Gambia River: Water levels continue to fall in Kédougou

In several other hydrological stations, levels also continue to trend downwards, although an increase is observed in Mako and Thiokoye.

The hydrological situation of the Gambia River and its main tributaries remains generally characterized by a decline in water levels at several monitoring stations. This is according to the daily hydrological bulletin of September 10, 2026.

At Kédougou, the main reference station, the water level recorded at 8:00 AM was 3.72 meters, compared to 4.28 meters at the same time the previous day. This represents a decrease of 56 centimeters in 24 hours. Compared to September 10, 2025, when the level reached 5.94 meters, the year-on-year decrease is 2.22 meters.

Despite this development, the level recorded in Kédougou remains well below the alert level set at 7 meters, with a difference of 3.28 meters.

Contrasting developments in Mako and Simenti

In Mako, the trend is reversed. The river level rose from 3.25 meters to 3.59 meters in 24 hours, an increase of 34 centimeters. However, compared to the same period in 2025, the level remains 1.19 meters lower. With an alert level set at 6 meters, the current difference is 2.41 meters.

The Simenti station, for its part, recorded a drop of 49 centimeters, with a level of 5.48 meters, compared to 5.97 meters the previous day. The year-on-year comparison reveals a much larger decrease of 3.28 meters, as the level was 8.76 meters on September 10, 2025. With the alert level set at 13 meters, the difference reaches 7.52 meters.

In Gouloumbou, the water level is at 6.54 meters, compared to 6.62 meters the previous day, representing a decrease of 8 centimeters. Over the past year, the decrease has been 1 meter. The level remains 5.46 meters below the alert threshold of 12 meters.

A decrease was also observed on several tributaries.

On the tributaries, the trend is also largely downward.

In Diaguiri, the water level fell from 2.05 to 1.89 meters, a drop of 16 centimeters in 24 hours. Compared to the 4.27 meters recorded on the same date in 2025, the decline is 2.38 meters.

The Niokolokoba station recorded a water level of 3.02 meters, compared to 3.56 meters the previous day, representing a decrease of 54 centimeters. Over the past year, the water level has fallen by 3.21 meters, having reached a peak of 6.23 meters on September 10, 2025.

Conversely, Thiokoye recorded a rise of 47 centimeters. The water level increased from 2.21 to 2.68 meters in 24 hours. This station also shows a positive year-over-year increase of 46 centimeters compared to the level of 2.22 meters recorded on September 10, 2025.

Yellow alert in Kédougou and Mako

The bulletin indicates a yellow alert, urging the population to remain vigilant, particularly in the areas covered by this hydrological monitoring.

Overall, however, the observed levels remain below alert thresholds at the stations for which data is available. The situation therefore remains to be monitored, particularly with the approach of the next rains and depending on the evolution of the flow rates of the Gambia River and its tributaries.
