The Tambacounda Water Resources Brigade (BRE) published its daily hydrological bulletin on the evolution of the Gambia River and its tributaries on Tuesday, September 2, 2025. Overall, the readings indicate a drop in water levels at several stations, with the notable exception of Goumbayel and Gouloumbou, where a slight increase was observed.

Tributaries in decline

According to data collected at 8 a.m. this morning, most tributaries are experiencing a drop in their levels. At Diaguiri, the level fell from 4.11 m on September 1 to 3.93 m today, a decrease of 18 cm. The same trend is observed at Afia Pont, with a drop of 9 cm, and at Diahra Pont, where the level fell by 12 cm.

In Niokolo Koba, the drop is more moderate, with 6 cm less than the day before. On the other hand, in Goumbayel, a rise of 2 cm was recorded, unlike in Sinthiou Malème where the water no longer reaches the limnometric scale.

The Gambia River under surveillance

On the main course of the Gambia River, the trend is also marked by a slight decrease in levels at Kédougou and Mako. The Kédougou station this morning recorded 4.61 m compared to 4.65 m the day before, while the Mako station recorded a drop of 3 cm, reaching 4.15 m. These levels still remain well below the alert levels set at 7 m and 6 m respectively.

In Simenti, the drop is more significant: -35 cm in one day, with a current level of 7.70 m, compared to 8.05 m on September 1. Here too, the alert threshold (13 m) has not been reached.

A notable increase in Gouloumbou

Unlike the other stations, Gouloumbou recorded a rise of 18 cm, reaching 7.60 m this morning, compared to 7.42 m yesterday. Although this level is still far from the alert level set at 12 m, vigilance remains essential.

Levels higher than those of 2024

Compared to the same period last year, current levels are generally higher. For example, the river was only 3.20 m at Kédougou and 5.48 m at Simenti on September 2, 2024, compared to 4.61 m and 7.70 m respectively today.

The Water Resources Brigade points out that these daily readings, carried out twice a day at 8 a.m. and 6 p.m., aim to inform authorities, local authorities, NGOs, and local residents about the river's hydrological developments. These bulletins play a vital role in the early warning system for flood risks and in strengthening community resilience.
