I seem to recall a few years ago reading that they had identified somewhere on the far side of one hundred factors which were thought to or known to influence populations of salmon in the northwest.
I do know that dams without fish ladders make amazingly good barriers to fish passage.
Can you believe not ONE word about commercial and tribal over-fishing? Duh.
There isn't any mention of how the Sea Lions use the Dams to chow down on the Salmon. There is no mention of the Northern Pike Minnow, Walleye, Smallmouth Bass and other predators, eating the smolts, in the (Dammed) rivers. What about the controversial move of releasing hatchery smolts? And the issue of holding back water, behind the Dams, instead of releasing it to help the smolts flush down the river.

Actually this report supports what the CCA (Coastal Conservation Association) has been saying about the salmon and steelhead from the northwest.
One of the clubs I belong to had Gary Loomis as the guest speaker and in his speech he said just about what this report said. It is the massive overfishing out in the oceans that is destroying our fishery.
He had the figures to demonstrate his statements.
I figure if Gary Loomis and the CCA say it is so, then there is a real high probability that it is so.

Larry -
Interesting article. Thanks for posting the link.

With carefully controlled amounts of ocean fishing and a sudden drop in Sacramento chinook, it is illogical to assume that ocean overfishing caused the sudden drop.
Here is an Article that talks about what the real problems are: http://naturalfoodsmerchandiser.com/...9/Default.aspx

The river I live by has been affected by diking and dewatering of its estuaries, diking and channelizing of its main stem cutting off all sloughs and side channels. Every tree along its entire length has been cut down. Run off from farms, roads, developements, city streets, parking lots and anything else you can think of flowing into the river untreated; containing just about every chemical and polutant you can think of. Both the main stem and tributaries dammed changing the flow, temperature and chemical make up of the river forever. Its fish have been assaulted by nets and over fishing for about a century. Gee, I wonder why the fish are having such a hard time? Its about the habitat stupid.
And the people that live along it can only think about getting flooded. Dumb %&&$, don't build next to the river and you won't have to worry about it!
Same old story.
When the white man first moved to the Skagit Valley he asked the indians where he should build his house so he wouldn't get flooded. The indians told him to build above the high water mark on the trees. So, what did the white man do? He cut the trees down.
What a very narrowly focused article....misses a whole raft of Real Problems...Quote:

Ray,
Your correct! I read information on quite a few sites and there are opinions from the Dams are the cause, predation in the rivers, low snowpack in the mountains, too much water taken from rivers for irrigation, not enough food for the salmon in the rivers / ocean, the ocean temp too high, the American commercial fishing, the Foreign commercial fishing, gene pool problems with hatchery salmon, farmed salmon escaping into the population, bait fish being commercially overfished in the ocean.

Is the Bonneville Power Administration nervous about Wind Farms?: http://www.katu.com/news/33967994.html
