Monitoring to assess the quality of river waters is undertaken in thirty-four catchments within the region. As part of this monitoring programme samples are collected routinely from selected monitoring points at a predetermined frequency per year, usually twelve spaced at monthly intervals. Each monitoring point provides data for the water quality of a river reach (in kilometres) upstream of the monitoring point. This report presents the the river water quality classification for 1991 for monitored river reaches in the Porth, Gluvian and Menalhyl catchment.
