Maguga Dam — labyrinth spillway
A folded concrete weir leads water beneath a road bridge and down a broad chute.
The story behind the place
Maguga Dam is part of the joint water infrastructure managed by the Komati Basin Water Authority. The spillway is a distinctive piece of that engineering: its reinforced-concrete labyrinth leads into a concrete-lined chute, with water continuing toward the Komati River. The main dam is a rockfill embankment with a clay core. Looking at the spillway reveals how a reservoir needs carefully designed routes for excess water as well as a wall to retain it.
