The Ruhuhu is a river in southwestern Tanzania .

course

It rises in the Njombe region , on the eastern slope of the Livingstone Mountains in Tanzania , where it first flows to the southeast and then turns west to Lake Malawi , which it feeds from Tanzanian territory. It is over 300 km long, of which the last 100 km is a single deep gorge. Its mouth is near the city of Manda , the former Wiedhafen .

Catchment area

With over 14,000 km² (depending on the data source between 14,070 and 14,200 km²) the Ruhuhu catchment area is the largest of the Malawi tributaries and by far the largest in Tanzania. As the longest river that flows into Lake Malawi, by convention it is the source of the Shire , which drains the lake. The Ruhuhu has water all year round.

Hydrometry

The discharge of the Ruhuhu was measured for 43 years (1971–2015) at the Kikonge gauge, about 20 km above the mouth, in m³ / s. However, the values ​​in other sources are given around a factor of four higher.

The Tanzanian government decided in 2016 to install a hydropower plant with an expected output of 300 MW ( Kikonge Hydroelectric Power Station ) at this point .
