River water quality is monitored in 34 catchments in the region. Samples are collected at a minimum frequency of once a month from 422 watercourses at 890 locations. Each sample is analysed for a range of chemical and physical determinands. These sample results are stored in the Water Quality Archive. A computerised system assigns a quality class to each monitoring location and associated upstream river reach. The 1992 Classification has been assessed using sample results collected between 1 January 1990 and 31 December 1992. The individual quality class determined for each reach is presented in a schedule format for each of the 34 catchments.
