The Tambacounda-Kédougou Water Resources Brigade delivered its hydrological bulletin on Tuesday, September 16, 2025, on the evolution of water levels in the Gambia River basin and its tributaries. The readings, taken at 8 a.m. at the various stations, reveal a contrasting situation between a generalized drop and an occasional rise in levels.

Tributaries in decline

In Diaguiri, a tributary of the Gambia River upstream of Mako, the water level fell by 50 cm in the space of 24 hours, from 4.89 m on September 15 to 4.39 m this Tuesday. This level also remains lower than that of the same period last year, when it was recorded at 5.15 m.

In Diahra Pont, the trend is also downward, with a drop of 1 cm (1.68 m against 1.69 m yesterday).

At the Afia Pont (Thiokoye), Goumbayel and Niokolo Koba stations, data for this morning were not transmitted. However, the previous day's measurements indicated 2.01 m, 1.96 m and 5.90 m respectively, levels lower than those of September 2024.

Finally, in Sinthiou Malème, the water level has receded so much that it no longer reaches the measuring scale.

The Gambia River at Kédougou and Mako: decline confirmed

In Kédougou, the river recorded a level of 6.51 m, a drop of 38 cm compared to the previous day. Despite this decline, the situation remains under control, with the alert level set at 7 m.

In Mako, the observed level is 5 m, down 10 cm compared to September 15. Last year, at the same time, the level was slightly higher (5.29 m).

Simenti: a notable increase

Contrary to the general trend, the Simenti station shows a significant increase: the river reaches 8.54 m, 74 cm more than the day before. This level remains, however, far from the critical threshold of 13 m, and well below the 12.50 m recorded on the same date in 2024.

Gouloumbou: slight decline

Downstream, at Gouloumbou, the water level is 8.11 m, compared to 8.18 m the day before, a drop of 7 cm. Here again, the level is lower than that observed last year (9.19 m).

Maintained vigilance

These fluctuations are a reminder of the variability of the Gambia River's dynamics during the rainy season. While the overall trend is downward, the rise observed at Simenti calls for increased vigilance, particularly in areas close to the alert levels.

The Tambacounda–Kédougou Water Resources Brigade will continue to closely monitor water level developments in order to inform local populations and authorities of any potential flood-related risks.
