Sir William Garstin proposed the idea of the canal in 1907; the government of Egypt conducted a study in 1946; and plans took shape between 1954 and 1959 during the period of decolonization which included Sudanese independence in 1956. Against the context of Sudan's postcolonial civil conflict, the

, halted construction of the canal in 1984. The dispute over the Jonglei Canal, and access to Nile waters, added a significant environmental dimension to the post-1983, second Sudanese civil war, in which disputes over the religious, linguistic, and cultural elements of Sudanese national identity also played prominent roles.
Concept
Due to the Sudd swamp, the water from the southwestern tributaries of the Nile, the
Bahr el Ghazal system, for all practical purposes does not reach the main river and is lost through
evaporation and
transpiration
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth ...

east of the Sudd which would divert water from the
Bahr al Jabal above the Sudd to a point farther down the White Nile, bypassing the swamps and carrying the White Nile's waters directly to the main channel of the river.
Planning and construction

Undersecretary of State of Public Works of Egypt
The Egyptian Department of Public Works was established in the early 19th century, and concentrates mainly on public works relating to irrigation and hydraulic engineering. These irrigation projects have constituted the bulk of work performed by th ...
, created the first detailed proposal for digging a canal east of the Sudd in 1904. By bypassing the swamps, it was calculated that evaporation of the Nile's water would vastly decrease, allowing an increase in the area of cultivatable land in Egypt by two million acres.
The Jonglei canal scheme was first studied by the government of Egypt in 1946 and plans were developed in 1954-59. Construction work on the canal began in 1978 but the outbreak of political instability in Sudan has held up work for many years. By 1984 when the SPLA brought the works to a halt, 240 km of the canal of a total of 360 km had been excavated.
The rusting remains of the giant German-built excavation machine – nicknamed "Sarah" – are visible in satellite images near the south end of the canal. It was damaged by a missile. As peace was restored in 2000, speculation grew about a restart of the project. However on February 2, 2008, the Sudanese Government said the revival of the project was not a priority. However, in 2008, Sudan and Egypt agreed to restart the project and finish the canal after 24 years.

Potential impact
It is estimated that the Jonglei canal project would divert of water per year (equal to a mean annual
discharge of ),
an increase of around five to seven per cent of Egypt's current supply.
Little or no consideration had been given within Egypt to the ability of the Sudd swamplands to act as a sponge and regulator of floodwaters.

The complex and potentially catastrophic environmental and social issues involved, including the collapse of fisheries, drying of grazing lands, a drop of groundwater levels and a reduction of rainfall in the region, limits the practicality of the project.
