The Life Cycle of Dams: An Analysis of Policy Change on the Rogue River, Oregon Wendy Mc. Dermott Resource Management Graduate Student Central Washington University May 24, 2011
Case-study approach provides for lessons-learned ~~~~~~~~~~~ “Effective science and well-informed public policy are the avenues to successful management of environmental resources. ” ~ William Graf (1992) “Through documentation and analyses of case studies we can be guided by the light of science rather than curse the darkness in which we must make projections. ” ~ Bruce Babbitt (2002)
A Dammed Nation Problem ~80, 000 dams in the U. S. Disrupts natural flow regime Fragments ecosystems Block migrating fish passage Social displacement, migration and resettlement New Era of River Mgmt Convergence of a number of economic, social, and environmental factors Reflected in changing policies to re-create more natural ecosystems and to conserve natural & cultural resources Source: National Inventory of Dams, 2010
Predominant Reasons for Dam Removals in the U. S. Environmental and Social Concerns Age, Functional Status Economics & Cost-benefit Analyses Marginal Benefits from Continued Operations FERC Relicensing Process Hazard & Safety Ratings Changes in Public Opinion
Rogue River Basin ~ 13, 350 km² (5, 156 mi²) Five Subbasins: Applegate, Illinois Lower Rogue Middle Rogue Upper Rogue Over 80 dams in the Basin
Gold Ray Dam Grants Pass Medford Savage Rapids Dam Ashland
The Rogue River 346 km (~215 mi) in length Originates at Boundary Springs in Crater Lake National Park Premier salmon & steelhead fishery, whitewater rafting, and rugged scenery One of original 8 rivers named in Wild & Scenic Rivers Act of 1968

Rogue River Socio-Economics Agricultural Industry: 2500 directly employed 9000 indirectly $141 million in crop & livestock sales pears, wine grapes, alfalfa, corn (Climate Leadership Initiative, 2008)
Rogue River Socio-Economics Fisheries $1. 4 million commercial fishing $16 million sport fishing $1. 5 billion non-use values Recreation/Tourism $30 million in economic output 445 full- and part-time jobs (ECONorthwest, 2009)

Lowry’s Theoretical Framework for Policy Changes Source: Lowry (2003)
Independent Variables POLITICAL RECEPTIVITY Interactions btwn Coalitions Reflect Political Receptivity Identify primary stakeholders What percent in favor of removal? Decision-making Venue Level of decision-making Points of Access Costs of Maintaining Status Quo Which Alternative costs more? Scientific Info on Potential Benefits Widely Embraced Broad-based scientific consensus PHYSICAL COMPLEXITY Scale – Political Jurisdictions Not # of actors, but diversity of their viewpoint Is there agreement? Dimensionality – (Decision Points along the way) Unidimensional – less layers of government Multidimensional – more layers Scope of Undertaking Size of dam, miles of river to be restored, etc.
Methods Reviewed NEPA documents & tech reports Gained initial understanding of issues at hand Six weeks in the Rogue Basin! Visited Southern Oregon Hx Society & Josephine Cnty Hx Society Collected and reviewed newspaper articles & LTEs Conducted interviews with key informants Read Public Hearing Transcripts & Public Comment from NEPA planning processes Created database, tallied for or against removal Analyzed content to identify major themes
Savage Rapids Dam
History of Savage Rapids Dam Built 1921 - lacked safe passage for fish 1929 – GPID granted water right for 230 cfs to irrigate ~18, 000 acres Never reached that amount of irrigated lands 1982 –GPID reports only 7, 738 acres under irrigation § State of Oregon reduces water right to 97 cfs § 1987 – GPID applies for additional 90 cfs 1988 – 1990 - NGOs protest water rights application § Settlement instructed GPID to study water conservation practices & investigate fish passage option including removal
Savage Rapids Dam con’t 1994 – GPID issues plan to resolve fish passage issues through dam removal Replace dam with pumping system 1995 – BOR releases Planning Report/Final EIS Preferred Alternative: Dam Removal/Pumping Facility Dam Retention Alternative No Action Alternative BUT. . Months later, new GPID Board reneges on removal, launches statewide lobbying campaign! And…Senator Brady from Grants Pass became Pres of State Senate – “Saving” dam becomes state priority!
Savage Rapids Dam For the next DECADE – Political and legal campaign rages forward Driven by “Save the Dam” contingency and Dam Removal Advocates State & Local level, U. S. Congress, Dept of Interior, and federal courts 1997 – Southern Oregon/Northern California Coast Coho Protected under the ESA as THREATENED 2001 – Settlement of federal & state litigation Required GPID to remove the dam 2006 – Funding in place, engineering & environmental analyses complete, contracts awarded, construction begins 2009 – Dam completely removed
Gold Ray Dam
Gold Ray Dam: on the fastrack 2009 – Oregon Statewide Fish Passage Priority List Gold Ray Dam = FIFTH greatest barrier to fish passage Existing fish ladder does not meet passage standards 2009 – Jackson County receives NOAA Coastal & Marine Habitat Restoration Grant American Recovery & Reinvestment Act (ARRA) Feb, 2010 – Draft EA issues Dam Removal Alternative (preferred) Dam/Fish Ladder Rehabilitation/Reconstruction Alternative No Action Alternative
Gold Ray Dam con’t May 5, 2010 – Jackson County BOC unanimous vote to remove the dam Order No. 80 -10 – directs staff to take necessary steps June 2010 – EA clearance version – for Removal May 24 to July 28, 2010 Appeal to OR Land Use Board of Appeals Appeal to Jackson County Hearings Officer Cases dismissed/denied – Order No. 80 -10 not a land use decision U. S. District Court (OR District) over due process. Appellants didn’t have a case. Removal continues, completed Oct 2010
Framework Revisited Source: Lowry (2003)
Applying the Framework Political Coalition/ Decision. Making Receptivity to Venue Change Scientific Consensus on Benefits of Change Low/ Moderate High/Moderate High Low Tolerant to Change SRD Low/ Moderate GRD High Physical Complexity Costs of Maintaining Status Quo High & Significant SRD = Savage Rapids Dam; GRD = Gold Ray Dam (jurisdictions; decision points)
Concluding Thoughts Fundamental changes have occurred but Savage Rapids much more slowly than Gold Ray WHY? Conditions were different Savage Rapids wasn’t always Fundamental; reflected Disjointed Changes for a long time Gold Ray had more pro-change variables in place Lowry’s Framework A way to categorize the process
