Seeking Nile River Origins via its Tributaries

November 21, 2017

By Joannah Otis for No Water No Life

This is the third blog on the Nile River in Egypt by NWNL Researcher Joannah Otis, sophomore at Georgetown University. This essay addresses the sources of the Nile  – lakes, tributaries, and a great swamp. [NWNL has completed documentary expeditions to the White and Blue Nile Rivers, but due to current challenges for photojournalists in Egypt and Sudan, NWNL is using literary and online resources to investigate the main stem of the Nile.]

For centuries, the debate over the source of the Nile River incited explorations and evoked endless questions. The Ancient Egyptians believed that the Nile originated from an underground sea or spring, but never ventured upriver to confirm their theory.  Instead they put their faith in Hapi, god of the Nile River.1 [See NWNL Blog “Finding Hapi-ness on the Nile,” .]

Interest in the elusive source arose again c. 440 BCE when Herodotus wrote in The Histories of the “fountains of the Nile.”  He asserted that melting snow from upstream mountains flooded the headwaters to create the seasonal inundation.2  It was not until 1768 when James Bruce began searching for and ultimately found the source of the Blue Nile at Lake Tana in the Ethiopian Highlands that some light was shed on the issue.  

In 1874, Henry Morton Stanley confirmed an earlier theory by John Hanning Speke that Lake Victoria was the source of the White Nile. These explorers and many others were often sponsored by the Royal Geographical Society in England and driven by their own hopes for fame.3 Today’s satellite technology and advanced resources have enabled us to positively identify Lake Tana as the source of the Blue Nile and Lake Victoria as the source of the White Nile. These two main rivers meet in Khartoum, Egypt to form the great Nile River.

The Blue Nile is the source of about 85% of the Nile’s water.4 Beginning in the Ethiopian Highlands where a plateau of basalt lava receives rain from seasonal monsoons from May to October, the Blue Nile stretches over 900 miles into Sudan. This origin point lies 2,500 meters above sea level.  Beginning its northbound route, this river flows through Lake Tana, as well as the Blue Nile Gorge.5 Lake Tana is a shallow body of water measuring 1,400 square miles, surrounded by the Amhara tribe’s ancestral lands.6 The Blue Nile Gorge, lying on the edge of Africa’s Great Rift Valley, guides the Blue Nile for 370 miles into the middle of the Ethiopian Highlands.7

While the White Nile contributes only 15% of the Nile River’s water, it is still an important ecological and hydrological presence.8 Originating in Lake Victoria and fed by the Ruvubu, Nyabarongo, Mara and other rivers, the White Nile flows through Lake Kyoga, Lake Albert, and the Sudd.9 The White Nile flows through much of the Albertine Rift Region.  It spans from the northernmost point of Uganda’s Lake Albert to the southern tip of Lake Tanganyika.10  This rift is home to a plethora of diverse wildlife, including 5,793 plant species, which brings profitable tourism to Uganda. Between Juba, Ethiopia and Khartoum, the river in Sudan drops just 75 meters. To the east and west of the river, the floodplains become savannah and then desert as lush growth that adorns the Nile’s banks disappears.11

Just south of Khartoum, lies the vast Sudd, covering most of  South Sudan. Meaning ‘obstacle’ in Arabic. the Sudd is one of the world’s largest wetlands and the Nile Basin’s largest freshwater wetland.  The Sudd is a 12,355 square-mile practically impenetrable swamp of complex channels and lagoons –  an explorer’s challenge.  Fed by heavy rainfall from April to October,12 it provides floodwater storage and water habitat for 350 plant species, 470 migratory bird species, and 100 fish species.  Antelope migrations from the surrounding arid Sahel retreat annually to the Sudd in astonishing numbers.  Around 1.2 million white-eared kob, Nile Lechwe, and tiang, as well as wild dogs, crocodiles and hippos in the Sudd are best viewed by air.   The Sudd is also the home to pastoralist Nuer, Dinka and Shilluk tribes, Nilotic peoples who practice subsistence semi-nomadic cattle breeding and some grain farming.

