Era Quhila 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 the Tigray Bureau of Agriculture and Natural Resources.[1]

Dam characteristics

Dam crest length: 180 metres
Spillway width: 15 metres
Original capacity: 1 185 000 m³

Irrigation

Designed irrigated area: 87 ha
Actual irrigated area in 2002: 25 ha

Environment

The catchment of the reservoir is 12.86 km² large, with a perimeter of 14 km and a length of 4550 metres. The reservoir suffers from rapid siltation.[2][3] The lithology of the catchment is Agula Shale and a bit of Mekelle Dolerite.[1] Part of the water that could be used for irrigation is lost through seepage; the positive side-effect is that this contributes to groundwater recharge.[4]

gollark: The current stable equilibrium works mostly fine but might break if enforcement gets better.

gollark: Intellectual property is vaguely weird and insane in some ways.

gollark: It's called a surprise discount.

gollark: There was an EU study on it.

gollark: So what if we combine seashells with dash?
