Felaga
Felaga 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 1996 by Tigray Bureau of Agriculture.[1]

Dam characteristics
- Dam height: 11.9 metres
- Dam crest length: 115 metres
- Spillway width: 15 metres
Capacity
- Original capacity: 900000 m³
- Dead storage: 115000 m³

Environment
The catchment of the reservoir is 8.16 km² large. The reservoir suffers from rapid siltation.[2][3] The lithology of the catchment is Enticho Sandstone and precambrian rock.[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'm sure there are many subscription services with a better value proposition than "you get more emojis".
gollark: Indeed.
gollark: Consider what else you could do with £5 or whatever per month. You could buy 1 to 4 cups of coffee. You could save that amount of money for later use. You could buy random trinkets. You could subscribe to some other random service.
gollark: > Should I get nitro<@585502232397742101> Is, er, fancy emojis and the opportunity to very slightly improve (boost) a server worth £5 or so a month to you?
gollark: Is that just based on number of tests? you could have people be tested multiple times.
