OROFINO, Idaho - Officials from the U.S. Army Corps of Engineers say residents below Dworshak Dam on the Clearwater River have little to fear, despite the 36-year-old structure's recent rating as "unsafe or ...

the link to the Times-News is a dead link

anyway, if there are potential problems ahead, then why is the water level rising so high?
I suspect that safe or not, we are at the mercy of 'IF'.
I would like to read a post by the US ARMY CORP OF ENGINEERS, or OSHA DAM & BRIDGE, what amount of metal fatigue and rust, that is affected and surrounds the crack in the dam, is. Keep those innertubes on standby,'JUST'N'CASE'

I read it at some point it said it was leaking at the bottom. Man that would be bad. We have had so much snow this year the dam will get a good work out.

Maybe it's time the US Army Corp of Engineers took out the dam. It's not a natural part of the environment, and puts alot of people in danger.

I read not long ago, that in Port Angeles, WA the dam around there is coming down by 2010. I suppose their water will go into Juan De Fuca. Don't know how that would work from Clearwater Co. to Lewiston.
I am really afraid for you guys up there.

It is interesting, that with every drawdown of the backed up slackwater in the Columbia and lower Snake river, when the water gets to the ocean @ Portland, the amount of fresh water merging with the salt water, it creates a wonderful rain/snow storm here.

Aside from the wonders of it all, our areas' tree farming goals and desires are again put on hold, and a race for whatever resource is on, like an extension of a Natural Disaster, creating more disasters of more flooding in recent years to come. It just brings the quasi-Doomed Doom, more real and sooner than needs to be. How many years of perpetual disasters in the same places,(I am speaking of Hurricanes) for people to realize that you can keep rebuilding back in the same places time after time, but, the consequences of sustainable forrests, do not sustain, only wasted by people not planning to relocate and build in zones that ARENOT in Hurricane Alley. But, this just brings up more questions, as to Nature , Earthquakes, Volcano's, Flood, Fire, Famine, Pestlence, ect. & so on...

History shows, that the corp is for the corp & the large utility company's, and money is at the forefront of their intentions. And that nothing gets done, till people are killed, all when its' too late to do any thing to prevent it from happening. Like a little but many 'god' experiments.(it seems)
On this note, realizing that mankind is truely at the top of the foodchain and the greediest form of living breathing DNA,(I call mankind the largest parasite of the planet) to speculate at the engineering feats of past to modern times, with the scale of plans, that really don't fit in very will with Mother Nature.

There are 10 dams on the removal list, Dworshak is among them. Personally, if Dworshak stays, I believe that 3 more layers are in order for more power production, as well as the most modern largest *In Dam Fish Hatchery* in the world, with a miniture Northfork river on the surface of the tier'ed structure, with always stocked fish, and the worlds larges modern Tree Farm incorperated onto the face of the entire project, to 'blend in' with the natureal existing hills, mountains, landscaping.

hope I did not bore anyone.

I do miss the white water that the river system had, before the slackwater though. Fish liked it too. So did the deer, elk, ect. At least they survided better and didn't fall through Dworshak ice, and drown as often. HABITAT FOR NATURE

not just a tiny slice of habitat for humanity.

You are correct. And, I agree. Exactly WHEN are the corps planning to take the dam down? I think starting this year would be a good idea given it's potential life threatening problems.

When I lived in Orofino, I was told that Washington state benefited from the electricity provided by it, not Clearwater Co., ID. Makes no sense, and neither do the high water bills in Orofino.

I live NW of the Mighty Mississippi River here in the town of Grand Rapids, MN, and "if" we even have a dam, I don't know where it is. Bet Grand Forks, ND might be getting a little antsy by now with all the snow? And, the Red River flows up...not down. They also have a dam, but it is very small, unlike Dworshak, which is big and scary.

No, you didn't bore anybody. But, better order about 4,000 inner tubes! What is the population of Orofino now? With the price gas has been, and going back up, and loss of jobs, I guess that some people have left.?????

You have to consider the dam was also put there for flood control.

