THE LARGEST RUN OF SALMON IN HISTORY.... what in the hell are you talking about.. What history book are you reading?? I guess if you are about talking about in "your" life time and you are less than 20 years old that may be true. The big return of fish this year "which is nothing compaired to what it once was" is the result of several good water years in a row... The turbins are only a small part of the problem. The main issue being the large stagnet lake that is now the Columbia river. Water temps etc. You sound like some one who just went on a BPA tour and came out brain washed...
