In the Kulkwitz opencast residual lake, which has existed since 1962 in the Leipzig lignite district (GDR), the physico‐chemical characteristics of water were recorded and qualitative and quantitative entomofaunistic inventories carried out. For the latter, a floating emergence trap was used, which caught a total of 8,397 insects above a water area of 2.25 m 2 during the summer and autumn of 1979. These insects belong to 12 families and 4 orders. Dominances, diversities and equities were determined for the Trichoptera. The results were compared with those obtained in the acid Olba opencast residual lake northeast of Bautzen, which was investigated at the same time of year.
