The Gambia River crosses the alert level at Kédougou

The situation is more worrying in Kédougou, where the water level measured this morning is 7.94 m, an increase of 44 cm compared to the previous day (7.50 m).

At Mako, the river is at 5.37 m, compared to 5.05 m yesterday, or +32 cm. This level remains below the alert level (6 m), but already exceeds the 4.85 m observed in 2024.

In Simenti, this morning's data are not yet available. Yesterday, the height was 9.75 m, down from 11.91 m recorded at the same time last year. The alert level for this station is set at 13 m.

Finally, in Gouloumbou, the water level continues to rise, reaching 8.83 m compared to 8.64 m yesterday, or +19 cm. The level remains below the alert level of 12 m, but lower than the 9.78 m reached in September 2024.

Caution recommended

These data confirm an intensification of the flooding of the Gambia River, particularly in the Kédougou area, where the exceeding of the alert level should encourage the authorities and the population to be vigilant. Hydrological services will continue their daily monitoring to anticipate any risk of flooding.
