Abstract: The first stage of the Kis-Balaton Protective System has been operating since 1985. It was constructed with the aim to inhibit or reverse the deterioration of water quality in Lake Balaton. From 1985 through 1989, 32 cladoceran and 13 copepod species were recorded from the various habitats of it (plankton, mud surface, phytal). On the basis of species composition of planktonic crustaceans five water quality regions could be distinguished in this impounded water between 1985 and 1987, while in 1989 only 3. In the samples collected from mud surface by means of funnel traps only few species were found, the copepod species Acanthocyclops robustus f. limnetica being also dominant in the plankton was the most frequent. Along the longitudinal axis of this lake the number of individuals diminished in southern direction. The results showed that the lake is still young, and the assemblages of planktonic and mudliving crustaceans are not constant.
