Lake Rukwa is a shallow, endorheic lake in the Rukwa Rift Valley of southwestern Tanzania and is one of the larger lakes in that region. It lies within a tectonic rift system and forms part of a regional wetland complex.

The lake is used locally for fishing and supports wetlands and reedbeds that attract waterbirds and local wildlife. Shores are generally sparsely settled and there are few developed tourist facilities, so visits are typically for birdwatching, fishing or to see the lake landscape rather than amenities.

Lake Rukwa is a natural feature shaped by Rift Valley tectonics; it has no permanent surface outflow and has experienced substantial changes in extent over recent decades. Local communities have long used the lake for subsistence fishing and limited agriculture on surrounding flats.

Geographically the lake sits in southwestern Tanzania in the Rukwa Valley; the nearest regional centre is Sumbawanga to the west. The surrounding landscape is a mix of flat lakeshore plains, seasonal wetlands and distant rift escarpments.

  • Getting there: Access is usually via the regional town of Sumbawanga or by unpaved roads; services are limited and seasonal flooding can affect access.
  • Fluctuating levels: Water levels and shoreline extent change seasonally and between years, influencing fishing and wetland habitats.
