THE CONFLUENCE
Where both channels
meet and back up.
The engine of
everything north.
The main Luangwa channel runs along the eastern edge of Chibembe Island. The Chibembe Channel runs along its western edge. Where they converge at the confluence, water from both channels backs up — and every wet season, that backed-up flood spreads north with force. The flooding can be severe enough to periodically take the camps at Chibembe entirely.
​
The silt carried by that annual flood deposits across the entire system above the confluence — renewing the grasslands, filling the wafwas, feeding the riverine forest, rebuilding the floodplains. The confluence is not just where the walking safari began. It is the ecological engine that makes the wildlife here unlike anything else in the valley.
ONE CONNECTED SYSTEM
The reserve.
The island.
The park.
The annual flood and silt deposition affects the whole area north of the confluence equally. The wildlife does not distinguish between the reserve, Chibembe Island, and the national park beyond. They are one system — fed by the same floods, renewed by the same silt.
​
Walking anywhere above the confluence — on any part of the reserve, on the island, or in the roadless park sector to the west — is walking through habitat the confluence renews every year.
“The flooding can be severe. It has taken the camps at Chibembe more than once. The river insists on this ground — and in insisting, it makes it extraordinary.”
The Annual Flood - The Confluence
THE HABITAT
Renewed
every season.
The silt feeds every habitat type above the confluence. The grasslands and floodplains that the buffalo herds use. The wafwas — ancient oxbow lagoons — that the flood keeps full deep into the dry season. The dense riverine forest of ebony, mahogany, sausage tree, and winterthorn. The Back Lagoon. Kalovia Island. Chibembe Island. The park to the west.
​
The Luangwa is one of the last undammed rivers in Africa. This confluence is where its power is most concentrated. Ancient ebony, mahogany, sausage tree, winterthorn — all of it fed by the same annual renewal.
