The Tambacounda-Kédougou Water Resources Brigade published its hydrological bulletin on the water trends in the Gambia River and its tributaries this Wednesday, September 24, 2025. The measurements taken at 8 a.m. confirm a general downward trend, with some stations recording a slight increase.

Tributaries: marked decline at Diaguiri and Afia Pont

In Diaguiri, the water level has receded significantly, reaching 3.48 m compared to 4.64 m the day before, a drop of 116 cm. On the same day last year, the level was at 4.64 m.

The situation is similar at Afia Pont (Thiokoye), where the level fell to 3.27 m from 4.26 m on September 23, a drop of 99 cm. In comparison, the river reached 6.15 m on the same date in 2024.

On the other hand, a slight rise of 10 cm was recorded at Diahra Pont, with a current level of 1.67 m.

In Niokolo Koba, no measurements were taken this morning, but yesterday the level was at 5.78 m, well below the 8.42 m observed on September 24, 2024.

As for the Goumbayel and Sinthiou Malème stations, the level is now too low to reach the scale.

A situation to monitor

Overall, today's bulletin reveals that most stations in the Gambia River Basin are experiencing a significant drop in water levels compared to the previous day, but also compared to last year. Only a few stations, such as Diahra Pont and Gouloumbou, are showing an upward trend.

Hydrological authorities are calling for continued vigilance, particularly in areas where water levels could rise due to rainfall upstream.
