Diversity of the Tanytarsini chironomids (Diptera: Chironomidae) collected on the Żarnowieckie Lake (northern Poland) in the early 1980s and in 2008–2009 was compared. The analysis demonstrated a significant impoverishment of the Żarnowieckie chironomid fauna. Within less than 30 years, the number of Tanytarsini species dropped from 21 to 14, and the fauna became dominated by common eurytopic species Cladotanytarsus atridorsum Kieffer (more than 73% of all individuals collected in 2008), C. mancus (Walker) (more than 8%), and Paratanytarsus inopertus (Walker) (more than 9%). The four species rare in Poland [Tanytarsus niger Andersen, Rheotanytarsus muscicola Thienemann, Stempellinella brevis (Edwards), Paratanytarsus tenellulus (Goetghebuer)], recorded in the area in the 1980s, were absent in 2008–2009. The reduction in the Tanytarsini diversity is interpreted as an effect of unstable environmental regime of the lake following its artificial modification in 1983 to serve the needs of the "Żarnowiec" pumped storage power station, and interventions related to the planned construction of a nuclear power plant on the lake.
