The Germama (or Kasam) River, is a tributary of the Awash River in Ethiopia. The name Germama comes from the Amharic word which means "frolicking", "boisterous", or "frisky".
The Germama is not a navigable stream, and flows with a great volume during the rainy season. It rises west of Kese Koremash, flowing east to the Awash, its course delineating a few kilometers of the northern boundary of the Awash National Park. The lowlands of the upper Germama was the location of the former Shewan district of Bulga; the lower course defines the northern boundary of the Shewan district of Menjar.
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. In December 2008, a spokesman for the Ministry announced that the project was 98% complete.
