The objective of the project was to provide, for various river reach types, generic seasonal flow and water level regime requirements for key life stages of freshwater fish species to advise and influence the management of flow regimes. Phase I of the project identified potential tools to evaluate the potential impact of flow and water level criteria on selected fish species and populations in English and Welsh rivers to allow more scientifically robust and hence defensible assessments to be made. The tools will be developed in Phase II of the project.
