[3] The Germama is not a navigable stream, and flows with a great volume during the rainy season.

The Kessem River passes an altitude drop from more than 2,000 m on a flow length of ca.130 km.

[4] The steep gradient of the river profile is the reason for its turbulent flow regime, which is also reflected in its name.

The Ethiopian Ministry of Water Resources began construction of a dam on the Germama in 2005, which would help irrigate areas along both sides of the river, and in the Dofen and Kebena Mountains.

The dam was shut down in order to fix this issue, and was expected to resume full capacity within a year of January, 2024.
