Rivers and lakes thumb|Relief map of the DRC The Congo River and its tributaries drain this basin and provide the country with the most extensive network of navigable waterways in Africa. wide at the mid-point of its length, the river carries a volume of water that is second only to the Amazon's. Its flow is unusually regular because it is fed by rivers and streams from both sides of the equator; the complementary alternation of rainy and dry seasons on each side of the equator guarantees a regular supply of water for the main channel. At points where navigation is blocked by rapids and waterfalls, the sudden descent of the river creates a hydroelectric potential greater than that found in any other river system on earth.
