According to the Environmental Impact Assessment (EIA) report prepared for the Kanal Istanbul project, Istanbul will suffer an average annual loss of 32.7 million cubic meters of water. In the EIA Report prepared by the Ministry of Transport, this water loss is planned to be compensated with water from the Melen Dam. The construction of the Melen Dam, which is still under construction, was on the agenda of the public with deep cracks in its body.

The report will be suspended for 10 days for public opinion and suggestions. The EIA Report prepared by the Ministry included remarkable data on how the project will affect Istanbul's water resources.

The report stressed that Istanbul will lose 30 million cubic meters of water annually, including the Sazlıdere Dam, which will be canceled due to the Channel Istanbul Project, and 2.7 million cubic meters annually and 32,7 million cubic meters annually due to the loss in Terkos Lake.

This water loss; It is stated that it will be met by Melen Project which is being built gradually and will provide 1.08 billion cubic meters of water annually to Istanbul. In the report, the Melen project an hopes are connected pol has been a polemic issue for some time.

İBB President Ekrem İmamoğlu showed the photographs of Melen Dam, which was announced to be opened 9 years ago, in the assembly session on December 3th, and the reason for the cracks in the project is the wrong choice in construction.

We requested that the state allocate resources in 2020 to correct the project. However, no budget was allocated for construction. ISKI, the people of Istanbul, are paying for the dam. In


In the EIA report, the project passes through the Sazlıdere Dam, which is used for the supply of drinking water.

Providing an average of 49 million cubic meters of drinking water annually, 60 percent of the dam, which is approximately 30 million cubic meters per year, will be disabled due to the construction of Canal Istanbul said.

Historical Damascus Dam in order to avoid damage to the source of the current historical dam with a new embankment to the Sazlıdere Basin 40 percent of the waters from the left bank can continue to be used.

In the report, 30 million cubic meters of water can be transferred from Sazlıdere Basin to Istanbul with the construction of Kanal İstanbul Project and 19 million cubic meters of water in the basin can be continued with the new embankment.


In the last section of the canal route, Terkos Lake will enter 5.4 km into the medium-range protection area and 2.7 percent of the basin will be separated from Terkos. In this section, the construction of the Istanbul New Airport, which had already begun, was reported to have lost 0.8% of the watershed. The loss of watershed due to the channel will be 1.9 percent, which means that 2.7 million cubic meters of water cannot be used annually. Thus, with the cancellation of Sazlıdere Dam, Istanbul's water loss will be 32.7 million cubic meters.
