Résumé :	A survey of the spatial and temporal distribution of the chironomid community was conducted in Lake Abbaye (France). Samples were taken monthly (from May to November) at five depths (- 1 m to - 20 m) using artificial substrates. The results showed that both depth and season contributed to variations in the chironomid community. However, correspondence analysis clearly showed that most of the variation was due to bathymetric gradients. These results indicate that information on the depth distribution of the chironomid species may be useful in lake classification. However, this classification requires multiple-season sampling, so as to include the different life-cycle patterns of species.
