TurkeyReservoir levels

Data from Istanbul's water utility İSKİ, published by Anadolu Agency, show the average fill of the dams supplying the city rising from 38.06 per cent on 14 October to 48.02 per cent on 16 October, after rain that began on the evening of 13 October. Stored volume on 16 October was 416.74 million cubic metres against a capacity of 868.68 million. The daily Dünya, carrying a later Anadolu report, gave 52.43 per cent on 18 October, against 24.51 per cent on the same day in 2025. Among İSKİ's readings for 18 October since 2016, only 2017 (52.66 per cent) and 2018 (53.63) were higher. Daily consumption was 3.167 million cubic metres on 15 October. The two reports give different readings for individual dams, so none are quoted here.
