By the end of the year 1974, the French Ministry of Agriculture's Service Régional de l’Aménagement des Eaux de Lorraine possessed a wealth of water-quality data covering the rivers and streams of Lorraine from 1968 to 1974. The data were in the form of 475 individual records each comprising : (a) A physical-chemical analysis (21 factors), (b) A description of the stream (20 factors), and (c) At least one list of macro-invertebrate benthos and periphyton. The data were analysed automatically with the assistance of the Biometrics Laboratory of the Centre National de Recherche Forestière at Champenoux, the aim being : (1) To establish the biotic communities (fauna), (2) To adapt the Biotic Index method suggested in 1968 by CTGREF 2 to the wat...
