RIVER QUALITY REPORT Period to end of June 1991 Freshwater Rivers ComplianceTable 1 gives details of the 94 sites that failed their RQO's in the year to March 1991. The number of sites sampled was 575. Therefore about 16% of the sites failed their RQO.Table 2 gives details of the class achieved by all reaches as per previous reports.Table 2(A) is a matrix showing the total lengths of river in each class against objectives, while Table 2(B) shows this graphically.78/659/EEC Fisheries Directive Compliance (Table 3)This table shows that 21 of the 178 sites sampled fail the above directive. There are currently 57 sites on river reaches classified as Salmonid and 121 on those classified as Cyprinid.EEC Dangerous Substances Directives (Table 4J_This table gives details of the freshwater river sites that fail parameters assessed under the various directives. All parameters are assessed as annual averages.The Tideway (Tables 5 and 61Table 5 details compliance of the three tideway reaches against the guality objectives in the quarter April to June 1991.Table 6 details sites failing the EEC Dangerous Substances Directives in the year to June 1991.
