Dam characteristics
editDam crest length: 176 metres. Exceptionally, among the many dams in Tigray, this dam was breached around the year 2000, due to high positioning of the spillway and hence overtopping of the dam. Around 2010 the breach was closed and the dam height increased. The dam is now operational.
Environment
editThe catchment of the reservoir is 8.77 km2 large, with a perimeter of 13 km and a length of 4700 metres. The reservoir suffers from rapid siltation.[2] The lithology of the catchment is Enticho Sandstone and Precambrian metamorphic rocks.[1]
