the logical answer is to build a true aux spillway over at the hill by the parking lot. They could complete the spillway and connect to the lake during low water. Then they could repair the original spillway at leisure.

Yah, I agree, that's probably what will actually happen.  But how cool would it be to see that spillway launching 100k cfs off a ramp down to the river 400ft below.

I have not read any since they started dropping bags of rocks with helicopters.  Have they cut the spillway flow to get a photo yet?

Any other excitement since the (first?) evacuation?

What about a ramp to cause the rushing water to jump over the damaged area of the main spillway?   
I doubt they'll do it, but I was thinking that that would be an awesome long term repair to the broken main spillway.  Build a ski-ramp type feature similar to what's there at the bottom of the broken spillway, just launch water out and off in the future.  Only problem is the water still has a long way to fall after that, but if it doesn't make it over to the opposite bank then who cares, just is going to hammer down on bedrock that's all mostly exposed now anyways.

How about we do not give them another excuse to run the dam up past flood control level when they already think that is fun?

That comes from the operations manual IIRC. Some body will correct me if I'm wrong. It is the ideal level for flood control and water storage. The assumption being the hydro is running and spillways set according to pool height.

Yeah, 850 was announced several days ago but completely impossible in the time frame they gave.  Because of the drought they have been trying to keep it as close to 850 as possible so the feds don't yell at them but they will let the lake fill up a lot higher than that during "floods" and then slowly draw it down.  I've seen the peak elevations posted here for the last 7 years or so and it went way above 850 each year, yet last year was the only year they opened the spillway.  

In the one report last year they said they opened the spillway up to just 6,000 cfs and that is when it tore holes in the spillway.  It would appear no one thought to do a complete inspection of the spillway after 5 years of not running and the first time a light flow does go over it the thing crumbles.  Nope, they just slapped a couple patches down and called it good.  The epitome of how state workers operate.

Then dose all the blisters with quality white vinegar.  There is just a mild sting but the itching disappears almost immediately.  I had poison ivy for 8 months last year.  A place I bought was covered in it.  I've beaten a lot of back but it is still everywhere in the brush.

Interesting information.
Were you involved with the tear down and relocation?
That Krupp bucket wheel excavator system ended up at the Centralia, WA coal mine where it was used for about 25 years or more for pre-stripping coal seams.
It was used in 2 different pit areas as I recall.
I started work at the mine when it was in the second area and spent many an hour keeping it maintained and operating.

My guess is that a ski jump at the current break in the spill way could be a temporary repair to the main spill way that would enable them to build a new spillway.  I'd think that the time to construct a temporary jump would be shorter than the additional excavation and potential blasting work required for a complete new spillway.

The other thing I was wondering was the auxiliary gates near the e-spill that were never finished.  With modern equipment I wonder if those could be connected as a new diversion tunnel.  The challenge there would of course be figure out how to do it if the lake levels are above the inlets.

Well... right now it will take ~6hours to drop the water level 1ft.

Edit- At least the storm they were expecting Wed night/Thursday was pretty much nothing...
Unfortunately, the storm hitting tomorrow is worse than they were expecting.

It is the only way left to get water out of the dam. They are being careful with it. Lol.

It was at flood control before they started wondering about how to get water out of the thing besides the capitalist turbines, before the rain, before the snow melt.

there is not a dam thing wrong with the Espill as it sits.

Build a new auxiliary spillway next to the hill so the original can be repaired

I disagree.  It's not anchored in place in any way.  Even if the rock underneath it is fine non fractured rock... it's just sitting there on top of it.  So it can and would be shifted off and breached if it were used for any decent amount of water.

It needs to go deep and get keyed into the good rock down there... and you aren't getting down there without removing the old one first. 

Building a temporary emergency spillway while you replace the current one seems like wasted effort... just repair the bypass tunnel and use that for emergency situations while you replace the Emergency spillway.
