WFD Cycle 2 lake salinity classification
Summary
This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Salinity in lakes.
Salinity is a supporting element and is an ecological factor of considerable importance, influencing the types of organisms that live in a body of water. Salinity also influences the kinds of plants that will grow either in a water body, or on land fed by water. The tool used to provide Salinity classifications uses electrical conductivity or "reference conductivity", as a proxy for salinity. The classification method is applied to all lakes with conductivity data within the classification time window and those that are not naturally influenced by saline water ie those not in Brackish type. Classification bands are applied as part of classification are Good or Not Good dependent on the average of the reported conductivity within each waterbody.

Lineage
The Water Framework Directive classification system is risk based and focuses on where there is likely to be a problem. It uses a principle known as "one out, all out", which means the poorest individual results drive the overall classification for a water body. It reports on over 30 quality elements, grouped into ecological status and chemical status. Ecological status includes physico-chem (e.g. nutrients, pH, dissolved oxygen, ammonia) , biological elements (e.g. phytoplankton, macroalgae, fish, invertebrates) , specific pollutants (e.g. metals and compounds, organic compounds) , hydromorphology (e.g. depth, width, flow, structure). Chemical status is assessed using priority substances, priority hazardous substances and other pollutants that present a significant risk to the water environment.
