Water Body Status Classification Dee TraC

Water body status classification data indicates the quality or status of water bodies across a range of different parameters known as quality elements. This dataset includes the classification history of all water bodies in the Dee TraC catchment. Data may be flagged as 'Cycle 1' if the classification uses the rules initiated in 2009 when the first cycle of river basin planning began. These data end in 2015. Or the data may be flagged as 'Cycle 2' if the classification uses the latest rules used in the updated river basin plans. These data begin in 2013 and will end in 2021. For surface water bodies status classification is grouped into ecological and chemical status and for groundwater bodies they are grouped into chemical and quantitative status. This data supports the Water Framework Directive river basin management plans that can be found here: https://www.gov.uk/government/collections/river-basin-management-plans-2015 and is available to view interactively here: http://environment.data.gov.uk/catchment-planning/ManagementCatchment/3025 Attribution statement: © Environment Agency copyright and/or database right 2016.
