Abstract Lake Chilwa, a fairly large, turbid, brackish and very shallow endorheic lake in Malawi, Central Africa, dried up completely in 1968 and filled up again in the following wet season. Compared with the zooplankton in the drying, filling and post-filling phases (1966–1971), differences in their composition, density, distribution and reproduction were found in 1975–1976, a year when the lake was 1–2 metres deeper. This situation is discussed in relation to environmental factors, fish predation and the supply of detritus from the surrounding Typha swamp, to illustrate the relative stability of the zooplankton populations in periods between lake recessions.
