Climate


Work in progress

It has been said that Ocean Conditions has the biggest impact on salmon runs and their health.  Salmon spend about 99 percent of there life in the ocean and their food supply is directly related to the Pacific Decadal Oscillation.  This is also connected to the El Nino effect as well.

PDO = "Pacific Decadal Oscillation"

     At a public meeting in Pasco which was put on by National Marine Fisheries Service they described the " Assessment of Lower Snake River Hydrosystem Alternatives on Survival and Recovery of Snake River Salmonids" April 16, 1999.   I was astounded to learn that the National Marine Fisheries Service has just now started to study the effects of climate and ocean conditions on salmon. This information and data should be complete before any conclusions are drawn or recommendations made about breaching dams.  Today we know that there are more fish going down stream than before there were dams on the Snake and Columbia rivers, the problem is that they are not coming back.   Since salmon spend 99 percent of their life in the ocean, to not study the effects of climate and ocean conditions in this process and consider these factors is another gross error and omission that is so obvious that if shouts out.

      Because of the latest increased salmon returns currently happening, the creditability of PDO ( Pacific Decadal Oscillation), should be confirmed by what happened in 1980 and what is happening today.  The last large salmon return was in 1980, and this year is the highest salmon return since that time, which is exactly 20 years later.

     Probably the biggest factor that is effecting salmon is the "Pacific Decadal Oscillation" and "Conveyor Belt" weather conditions.  This is supported by similar salmon conditions in Alaska and in Canada.  Please refer to the articles, " The Killing of Bears"  and " Fraser River Salmon facing global warming threat" (In the articles area of this page).  There are no dams related to these problems or on Puget Sound.  This further discounts the theory that dam breaching or dam removal will restore salmon.   It is always easier to point and blame someone or something else for problems rather than to deeply study or evaluate all the facts.  In this case everyone needs to also address mother nature in this issue, and it would also appear that fisherman have also neglected to do that.  Please refer to  "Long-term Climate Trends and salmon Population"  http://www.ocs.orst.edu/reports/climate_fish.htmland http://www.ocs.orst.edu/reports/wet-dry.html for more information.  Salmon do good with cool wet weather and they do bad with dry warm weather. 

INFORMATION HIGHLIGHTS:

Decadal climate cycles and declining Columbia River salmon  James J. Anderson, University of Washington School of Fisheries.  
This interaction of climate and dam operations has more than historical significance: by ignoring climate cycles salmon managers may misinterpret the effectiveness of the recent stock recovery efforts, and in particular they underestimate the benefits of smolt transportation. 
Several proposed recovery plans for the endangered Snake River salmon (Schmitten 1995, CRITFC 1995, Williams et al. 1996) directly or indirectly assume that the past twenty years of salmon mitigation efforts have been ineffective, since salmon runs have continued to decline. These plans, to differing degrees, propose to de-emphasize fish transportation and advocate in-river passage using higher flows from storage reservoirs, spilling water at dams, and drawing down the reservoirs behind the dams to improve water velocity and fish habitat.  The premise is that these actions will mimic the natural river conditions that occurred in the past when fish runs were larger.   Whatever the effect of these proposed actions, it is in my opinion, unlikely that they will approach the benefit of a climatic shift back to a fish favorable cool/wet regime. Plans that eliminate beneficial programs, such as fish transportation, will only worsen the present situation.  In a larger perspective the consequences of ignoring the complex and long-term interactions of climatic cycles and anthropogenic actions and focusing instead on simple short term explanations are significant.  In particular, when dealing with endangered species a narrow focus may lead to misguided beliefs on the success and failures of restoration efforts.   It is only through a long term ecological perspective, embracing natural and anthropogenic interactions, that society can assess the actual impact of human activities and realistically identify options and limitations faced when correcting environmental damage accumulated over decades.
