Istanbul, one of the world's largest cities, is facing a growing water crisis. The city's dam levels have dropped to approximately 37 percent. This figure was reported by the Istanbul Water and Sewerage Administration. The sharp decline has raised concerns among residents and officials. Water supply has become a critical issue for the city.
In March 2026, the average dam level was around 64 percent. However, levels fell steadily during the hot summer months. By late September, the rate had dropped to just 36 percent. Some smaller dams were reported to be nearly empty. Pabuçdere Dam, for example, fell to only 3 percent capacity.
Istanbul's population exceeds 16 million people. The city consumes roughly 3 million cubic meters of water daily. Much of this supply comes from external sources like the Melen River. Experts have stated that reservoir recovery alone cannot ensure long-term security. If the city invested more in conservation, future shortages would be reduced.
Water scarcity is not unique to Istanbul but affects many large cities worldwide. Climate change and rapid urbanization have made the problem worse. Authorities have urged residents to adopt sustainable water habits. Experts believe that better infrastructure could reduce significant water losses. Solving this crisis will require both individual effort and strong public policy.
