Istanbul Dam Occupancy Rates on February 9, 2026: ISKI Updates Current Data
Istanbul, February 10 – The Istanbul Water and Sewerage Administration (ISKI) announced the latest dam occupancy rates for the megacity as of February 9, 2026. The overall dam occupancy rate has reached approximately 35%, showing a minor improvement in water reserves following recent seasonal rainfall.
Slight Improvement in Water Reserves
The question of “how much water is left in the dams?” is a critical one for Istanbul, and the current figures are shaped by the levels of key dams such as Ömerli, Darlık, and Elmalı. These data provide essential guidance for residents and authorities, particularly for those wondering if “Istanbul’s dam occupancy rates are increasing or decreasing?”
Current Status of Dams as of February 9, 2026
According to information obtained from ISKI’s official website, the general occupancy rate of dams in Istanbul was measured at 35.8% on Monday, February 9.
Detailed Dam Occupancy Rates (February 9, 2026):
- Ömerli Dam: 49.2%
- Darlık Dam: 53.4%
- Elmalı Dam: 92.54%
- Terkos Dam: 22.48%
- Alibey Dam: 30.58%
- Büyükçekmece Dam: 25.23%
- Sazlıdere Dam: 22.14%
- Istrancalar Dam: 70.45%
- Kazandere Dam: 10.77%
- Pabuçdere Dam: 10.64%
The relatively high levels in dams like Elmalı and Istrancalar offer some relief, while others, such as Kazandere and Pabuçdere, remain at critically low levels. This disparity highlights the varying impact of rainfall across different catchment areas feeding Istanbul’s water supply.
Implications for Istanbul’s Water Supply
Despite the slight overall improvement, the 35% occupancy rate underscores the ongoing need for water conservation and careful management of resources. Istanbul, a megacity with a population exceeding 15 million, relies heavily on these dam systems for its daily water needs. The winter rainfall, while beneficial, has not yet fully replenished the reserves to desired levels, especially after periods of drought experienced in previous months.
ISKI continues to monitor the situation closely, emphasizing the importance of sustainable water use practices among residents and businesses. Public awareness campaigns are expected to continue, encouraging responsible consumption to ensure the long-term water security of the city.
Future Outlook and Measures
Authorities are evaluating various strategies to enhance water resilience, including potential investments in new water infrastructure and exploring alternative water sources. The current data will inform future decisions regarding water management policies, aiming to mitigate the risks associated with climate variability and increasing urban demand.
The current figures provide a snapshot of Istanbul’s water situation, indicating a fragile but improving trend. Continued rainfall in the coming weeks will be crucial for further recovery of dam levels, ensuring a more secure water supply for the spring and summer months.
This update from ISKI serves as a vital indicator for environmental experts, urban planners, and the general public, reinforcing the critical role of natural precipitation in maintaining the city’s essential resources.
