Victoria Falls / Big Tree

The second Zambezi River flood peak (5,825 m3/s ) recorded at Chavuma on 6th April 2020 arrived at Victoria Falls some 27 days later on 3rd May 2020, with a subdued magnitude of 4,568 m3/s before dropping to 4,444m3/s on 7th May 2020. The flow observed on the same date last year was 1,165m3/s. (NB: the variation in timing of the peak flood between Victoria Falls and Nana’s Farm upstream is attributable to a potential gauge shift that will have to be corrected after the flood season).
