Environment
The catchment of the reservoir is 12 square kilometres (4.6 sq mi) large, with a perimeter of 16 km (9.9 mi) and a length of 4,950 m (16,240 ft). The reservoir suffers from rapid siltation.[2] The lithology of the catchment is Antalo Limestone and Mekelle Dolerite.[1] Part of the water that could be used for irrigation is lost through seepage;[3] the positive side-effect is that this contributes to groundwater recharge.[4]
