Guidance to Environment Agency and Scottish Environment Protection Agency staff, researchers and external agencies involved in implementation of the Water Framework Directive.
This project’s aim was to develop a method to carry out the initial risk assessment for lakes, specifically in relation to nutrient pressures. Approaches of increasing sophistication were developed to assess the size of diffuse and point-source nutrient pressures. A nutrient classification for different lake types was produced to assess the impact of these pressures. Approaches to ecological classification for phytoplankton composition and abundance in lakes and slow-moving rivers were also developed, taking phytoplankton as the biological element most sensitive to nutrient pressures.
