Given the renewed interest in removing the four Lower Snake River Dams to aid in Salmon recovery, I recommend reading these two items, which provide some historical insight with respect to salmon numbers:
1. Chapman, D.W. (1986). “Salmon and Steelhead Abundance in the Columbia River in the Nineteenth Century,” Transactions of the American Fisheries Society, 115:662-670.
2. McDonald, Marshall (1894). Report of the United States Commissioner of Fish and Fisheries on Investigations in the Columbia River Basin In Regard to the Salmon Fisheries, Government Printing Office, Washington D.C.
Chapman’s article contains an interesting graph of “Salmon Catch (Harvest) vs time (from about 1870 to 1970) as well as a listing of numerous other interesting references related to Salmon.
McDonald’s 1894 report states that “there is no reason to doubt- indeed the fact is beyond question- that the number of salmon now reaching the head waters of streams in the Columbia River Basin is insignificant in comparison with the number which some years ago annually visited and spawned in these waters. It is further apparent that this decrease is not to be attributed either to the contraction of the area accessible to them or to changed conditions in the waters which would deter the salmon from entering them.”
To give some perspective, the problem of declining Salmon numbers was noted prior to 1900 and the first Lower Snake River project was completed in the early 1960’s; more than sixty years later.

Is replacing a 45 year old power producing system really a problem???
We 'upgrade' our computers and phones quite regularly; we got to have the latest TV systems; probably buy a new car every 10-20 years; that 30 year old bathroom definitely needs immediate refurbishing; etc......
Seems like a 45 year old power plant has done quite well really...... shouldn't be an issue to upgrade it; should there?????

I think a 'real time test' of the Lower Snake power generation system is definitely in order; and I propose this 'test' be arranged and conducted this summer:
On Thursday, August 13, 2015; shift the entire electrical load from the Four Lower Snake River projects onto other available power supply sources; and then keep the Four Snake Projects completely 'off line electrically' until Monday, August 17, 2015; or if found necessary simply end the 'test' and restart them at any time it is shown that the remainder of the power system can't make up supplying the power the Four Lower Snake projects were generating at the start of the test.
My bet is that the Four Lower Snake Projects absence from the electrical system will be noted during the 'test' and that their presence back 'on line electrically' will be requested before August 17.....
A real time test like the above proposal should provide 'dam facts;' which I do agree are needed here.......

The answers all lie in the statistics:
With an emphasis on the 'lie' part.....
Good statistics well done; or is that done well????
Reading the book will answer the riddle......
The book was written in the 1950's; but some things never change......

One would think Global Cooling would have kicked in by now; what with all those spinning Cooling Fans lining the ridge lines in the distance......
Maybe they aren't spinning fast enough to cool things down.......

There do appear to be quite differing and divergent 'opinions' on the subject:
This US Government report, one of several written during that era, was written in the 1890's; almost 70 years prior to the construction of the first Lower Snake Dam:
McDonald, Marshall (1894). Report of the United States Commissioner of Fish and Fisheries on Investigations in the Columbia River Basin In Regard to the Salmon Fisheries, Government Printing Office, Washington D.C.
I am curious how the removal of these projects will solve a problem, that of declining Salmon numbers, which was clearly noted seven decades before their construction???

A good place to express 'opinions' is to attend a panel discussion on the subject.......
One was recently held in Missoula on the Snake River:
Some will be held on Monday, 03-23-2015; in Moscow, Idaho:
A few years ago, discussions were being held about the Elwha River projects:
As the article subtitle says, "its an exciting time to be a dam buster...."

Wonder if the author of the Factcheck article is somehow related to the person who invented the Internet????
I think they do have the same last name......

10 to 20 gallons per minute running continuously for four months seems like it would be noticeable to someone somewhere in the water delivery system......
All the Watch Dogs must been on Holidays break.......
Where did the water come from???? Pumped from wells???? Supplied by City????
Sure seems like someone somewhere would have noticed four months of high water flows during the winter time.......
