I might have to question that "food for though" going from "... less than 500 chinook in 2004" to now would be one hell of a recovery? Not to mention that would also be one hell of a return ratio?
"Chinook salmon. Despite concerns regarding historic estimatesand the adequacy of current. assessments, the available data suggest thatchinook populations were formerly much more. abundant than now, and that populationabundance has been low since the mid-1970s. The data show a decline from 15,000in the 1950s to below 500 in the mid-1980s and 1990s_ Enhancement byTenderfoot. Hatchery had increased chinook escapements to the Squamish watershedby the mid-1990s, but relative abtmdances have remained below 1,000 chinook forthe watershed between 1997-2000, and were above 1,000 from 2001 -2003 before decreasingto less than 500 chinook in 2004.
"It is thought that enhancement chinook stocks by theTenderfoot hatchery resulted in a shift from stream-type chinook to ocean-typechinook in the 1980s.
