CHAPTER 6 7 The summary page (Figure 6.6) provides overall summaries including tables for the status classification (Figure 6.7),
the reasons for not achieving Good status, ie the reasons for failure to achieve environmental objectives (Figure 6.8), the
environmental objectives (Figure 6.9), summary statistics (Figure 6.10) and information about the programme of measures.
The information is updated regularly and can be switched from the latest data to the data in the River Basin Management Plan.

Far more detail is provided in the data sets that can be downloaded from links on the river management catchment summary
page, including details for the classification of all elements in all monitored water bodies, reasons for not achieving Good
status or deterioration for every failing element in every water body, measures to restore good quality, environmental quality
objectives for every water body, and the protected areas in each water body.
