This article has been the subject of substantial media coverage, some of which has misinterpreted our conclusions regarding the impact of dams on salmon survival in our study. Unfortunately, these erroneous conclusions were precipitated by the press release issued by PLoS Biology – in particular the misleading title. The original PLoS Biology press release on our paper was not seen by any of the authors until several days after its release. We (the authors) disagreed both with the title and some of the text in the release, and felt it misrepresented the conclusions and relevance of the paper. To PLoS Biology’s credit, when we contacted them they immediately issued a revised press release addressing our concerns. The new version does not state that dams have no effect on salmon survival, which was not what our paper stated—our paper showed that salmon survival in the Snake-Columbia R system was about the same in the Fraser River during the period of our study. We specifically noted in our paper that much work had been done to improve salmon survival at the dams over a 30-yr period. The statement that dams do not affect salmon survival is incorrect and misrepresented the conclusions in our paper.
