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
: 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 square kilometres (4.6 sq mi) large, with a perimeter of 16 km (9.9 mi) and a length of 4,950 m (16,240 ft). 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]
