In the City of Łódź there are 29 streams and rivers of various sizes, 18 of them named and 11 unnamed, whose total length is 125 km. The aim of the present study was gaining initial knowledge of the abundance and diversity of aquatic macroinvertebrates in water courses in the City of Łódź. Collected aquatic macroinvertebrates were represented by 18 taxons. The highest occurrence was recorded for Dipterans (Chironomidae) (present in all samples), Oligochaeta, Ephemeroptera and Gastropoda. The distribution of macroinvertebrates along the investigated streams varied very much. The Jasień and Łódka Streams turned out least abundant and taxonomically diverse in macroinvertebrates. The opposite were the Bzura and Łagiewniczanka Streams. It confirmed that usually the differences in macroinvertebrate distribution and diversity resulted from pollution of the running waters with domestic and industrial sewage, transforming of certain water courses into sewage-storm canals, regulation including covering of river beds and banks with concrete.
