WFD Cycle 2 DO Rivers Classification: Dissolved Oxygen Status for UK Rivers

Environment Agency data classifies river water bodies in the United Kingdom for dissolved oxygen (DO) into categories of High, Good, Moderate, Poor, and Bad. The classification is based on spot sampling monitoring data assessed against environmental quality standards derived from site typology. This dataset is part of the Water Framework Directive (WFD) Cycle 2 classification for ecological status and has been retired, superseded by a newer record.

Use Cases

• Assess ecological status of river water bodies based on dissolved oxygen classification categories.
• Analyze the impact of anthropogenic pressures on oxygen levels in rivers.
• Monitor compliance with environmental quality standards for dissolved oxygen across different site typologies.

Strengths

• Data is derived from official spot sampling monitoring conducted by the Environment Agency.
• Classifications use a standardized five-category scale (High, Good, Moderate, Poor, Bad).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is retired and superseded by a newer version, indicating potential obsolescence.
