Great Bitter Lake
The original canal featured a single-lane waterway with passing locations in the Ballah Bypass and the Great Bitter Lake. It contained, according to Alois Negrelli's plans, no lock systems, with seawater flowing freely through it. In general, the water in the canal north of the Bitter Lakes flows north in winter and south in summer. South of the lakes, the current changes with the tide at Suez.
