Ruaha River
Eastern Tanzania Region
The Great Ruaha River is a significant natural feature in south-central Tanzania, flowing approximately 475 kilometers through the Usangu wetlands and Ruaha National Park before joining the Rufiji River. Its basin covers about 83,970 square kilometers, sustaining local populations through irrigation, fishing, and livestock activities. The river originates in the Kipengere Range in the Njombe Region and flows through important agricultural plains, including the Usangu plains, which are central to Tanzania's irrigated farming. The river also supports two major hydroelectric dams, Mtera and Kidatu, which together generate around half of Tanzania's electricity. Ecologically, the river hosts at least 38 fish species and traverses key wildlife areas such as the Selous Game Reserve. However, since the early 1990s, the Great Ruaha has experienced reduced flow and seasonal drying, largely due to poor water management and extensive irrigation schemes, posing environmental challenges. This river is essential for both human livelihoods and biodiversity in the region, making it a critical natural resource in Tanzania.

Histoire
The Great Ruaha River's headwaters arise in the Kipengere Range and it has long been integral to the surrounding regions' agriculture and livelihoods.
In the 20th century, the construction of the Mtera and Kidatu dams harnessed its flow for hydroelectric power, supplying about 50% of Tanzania's electricity.
Since the 1990s, water flow has declined significantly, with sections drying up due to increased irrigation and poor water management practices.
These changes have raised environmental concerns and highlighted the river's critical role in regional development and conservation.
