Is it Hydropower or Salmon in the Northwest?I. Background: I. BackgroundSlide5: A deep-seated conflict: Salmon: cultural icon, mainstay of a fishing economy, central focus of treaties, ESA and Clean Water Act Hydropower: half the region’s energy; vital to NW economy; tied to Canada, California and Southwest energy systems Flood control, navigation, irrigation and recreationSlide7: Lower Snake River draw-downSlide8: Litigation and its aftermath: 1994 court rulings concluded that federal recovery efforts were flawed 1994-99 interim opinion hinted at major changes at dams in 1999 Dam-breaching looks cheaper, easier, more effective than draw-down The dilemma in 1998: no authority for breaching breaching would help only Snake River fish Slide9: The 2000 biological opinion: Avoid jeopardy with federal and non-federal habitat restoration (long-term); tributary water solutions (short-term) Still hinting at major changes 5-10 years out based on monitoring and evaluation Slide10: National Wildlife Federation v. National Marine Fisheries Service: 2000 biological opinion is arbitrary and capricious because it improperly relied on federal habitat programs that weren’t cleared through ESA and non-federal programs not “reasonably certain to occur.” II. Effects of climate change: II. Effects of climate change “Facts:” 3 degrees F higher average temperatures More rain, less snow Higher winter streamflows, lower summer streamflows Spring runoff peaks about 2 weeks earlier About the same annual runoff (Preliminary Results, University of Washington Climate Impacts Group)Historic vs. projected streamflows : Historic vs. projected streamflows Source: A. F. Hamlet, Seeds of Crisis, Water Resources Policy and Development in the Columbia River Basin (University of Washington Climate Impacts Group, February 2002)Historic vs. projected climate: Historic vs. projected climateSlide14: What might it be like? For the mainstem, consider 2001: hot, dry weather chaotic energy markets hydro operations for salmon abandoned upturn in the ocean record salmon returns III. What’s Next?: III. What’s Next? Near term: NWF v. NMFS remand: Is the 2000 opinion void? Shore up habitat programs (with a dash of hatchery supplementation? Flood control bottleneck Renegotiate Columbia River Treaty? Breach dams (which ones)? Jeopardy opinion, followed by exemption process?Slide16: Longer term: Multiple crises overlap with little predictability, sharper conflicts and narrower choices Greenhouse concerns favor hydropower, given current technologies and economics Confusing signals from ecosystems You do not have the permission to view this presentation.
