Intense rainfall observed in Istanbul during the third week of January 2026 has led to a limited but promising increase in the city’s water reserves. According to updated data from İSKİ (Istanbul Water and Sewerage Administration) as of January 15, 2026, the average dam occupancy rate has risen by 0.21% compared to the previous day, indicating an upward trend.
Dam Levels Show Modest Rise
The recent precipitation has brought a much-needed boost to Istanbul’s water supply. İSKİ’s latest figures reveal that the city’s water reserves have recorded an increase in the last 24 hours, signaling a potential move above critical levels. The occupancy rate, which stood at 23.3% yesterday, climbed to 23.51% as of Thursday, January 15. Experts anticipate a more significant recovery in the coming days, especially with the melting of snow cover in higher elevations, which is expected to accelerate water flow into the dam basins.
Detailed Dam Occupancy Rates (January 15, 2026)
The official data from İSKİ’s website provides a breakdown of individual dam levels:
- Ömerli Dam: 31.34%
- Darlık Dam: 38.33%
- Elmalı Dam: 72.42%
- Terkos Dam: 16.31%
- Alibey Dam: 18.72%

- Kazandere Dam: 7.71%
- Pabuçdere Dam: 7.92%
Although the recent rainfall has been encouraging, experts continue to urge the public to use water sparingly. The current rise in dam levels is a positive development, but sustained efforts in water conservation remain crucial for Istanbul’s long-term water security.
The city’s water infrastructure is closely monitored, and any significant changes in weather patterns or dam levels are promptly communicated by İSKİ to keep the public informed.
