vaal dam
the flood attenuation properties of the dam were severely tested in february 1996 when the largest flood ever recorded at the vaal dam site was experienced. an inflow of over was measured into the vaal dam which was already at full capacity due to good rains and it was only through the expert management of the hydrology staff at dwaf that the maximum flood released from the dam was limited to . flows above would have caused serious damage downstream of vaal dam and the situation during the 1996 flood became extremely tense as the storage in the reservoir peaked at 118.5% of full supply capacity on 19 february 1996 i.e. only of flood absorption capacity remained before the full inflow would have been released causing massive damage.
