Era is a reservoir located in the Atsbi Wenberta 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: 16.73 metres
Spillway width: 10 metres

Capacity

Original capacity: 1 920 000 m³
Dead storage: 480 000 m³
Reservoir area: 37 ha

Irrigation

Designed irrigated area: 100 ha
Actual irrigated area in 2002: 95 ha

Environment

The catchment of the reservoir is 16 km² large. The reservoir suffers from rapid siltation.[2][3] 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: I mean, I already hook `load` for the safety checker. But still.

gollark: Sounds hard, though.

gollark: Oh, that too.

gollark: Well, yes, I could make it just a proxy table, but then pairs would break.

gollark: So even less immutable. Oh well!
