Sip Canal
Serbia
The Sip Canal (Serbian: / Sipski kanal) was a ship canal on the Danube, in eastern Serbia. It was constructed as part of a massive international effort to make the navigation through the most dangerous sections of the Iron Gates gorge safer and easier. Opened in 1896, with participation of three royal heads of state, the Sip Canal was flooded in 1969 when the artificial Đerdap Lake was formed after the dam of the Iron Gate I Hydroelectric Power Station on the Danube was built. In terms of navigation, it was the most important of all 7 canals cut through the gorge.
