It all depends on what your definition of "clear" is!
Here's the evil!
It will take at least 2-3 weeks more for the Cowlitz to clear if Tacoma keeps generating power at around 7500 cfs (my best guess). Now when Tacoma increases generation, say up to 10,000 and over (max is about 13,000 cfs) they begin to draw silt from the bottom of the dam. It's being caused by 30 years of silt being built up and deposited in front of the dam and is not likely to change anytime soon.
The really bad news; it appears to be getting worse every year now, and its quite possible that it may be becoming a common condition that we may see all winter long in the future when we experience high or full generation conditions.
I wish that I am wrong, but so far it's not turning out to be that way. Maybe Salmo or someone else who has reliable knowledge of how the operation effects this condition can paint a brighter more pretty picture for the future. It's a crime that WDOE failed to address this issue before Tacoma was given their 401 Permit (that's what happens when you fail to ask for public commit). Since Tacoma was not required to monitor the "turbidity" that they pass through there project, there was no way to support any claim at the PCHB hearing to prove that Tacoma was causing these conditions to worsen by how they were operating there projects.
In my opinion, I think water conditions will get worse long before they get any better when it comes to "how Tacoma" will be operating there Cowlitz Projects in the near future. All one has to do is look at the flow charts of the past, and compare them to how Tacoma is running there Cowlitz Projects now. The flow charts show how Tacoma has released flows for over the past 30 years of operation. Take a good look at the Mayfield flow gauge and you can see what I mean!
