This dam is over 100% of its full supply capacity - the level officially counted as "100% full". The extra water is held in flood-reserve storage above the normal full level, so water is usually spilling over the spillway or being released through the sluice gates to protect the dam wall, and rivers downstream can run high. It is the opposite of a shortage: the dam is full and overflowing.

Recent trend: Over the last 5 weeks, Wemmershoek Dam has risen 4.7 percentage points - about 0.94% per week.
