Dam breaching and Chinook salmon recovery

The Report by Kareiva et al. on recovery and management options for spring/summer chinook salmon (1) has the potential to have a major impact in deciding whether to breach dams on the Snake River. Based on interpretation of their model results, they argue that dam breaching would be insufficient to reverse the decline of salmon. An examination of the specifics of their model, however, suggests that, despire their argument, dam breaching remains a viable recovery option for chinook salmon.
