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 large, with a perimeter of and a length of . 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]
