Expected rises in river levels over the weekend will remain below warning thresholds

Water levels in the country’s major and significant dams remain stable. As of 10 September 2026, the total stored volume stands at 4462.9 million cubic meters, representing 68.28% of their total capacity. Available water resources are more than 15% higher than during the same period last year, with the fill rate at its highest level in the past 8 years.

Dams primarily intended for drinking and domestic water supply remain the most full - at 82.33% of their total capacity. Dams for electricity generation are at 73.86% full, those for irrigation are at 52.39% full, and dams for backup drinking and domestic water supply are at 47.90% full of their total capacity.

According to data from the National Institute of Meteorology and Hydrology, short showers accompanied by thunderstorms are expected this afternoon in some areas, mainly in the mountains of Western Bulgaria. On Friday, isolated brief showers are possible in the afternoon, mainly in the mountainous regions of Southwestern Bulgaria.

Over the weekend, the rain will spread to more areas. Showers are expected in many parts of the Western half of the country, and on Sunday they will reach central Bulgaria as well. In some areas of the Eastern regions, short and temporarily intense showers are possible.

Today and tomorrow, river levels will remain largely unchanged. As a result of the expected rainfall on September 12 and 13, river levels may rise. However, water levels will remain below the warning thresholds.

The Ministry of Environment and Water continues to monitor the state of water resources and developments in the hydrometeorological situation. The Ministry reminds local authorities to implement the measures outlined in the Flood Risk Management Plans for the period 2022-2027 and to monitor the latest hydrometeorological information and forecasts for hazardous events, available at the ministry’s official website.

The Ministry of Environment and Water manages water resources in 52 major and significant dams.
