Arato is a reservoir located in the Inderta woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1997 by SAERT.[1]

Dam characteristics

Dam height: 20 metres
Dam crest length: 443 metres
Spillway width: 20 metres

Capacity

Original capacity: 2 590 000 m³
Dead storage: 647 698 m³
Reservoir area: 40 ha

Irrigation

Designed irrigated area: 120 ha
Actual irrigated area in 2002: 27 ha

Environment

The catchment of the reservoir is 12 km² large, with a perimeter of 16 km and a length of 4950 metres. The reservoir suffers from rapid siltation.[2] The lithology of the catchment is Antalo Limestone and Mekelle Dolerite.[1] Part of the water that could be used for irrigation is lost through seepage[3]; the positive side-effect is that this contributes to groundwater recharge.[4]

gollark: You want death rate.

gollark: No, that';s total.

gollark: Well, deaths per amount of people is more reasonable.

gollark: The UK isn't far behind, what joy.