Ecosystems within the swamp include open waters with submerged vegetation, floodplain shrubland, surface-floating fringe vegetation, seasonally flooded grassland and woodland.13 Since most of the water that enters the Sudd evaporates due to high temperatures in Sudan, the White Nile leaves this swamp with half the power with which it enters.14  Since the 1930’s, there’ve been proposals to build a canal, today referred to as the Jonglei Canal Project, east out of the Sudd directly to the main stem of the Nile River.  It is said such a canal could increase Egypt’s water supply by five to seven percent. While Sudan and Egypt would benefit, South Sudan would see its fisheries die, grazing lands dry out and groundwater lowered.

After years of searching, the sources of the Blue and White Nile River are no longer mysteries. The number of plant and animal species who depend on them are staggering, but they also serve as important lifelines for the humans living on their banks. From water for irrigation to water for domestic use, the Nile River tributaries are vital to North African survival of all species, including humans. It would be a human and environmental tragedy if these Nile tributaries or the great Sudd were drained and disappeared, as has Africa’s Lake Chad. Thus, these waterways deserve the respect and care owed to such treasured and vital resources.

White Nile River Basin Expedition – Jinga 4/10

April 10, 2010

Welcome to #10 of 11 blogs written by Alison Jones before her departure to Uganda and Kenya as NWNL’s lead photographer. Updated 4/11: Location and text have been updated to reflect revised plans.

Location: Jinga

NWNL will end its White Nile River Basin expedition in Jinga on Lake Victoria, the head of the Victoria Nile. With the guidance of a member of the National Association of Professional Engineers, NWNL will photograph fishing on Lake Victoria, the Bujagali and Owen Falls dams, and a local resettlement village created for those who had to be moved out of the Bujagali Reservoir. Discussions will focus on the processes followed (or not followed) in constructing these hydro dams and on other Nile River Basin projects that NAPE is focused on that impact Nile watershed ecosystems and water supplies, including oil exploration and extraction from protected areas.

From the field: The end of NWNL’s Uganda expedition was the beginning: the source of the Nile at the northern end of Lake Victoria’s Napoleon Bay! In 1862 John Hanning Speke was the first European to see Rippon Falls, submerged when the Owen Falls Dam was built (1954). At this hydrological landmark the Nile River begins its 4000-mile (6400-km), 3-month-long journey north to the Mediterranean Sea.

Our visit to Bujagali Falls, downstream from Rippon Falls, gave us an understanding of the power and drama of the Nile – what Rippon Falls was like before the Owen and Kiira Dams. Bujagali Falls provide nesting sanctuary for many bird species and are home to the spiritual gods of the Busoga Kingdom. Yet these falls will also be submerged when the government, with support of international financial institutions, finishes another large hydropower dam, despite the failed productions of the two immediately upstream.

These losses will be in vain because it is all but certain that the Bujagali dam will never reach its promised production of 250 megawatts. The upstream Owen Falls and Kiira Dams, meant to produce 350–380 megawatts of power, only produce 120 megawatts now – less than half intended! This is because of Lake Victoria’s falling water levels due to climate change, increased extraction by growing populations, and deforestation in the headwaters of rivers entering the lake. Water amounts coming into the Bujagali Dam are no different than that coming into the two upstream dams, as there are no additional tributaries between them and the Bujagali site.

Additionally, there were no proper environmental or social impact studies prior to construction. The government has largely disregarded the effects of the dam on the livelihoods of local stakeholders, whether resettled or suffering from the blast impacts. Surrounding communities (comprising over 8000 people) are struggling with landlessness, food insecurity, declining environmental quality, declining health, collapse of their fishing industry, and uncertain socio-economic futures. Resettled farmers who were moved from the Nile’s riverine flood plains have been struggling for 10 years to live on reassigned land that lacks water, sanitation or trees.

On top of these socio-economic issues, the cost of the dam relative to the amount of power expected will make Bujagali Dam’s hydropower the most expensive in the world – certainly not affordable to the 90% of Ugandans who currently lack electricity. NWNL hopes that the advocacy efforts of its newest partner, NAPE (National Association of Professional Issues), will help raise awareness and mitigate some of the problems being caused by the Bujagali Dam. The World Bank and the European Investment Banks are currently conducting investigations and withholding their critical funding until the reviews are concluded and recommendations initiated.
