Dibdibo
Dibdibo is a reservoir located in the Inticho woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1999 by the Relief Society of Tigray.[1]

Dam characteristics
- Dam height: 17.8 metres
- Dam crest length: 433 metres
- Spillway width: 15 metres
Capacity
- Original capacity: 1 022 900 m³
- Dead storage: 153 435 m³
- Reservoir area: 17.24 ha
In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 22 years.[1]
Irrigation
- Designed irrigated area: 100 ha
- Actual irrigated area in 2002: 70 ha
Environment
The catchment of the reservoir is 7 km² large. The reservoir suffers from rapid siltation.[2][3] The lithology of the catchment is Adigrat Sandstone, Enticho Sandstone, tertiary basalt and Precambrian metavolcanics.[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: I... don't know, actually, are they enchantable?
gollark: The tinted glasses have no durability, see.
gollark: I did come up with the highly ideatic idea of applying lots of expensive enchantments (including thorns, which is balanced by using durability) to Bibliocraft tinted glasses, until SC removed those a while ago.
gollark: Sad!
gollark: I'm not sure, but this *may* have pushed squid into changing it to the present form.
