A Framework for Estimating the Costs and Benefits of Dam Removal

Author: Whitelaw & Macmullen, ECONorthwest (2002)
Geography: U.S.
Level of Detail: Case study, Decision support tool, Economic valuation

Availability: Publicly Available

Water Management Strategies: Dam removals, Land Management

Specific Benefits or Trade-offs: Habitat and biodiversity, Land and environment, Local economy, People and Community

A Framework for Estimating the Costs and Benefits of Dam Removal examines the case study of removing dams from the Snake River. The authors use this analysis to provide a list of recommendations for performing a cost benefit analysis on dam removal. They emphasize relying on simplistic endangered species vs endangered jobs can distort calculations and miss other important areas of economic growth.

Just the FACTS: Dams in California

Author: Public Policy Institute of California (PPIC) (2017)
Geography: Western U.S.
Level of Detail: Qualitative description

Availability: Publicly Available

Water Management Strategies: Dam removals, Land Management, Surface Water Storage

Specific Benefits or Trade-offs: Energy, Energy production, Flooding, Habitat and biodiversity, Land and environment, People and Community, Recreation, Risk and Resilience, Water supply reliability

Just the FACTS: Dams in California highlights several key considerations of dams in California. The considerations include the crucial role of dams in water management in California, the multiple objectives that dams are designed to meet and the conflicts that exist within these objectives, the need for dam infrastructure upgrades, the benefits of new dams, and the reasons to remove old dams. The multiple benefits of dams include supplying water, reducing flood risk, providing energy, and recreation, however, in order to provide these benefits dam operations conflict with several public benefits, including wildlife habitats and recreation.

Global Review of Physical and Biological Effectiveness of Stream Habitat Rehabilitation

Author: Roni, Hanson, & Beechie, (2008)
Geography: Global
Level of Detail: Qualitative description

Availability: Paywall

Water Management Strategies: Dam removals, Floodplain connectivity and rehabilitation, Land Management, Riparian buffers, Sediment addition, Stream protection and restoration

Specific Benefits or Trade-offs: Ambient water quality, Habitat and biodiversity, Land and environment, Water quality

Global Review of Physical and Biological Effectiveness of Stream Habitat Rehabilitation is a literature review that assesses 345 studies of inland freshwater habitat restoration projects throughout the world. The case studies include projects such as road improvements, riparian restoration, floodplain connectivity restoration, instream habitat improvement, and nutrient addition, as well as many more. For each case study, an analysis was conducted on the techniques used, project outcomes, and overall effectiveness in improving habitat and water quality, and increasing fish production. The report concludes that reconnection of isolated habitats, instream habitat improvement, and floodplain restoration have been proven to be effective in improving habitats and increasing fish production.
