The Tambacounda-Kédougou Water Resources Brigade published its daily hydrological bulletin on the situation of the Gambia River and its tributaries this Sunday, September 21, 2025. Data collected at the various hydrometric stations show contrasting trends, with a sharp decline in Kédougou and notable increases further downstream.

Tributaries in decline

Overall, the tributaries of the Gambia River are showing a downward trend. At Diaguiri, the water level fell from 5.54 m on September 20 to 5.46 m this morning, a decrease of 8 cm. The same is true at Afia Pont (Thiokoye), where the level fell to 5.63 m, a decrease of 9 cm.

The most significant drop was observed at Diahra Pont, with a 79 cm drop in one day. At Niokolo Koba, the level remained relatively stable, losing only 1 cm. However, the Goumbayel and Sinthiou Malème stations did not record any usable data.

Kédougou returns to alert level

On the main course of the Gambia River, the Kédougou station shows a spectacular drop: 6.90 m compared to 7.94 m the day before, a decrease of more than one meter (104 cm). This level falls below the alert level set at 7 m, after several days of vigilance.

Downstream increases in Mako, Simenti and Gouloumbou

Unlike Kédougou, stations further downstream are recording increases. In Mako, the water level rose by 21 cm to reach 5.58 m. The trend is similar in Simenti, with a rise of 21 cm to 10.29 m, although well below the alert level of 13 m. In Gouloumbou, the level reached 9.03 m, up 20 cm compared to the previous day.

Surveillance still crucial

These variations reflect the complex dynamics of the Gambia River basin. The DGPRE and the Water Resources Brigade emphasize that daily monitoring of these stations is an essential tool for anticipating flood risks and strengthening the resilience of riverside populations in the face of climatic hazards.
