The overall process of the intercomparison was supported and guided by the GEP core group: Martina Bussettini (Italian Institute for Environmental Protection and Research, Italy), Sebastian Döbbelt-Grüne (German Working Group on water issues of the Federal States and the Federal Government – LAWA, Planungsbüro Koenzen, Germany), Wouter Van de Bund (Joint Research Center of the European Commission), Katarina Vartia (Swedish Agency for Marine and Water Management, Sweden), Jeanne Boughaba (DG ENV, European Commission), Jan Brooke (Navigation Task Group; Jan Brooke Environmental Consultant Ltd.) We wish to thank all national experts who completed the European Questionnaire on intercomparison of Ecological Potential of HMWB – Questionnaire B "Lakes/Reservoirs". Their responses to the questionnaire served as the main source of information for this report.
