Initial Characterisation of Lakes Prespa, Ohrid and Shkodra/Skadar Implementing the EU Water Framework Directive in South-Eastern Europe Implementing the EU Water Framework Directive in South-Eastern Europe i Acknowledgements This publication is the result of a joint effort of ministries, competent authorities, research institutions and experts of Albania, Macedonia and Montenegro to characterise the three lake sub-basins jointly and pursuant to the EU Water Framework Directive. This endeavour, which involved the pooling of expertise from all three countries, was pursued with determination and in a spirit of cooperation at all levels: political, technical and administrative. All parties and persons involved are acknowledged for their contribution to this work. Disclaimer This publication has been prepared from original material submitted by the authors.
