Dam characteristics
Dam height: 10.5 metres
Dam crest length: 196 metres
Spillway width: 3 metres
Capacity
Original capacity: 118944 m³
Dead storage: 3944 m³

Environment
The catchment of the reservoir is 1.21 km² large, with a perimeter of 4.62 km and a length of 1780 metres. The reservoir suffers from rapid siltation. The lithology of the catchment is Agula Shale. 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.