November 4th, I took a boat ride up to Grandad Bridge. There is absolutely alot of water up there in the resevoir. Also and ugly ring of washed away top soil at the high water mark. Can you imagine what the bottom of the canyon where original river run? It is a huge meadow of mud , if water were all drained. and left to form its own natural waters to make its' meandering path through the mud. A wonderful place to replant Cedar trees to hold the earth in place.
If the dam is removed, can you see the equivelent of 12-18 times the amount of mass of mud, rocks, ect., more than the mass of the concrete structure. It would be more of a mess than it is left alone, and damming the dam. Thats a thought, build a dam over the dam, 3/4 the way up the old one, and build a dam over the dam beneath the dam, 1/2 the way up, and finally, build the last tier. From the Boat dock up to 1/4 way up, gently sloping, from A road side to B road side, and the worlds gigantic fisheries program inside all of them, but at the heart of it all, is the multi phased generators, for the Steel Mills, when they are considered a reality for the future. Lots a Watts

good idea. That is a valid point and it makes since It would be cheeper than takin it down. It was put there for safety also. Your talking a mile of GUNK.

The Height of the dam is somewhere
http://www.cbr.washington.edu/crisp/hydro/dwr...
around
Dam: Dworshak Dam. North Fork Clearwater River. River Mile 1.9
Constructed: 1973 (units 1-3, skeleton bays 4-6); units 5 and 6 deauthorized in 1990, unit 4 deauthorized in 1995
Owner: U.S. Army Corps of Engineers, Walla Walla District
Normal Operating Pool 1: 1445.0-1600.0 feet
Maximum Pool 1: 1604.9 feet
Powerhouse Capacity:
Nameplate capacity: 2 @ 90 MW, 1 @ 220 MW, 400 MW total
Continuous overload capacity: 2 @ 103.5 MW, 1 @ 253 MW, 460 MW total
Hydraulic capacity: 10.5 kcfs

http://en.wikipedia.org/wiki/Dworshak_Dam
Originally the name was slated to be "Bruces Eddy," but the name was changed to honor Henry C. Dworshak, a United States Senator from Idaho. The dam is the highest straight-axis concrete dam in the Western Hemisphere and the 22nd highest dam in the world. Only two other dams in the United States exceed it in height.
Altitude: 1,581 feet (482 m) above sea level
Height: 717 feet (219 m)
Length: 3,287 feet (1,002 m)
Powerhouse
Two 90,000-kilowatt units
One 220,000-kilowatt units

I used to fish below several dams when I was kneehigh to a grasshopper. Lucky Peak, Arrowrock & Cascade Dams.
When Dworshak was freshly built I was the lucky generation that was able to canoe or raft/dingy/boat float right up to the edge of the concrete to fish in the Clearwater. But, times have changed with every measure of security levels and standard operation procedures over the years. Shure put an end of an era of Wan-a-gons on the river.

there are no immediate plans to tear it down completely,
but,
I believe to be on the safer side of 'IF', would be to draw it down to below the level of the injury/crack, and dry it out, and attempt a salvage first...
then make a decision to abort or second tiering to 3/4 way the height of the dam. and so on.
Since I am not a General of USArmy Corp of Engineers, I doubt that any of my opinions would even be considered.

Hail, just draw it down to the Northfork River and assay the possibilities, while you're at it. consider making a north face addition, with multiple fish screens, and a south face addition with the plan for more exportable electricity, and the internal fish hatchery thing.

YEAH, LETS PUT SOME IRON WORKERS BACK TO WORK
AND THE CONCRETE WORKERS TOO
AND DON'T FORGET TO IMPLEMENT A PURIFIED WATER DELIVERY SYSTEM TO THE VALLEY TOO.

Anyway to make a lake out the area, "if" Dworshak is taken down? I can't locate that info. anywhere so far. I mean make a man made lake, "if" nothing else. Rip, your above idea was a good one, naturally!

they can't take it down it would cause a lot of distruction. It was built for flood control. not just to incorporate power. If they did anything they would build a locking system either a new dam in front or one in front for safety. If that dam goes we are all dead.

I really doubt that the water will rush out all at once, unless something helped it rip, like a dozen or more S&P Futures, or 1-GollyWog

There is alot of water, but I doubt it would breech all at once, it would need help. And there just may be enough crap inside the dam to do it. You would be surprised at what is inside that dam in the way of Military toys. It certainly is not a structure with the powers of God.

I HOPE the Corps. does whatever is the right thing without endangering lives of all of you who live there. In the meantime, I HOPE it doesn't break, etc.!! Maybe, I'm lucky, in some ways, that I live here, for a time...huh? Artic weather at times or not. Much as I just LOVE the Pacific Northwest! Wonder who all and what all in Port Angeles, WA is at risk when their dam comes down??? Guess we'll see between now and 2010..huh?
