A new Earth Economics report evaluates the cost-effectiveness of continued dam operations as compared with the benefits of a free-flowing Lower Snake River. Earth Economics’ latest analysis took a look at four dams along the Lower Snake River in Southeast Washington, investigating whether the dams’ benefits outweigh the costs. As they stand, the dams return only $0.15 on every dollar, but a free-flowing Lower Snake River has an estimated $4.30 return for every dollar.
