rising river flows across parts of the Volta Basin over the next five days.

Areas of concern include:
• Red Volta: Nangodi
• White Volta: Yarugu and Pwalugu
• Black Volta: Chache, Noumbiel, Bui, Lawra and surrounding communities

The anticipated spillage of the Bagre Dam, together with rising flows, could result in inundation around Bazua, Yarugu and communities in the Talensi and Nabdam Districts along the White Volta.

🚨Residents and communities in these areas are urged to remain vigilant, take necessary precautionary measures and stay informed as river levels rise.

⚠️ 10-DAY FLOOD OUTLOOK | 9th Aug - 18th Aug

The latest hydrological outlook indicates that no widespread flooding is expected across Ghana over the next 10 days. River flows are generally expected to remain normal across most monitored areas.

However, increased flood risk is expected in parts of the Savannah Region, with low to moderate flood risks also possible in parts of the Bono East, North East, Oti and Upper West Regions.

Residents in these areas are encouraged to stay alert, monitor water levels and avoid crossing flooded or fast-flowing waterways.

⛈️FLOOD OUTLOOK | 4 – 8 August 2026

The latest Volta Basin Flood Bulletin indicates that river levels across parts of the Volta Basin in Ghana are expected to rise over the next five (5) days. In addition, the anticipated spillage of the Bagre Dam could further increase the risk of flooding in some downstream communities.

Communities advised to remain vigilant include:
1. Yarugu on the White Volta, as well as Sapeliga, Talensi and Nabdam, where rising river levels combined with the anticipated Bagre Dam spillage may increase flood risk.
2. Nangodi on the Red Volta, where sharp rises in river levels are expected.
3. Lawra on the Black Volta, where river levels are also forecast to rise.

HYDRO advises residents living near rivers and flood-prone areas to:
✅ Stay informed through official weather and flood updates.
✅ Avoid crossing swollen rivers and streams.
✅ Move valuables to higher ground where necessary.
✅ Follow all instructions from local authorities if conditions worsen.

🇬🇭 Today is National General Cleaning Day!

A cleaner environment is our first line of defence against flooding.

HYDRO calls on all Ghanaians to join today's nationwide cleanup exercise by clearing drains, removing refuse from waterways, desilting gutters where possible, and disposing of waste responsibly.

Every blocked drain cleared today helps improve the free flow of stormwater, reducing the risk of flooding and protecting lives, homes, businesses, and critical infrastructure.

Flood prevention is a shared responsibility. Together, through simple actions, we can build cleaner, safer, and more resilient communities.

Join the cleanup. Protect your community. Help prevent floods.
