During the rainy season, water levels in the Gambia River and its tributaries have shown significant fluctuations. Initially, monitoring stations reported mixed trends, with some areas like Gouloumbou seeing increases while others like Kédougou and Simenti experienced declines. At that stage, no locations had reached their designated alert thresholds.

By late August, water levels began rising more sharply. In Kédougou, the river approached a 7-meter alert threshold following a rapid daily rise. Other stations, such as Simenti, recorded increases of over one meter in 24 hours. While levels in some areas like Diaguiri and Thiokoye have declined, they remain higher than the previous year. Hydrological services have advised nearby populations to remain vigilant due to potential flood risks.
