Istanbul's water needs are largely met by the Ömerli and Elmalı dams on the Anatolian Side. High temperatures and increased water consumption during summer months affect dam levels.
In its updated statement, Istanbul Water and Sewerage Administration (ISKI) shared the recent change in dam occupancy rates in Istanbul. So, what is the occupancy rate of Istanbul dam on September 6, 2026?
CURRENT DAM OCCUPANCY RATES 6 SEPTEMBER 2026
According to the official data shared by İSKİ as of Sunday, September 6, 2026, the general average occupancy rate of the dams that meet Istanbul's water needs has decreased to 42.06 percent. The fact that the general average, measured as 58.68 percent in mid-July, entered a rapid downward trend with the beginning of September, clearly reveals the high evaporation and increased water consumption caused by summer heat.
While the Ömerli and Elmalı dams on the Anatolian Side continue to bear the city's water load, the occupancy rates in the western basins such as Istrancalar, Pabuçdere and Sazlıdere on the European Side have fallen below critical levels.
