Abstract

The level of Lake Kariba steadily fell during the period 1 June 1979 to 2 Feb 1980, except for a 2-wk period during Dec when it was allowed to rise slightly. Following this the level was again drawn down in anticipation of the Upper Zambezi flood water reaching the lake. At its highest level in June 1979 the lake was 487.42 m above sea level but by Feb 1980 it had dropped to 484.53 m, a total drop of 2.89 m. This left a considerable area of exposed shoreline and a large number of stranded mussels. This report presents the results of an attempt to estimate the mussel mortality, carried out from 28 Jan to 1 Feb 1980. The study area extended from the Charara river mouth to Andora harbour with a total of 24 stations.
