This "Handbook for environmental design in regulated salmon rivers" is the most important result of the project "EnviDORR" (Environmentally Designed Operation of Regulated Rivers), popularly referred to as "more salmon, more power". Cross-disciplinary research has allowed us to explore the opportunities for combining the interests of salmon production and power production, demonstrated with this handbook. Involved researchers have contributed with bold and innovative efforts. We have highly specialised research teams in the fields of salmonid biology, hydrology and engineering working with hydropower in Norway. However, there is still much to learn about the complex relationships between power production, environmental factors and salmonid population dynamics. At the same time, the public authorities and the industry are facing important decisions in the coming years involving balancing environmental and power production considerations in several river systems. For this reason, the research group has had to make some hard choices based on the best of our current knowledge. We hope that this in itself will provide motivation for further development of our knowledge base, and that this handbook will be a dynamic tool which can be updated when new knowledge comes to light. The EnviDORR project has been funded by the "RENERGI" programme of the Research Council of Norway, and became part of the portfolio of the CEDREN research centre when it was established in 2009. The project has received considerable funds from the hydropower industry and the public authorities, and I wish to take the opportunity to thank the following partner organisations for their financial and technical contributions: Statkraft, Agder Energi, BKK, E-CO Vannkraft, Sira-Kvina kraftselskap, TrønderEnergi, Energi Norge (involving many of its member companies), the Norwegian Water Resources and Energy Directorate, and the Norwegian Environment Agency (formerly the Norwegian Directorate for Nature Management). Moreover, industry partners such as Hydro, Statnett and Eidsiva have also contributed funds to the CEDREN centre. In addition to the cited co-authors, many others have contributed to the preparation of this handbook. In particular I wish to extend my thanks to Maxim Teichert (a Ph.D. student working on the project), Lena S. Tøfte, Arne J. Jensen, Nils-Arne Hvidsten, Sven Erik Gabrielsen and Julie Charmasson, all of whom in their different ways aided the project and the development of this handbook. I am also grateful to those of our partners who contributed with their constructive comments to earlier drafts. As the project progressed we presented the concept to CEDREN's scientific committee and received many useful comments, in particular from Klaus Jorde and Daniel Boisclair. Jostein Skurdal has been an diligent proof-reader in the later stages.
