Betqua is a reservoir located in the Hintalo Wajirat woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1997 by SAERT.[1]
In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 23 years.[1]
The catchment of the reservoir is 1.52 km² large, with a perimeter of 4.82 km and a length of 1520 metres. The reservoir suffers from rapid siltation.[2] The lithology of the catchment is Agula Shale and 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.[3]
