WFD Cycle 1 2013 Deteriorations: Water Body Status Changes in England

Cycle 1 Water Framework Directive class deteriorations for water bodies in England, assessed for the year 2013. The dataset contains statistical confidence and derived certainty estimates for real deteriorations in class status, comparing 2013 data against a 2009 baseline. Environment Agency copyright and/or database right 2016.

Use Cases

• Identify water bodies with statistically significant quality declines based on the confidence and certainty metrics.
• Analyze spatial patterns of water quality deterioration across England for 2013.
• Track changes in WFD class status between the 2009 baseline and the 2013 assessment cycle.
• Support regulatory reporting and environmental management decisions for water resources.

Strengths

• Includes statistical confidence and derived certainty metrics for each assessed deterioration.
• Focuses on a specific regulatory assessment cycle (Cycle 1) and year (2013) for England.
• Compares status against a defined historical baseline (2009).

Limitations

• Dataset is retired and superseded by a newer record, indicating it is not the current version.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and sample data are unknown, which may limit suitability assessment.
