Lake Great Bitter is the part of

The Great Bitter Lake (Arabic: al-Buḥayrah al-Murrah al-Kubrā) is a large saltwater lake in Egypt that forms an integral part of the Suez Canal. It is located between the northern and southern sections of the canal. Along with the Small Bitter Lake, it acts as a natural buffer and a passing lane where ships can anchor or change their position in a convoy while traversing the canal. Unlike the Panama Canal, which uses Gatun Lake and a system of locks, the Suez Canal is a sea-level waterway, allowing the Bitter Lakes to interact directly with the tides of the Mediterranean and Red Seas. The lake became famous for the "Yellow Fleet," a group of 14 ships trapped there for eight years following the 1967 Six-Day War.
