İSKİ Reports Istanbul Dam Water Levels Dropped to 61.41% on July 9

Istanbul's water reserves are showing signs of strain as the summer heat intensifies. On July 9, 2026, the average water level across the city's dams stood at 61.41%, according to a recent announcement by the Istanbul Water and Sewerage Administration (İSKİ).

This figure marks a noticeable decrease from the previous day's 61.72%, indicating a daily water loss of 0.31%. The decline is particularly evident in several key reservoirs.

İSKİ's data reveals a varied picture across the city's water sources. While the Elmalı Dam remains well-stocked at 90.87% capacity and Ömerli Dam at 87.24%, others are significantly lower. Darlık Dam is at 79.21%, Alibey Dam at 58.02%, and Terkos Dam at 49.94%. Further down the list, Büyükçekmece Dam holds 44.11%, Sazlıdere Dam 36.89%, Kazandere Dam 38.56%, Pabuçdere Dam 34.49%, and Istrancalar Dam stands at 28.62%.

The ongoing hot weather is a primary factor contributing to this reduction in water levels, highlighting the challenges of meeting the city's water demands during the summer months.
