The Nyabarongo (or Nyawarungu) is a major river in Rwanda, part of the upper headwaters of the Nile.
 At 297 km (184 miles), it is the longest river entirely in Rwanda.
 The river begins its course at the confluence of the rivers Mbirurume and Mwogo in the South West of the country.
 These two rivers themselves begin in Nyungwe Forest, and are considered by some to be the most distant source of the Nile.
 From its start, Nyabarongo flows northward for 85 km (53 miles), and forms the border between the Western and Southern Provinces.
 At the confluence with the river Mukungwa, the river changes course and flows eastward for 12 km (7.5 miles), then to a more South Eastern course for the last 200 km (124 miles).
 For the longest stretch of this course, the river serves as the boundary between the Northern and Southern Provinces, then between the City of Kigali and the Southern Province, and lastly between the City of Kigali and the Eastern Province.
 The river then before enters the Eastern Province and ends its course close to the border with Burundi.
 The Nyabarongo River empties both in Lake Rweru and Akagera river in a small but complicated Delta.
 The Akagera river outflows from Lake Rweru, a mere 1 km from the Nyabarongo delta.
 Almost all the branches of the Nyabarongo delta empty in the lake, however, one branch of the delta empties directly in the just formed Akagera river.
 The Akagera River eventually flows into Lake Victoria and forms the Nile.

A province is almost always an administrative division, within a country or state.
 The term derives from the ancient Roman "provincia", which was the major territorial and administrative unit of the Roman Empire's territorial possessions outside Italy.
 The term province has since been adopted by many countries, and in those with no actual provinces, it has come to mean "outside the capital city".
 While some provinces were produced artificially by colonial powers, others were formed around local groups with their own ethnic identities.
 Many have their own powers independent of federal authority, especially in Canada.
 In other countries, like China, provinces are the creation of central government, with very little autonomy.
