The lake level was low. Three years later, Joseph Thomson found a fast-flowing river at the same spot. By 1882, Hermann von Wissmann watched a wide and fast effluent pouring out of Lake Tanganyika, with the lake itself 4.8 meters below its highest watermark. The same river, on four visits across eleven years, had been three completely different things. The Lukuga is Africa's most sensitive hydrological instrument - a river whose flow depends on centuries of climate, not just this year's rains.

Lake Tanganyika is enormous - the second-largest lake in Africa by area, the deepest in the continent, and one of the oldest bodies of fresh water on Earth. Water pours in from its watershed. Most of it leaves the lake as evaporation under the central African sun. Only 18 percent...

Before the Virunga volcanoes erupted and blocked the northward drainage of Lake Kivu, the Kivu waters flowed toward Lake Edward. When that path closed, the water had to go somewhere - it went south, through the Ruzizi Rive...

Before Europeans drew maps of the region, the Lukuga's northern bank, together with Lake Tanganyika, the Luvua River to the south, and the Lualaba, formed a territory occupied by the Hemba people in the western part and the Tumbwe people in the more mountainous east. Tumbwe leade...

Around 1871 David Livingstone noticed a break in the hills through which something he called the 'Logumba' passed, and suggested it might be an outlet of Lake Tanganyika. Verney Lovett Cameron confirmed in May 1874 that it was the only outlet - though he could not find a guide wi...
