In late July 2026, the Istanbul Water and Sewerage Administration (İSKİ) reported a rapid decline in the city’s reservoir water levels due to soaring temperatures, low rainfall, and high consumption. During this period, the average fill rate of Istanbul’s ten reservoirs dropped from below 60% to approximately 55.49%, with specific reservoirs like Pabuçdere recording levels as low as 25.19%. By mid-August 2026, the average water level in Istanbul's dams had fallen further below the 50% threshold, dropping to approximately 49.94%. 49.54%. While some reservoirs such as Elmalı (over 80%) and Ömerli (71.05%) maintained higher levels, several western basin reservoirs reached critical lows, including lows. Specifically, Pabuçdere recorded occupancy at 16.8%. Experts approximately 16%, while Kazandere and Sazlıdere also showed significantly depleted levels. Experts, including Prof. Dr. Hüseyin Toros from Istanbul Technical University, noted that these levels represent one of the three lowest periods in the last decade, as the decade. The city faces ongoing pressure from daily water usage averaging between 3 and that is approaching 3.5 million cubic meters. meters, exacerbated by rising temperatures and high evaporation rates.
