Ten small streams of high altitude were assigned to the R-M4 intercalibration river type (small/medium Mediterranean mountainous rivers) and examined to determine their benthic macroinvertebrate fauna, their physicochemical and hydromorphological parameters and their water quality, quarterly for two consecutive years. Physicochemical variables were consistent with the mountainous character of the streams and fluctuated within the European Community legislation limits for drinking water. Benthic macroinvertebrate fauna communities were diverse and sensitive to organic pollution, and samples were grouped by time more strongly than place. Site size and catchment area influenced the macroinvertebrate community more than the rest of the measured abiotic variables. The water quality was good or high, but at the smaller streams its interpretation was affected by summer drought. The water quality boundaries of the Hellenic Evaluation System were harmonised with the water quality boundaries of a European benchmark database, according to the methodology followed by the Mediterranean Intercalibration Group.
