The Ruaha - also called Great Ruaha - is a river in southern Tanzania .
course
It rises in the Kipengere Mountains and flows over 900 kilometers into the Selous Game Reserve - 10 kilometers north of Masagura in the Rufiji .
In fact, with the Kilombero River , a source river of the Ruiji, it drains all areas of the southern highlands of Tanzania east of Mount Rungwe . It has its own headwaters in the Mbeya Range , the Poroto Mountains , the Kitulo Plateau and the northern Kipengere Mountains . The Ruaha collects the water of its catchment area first in the swampy but extremely fertile Usangu plains northeast of Mbeya , flows southeast along the Ruaha National Park to the Rubeho Mountains , before which it turns to the southeast, the northern boundary of the Udzungwa Mountains National Parks , then passes the Selous Wildlife Sanctuary to the north and flows into the Rufiji.
Hydrometry
The runoff of the Ruaha was measured in m³ / s at the Mtera gauge.
Water management
The power stations of the Mtera Reservoir (80 MW ) and the Kidatu Dam (240 MW) on Ruaha generate half of Tanzania's electricity. The water of the Ruaha is used extensively for irrigation of rice crops in such a way that it no longer carries water in its lower parts for almost a third of the year. In July 2011, a million people on the lower Ruaha were already stuck in a water crisis.
