Looking More at Data

First a return to the Salmon issue:

• An Example of a data driven process
• Paying for Salmon Recovery
• Automobile pollution and Salmon Immune systems
• Important role of El Nino
• Real time data collection
• Fishing Technology in Alaska
• Notes from a 50 year Alaska Native

The above documents and data strongly suggest that a significant reason for Columbia river salmon decline is due to increased harvests in Alaska and Canada.

This is likely a reflection of where the Salmon are and this is strongly coupled to decadel climate changes in the Alaska-BC-PNW region.

This implies, that at any particular point in this region, over timescales of 50 years, salmon counts/catches will be cyclical in nature.

So, be careful what you are told without being allowed to see the larger picture:

World Salmon Harvest

	Graph shows total salmon catch off the coast of North America (including Alaska).
Decline of In-River catches which is frequently used as the "best" indicator for overall salmon decline in the Columbia River System:	Implication is that increases in ocean catch are directly responsible for decreases of in-river catches also shown.

Power to replace Salmon Killers What are the options to finding 15,000 MW of power, continuously delivered, at 4-5 cents per KWH?:

• Build 12 Nuclear Reactors along the Columbia
  
  
  
• Build 10 more Coal fired Steam Plants Bring the Coal in my rail Cost to the consumer would be 15-20 cents per KWH. An Example:
  The Centralia Steam Plant is the single largest producer of sulfur dioxide in the state (WA) and is the second dirtiest producer of electricity west of the Mississippi.

  Its capacity of 1340 MW is vital to the PNW and hence large State funds have now been allocated for pollution reduction. Consumer ultimately pays for this.

  
  
  
  

• Place 60,000 wind turbines along the Oregon Coast (that's about 150 turbines per mile
  
  
  
• Develop a 100x100 km PV facility + battery farm for Energy Storage which country in Eastern Oregon or Washington do you pick to "pave" over?

Is there really an acceptable alternative?
