How are the dikes holding?  Have their pumps been able to divert local runnoff from recent T-storms?  From what I could tell, the city has been able avoid a direct hit from big thunderstorms as of late.

I say to hell with that pot o' gold.

,

I assume you mean Omaha?  We have dodged several bullets - storms - but a tremendous amount of water fell on the Big Sioux north of us just two days ago and the rains on the North Platte out west yesterday were rediculous 4"-6".

So far the dike and flood wals built in Omaha before the Dams were constructed shortly after the 52' flood seem to be holding.  They have brought in huge pumps on flatbeds just in case.  Watch Omaha tonight, we are supposed to get storms for the openner of the CWS...Yikes.

Actually, I was referring to Bismarck.  Looks like you folks have your hands full down there too. 

Something tells me that with western ND having an abundance of well paying jobs, and high/dry ground to build on, we will be seeing even more people in the next few years.

New forecast has Oahe and Big Bend releasing 160KCFS. That will help the backwater effect at Bismarck.

Man, possibly even folks from SD, and Nebraska will be flocking to the oil fields.  It's inevitable.

Yeah, pretty good amount of inbound water from everything below Garrison, so in order to hold steady, Oahe will have to boost output.

Things looking better at Peck and Garrison, they adjusted release on Oahe, Peck, Bend to blow out all the rain.

 That inflow from the north, though, is finally reaching Lake Sakakawea.  Today inflow into Garrison Dam is 192,000cfs and the outflow is 150,200cfs.   I was up at the Dam last weekend to see where it all sits; only 12" of freeboard.   That isn't much wiggle room, people!

The ACoE will have to increase the release levels in order to keep up with all of this excess rain & snow melt.  I cannot fathom how they couldn't!  The river level in the Bismarck area is still lower than anyone expected.  There is buffer room to release more if you really consider the logic.   Problem is, does the ACoE use logic??

So there are a lot of recent articles/blog posts blaming the Corps for not releasing water sooner/faster. Has anyone calculated some predictions for what the average release would have had to be from Garrison in late March, April, or May in order for current releases not to be as high as they are now?

No, but late one night I did the math on CFS which = 7.86 gallons.  At 150,000 cfs (soon to be 160,000 and likely 175,000) we are talking about 71 million gallons per minute, 4.24 billion gallons per hr and 102 billion gallons per day.  That's OFFICIALLY, a B%$#H load of water.  The Corp states that is the equiv. of emptying Gavins Point Dam each day.  I know they have had higher flow rates for two years because we have been unable to waterfowl hunt on the river due to high flows each Fall/Winter 2009-2010.  I guess the flows should have been a little higher.

I have to agree with you, if you look at the forecast through mid July the best days are only going to be showing a release of 13K CFS more than whats coming in and there are several days where the income is 20-30K more than what being released.  I hate to be the one to say it but the only way to get ahead of the incoming flows is to increase the releases to atleast 165KCFS even if it's just for a few days.  I just don't see how the lake will go down otherwise.  Does anyone know if these forecasts include additional rainfall that may occur?  Its a scary deal.

A link to an article about the Corps and current flooding. Might have to copy and paste it to address bar as I am unsure I linked it correctly.

Well shiite.  That's gonna cost me $0.50.

Small price to pay to get the water a little lower!

It seems like with the corp and nws that the crests are almost always lower than the predicted.

Think of the weight of the water going through the dam right now...amazing...

1 cubic foot of water hold 7.48 gallons.  One gallon of water weights 8.34 pounds. 

150,000 CFS equals 9.36 million pounds of water going through the dam every second.

This is a VERY good thing.  Over estimation creates over preparation......

crests predicted correctly would be the best though. Probably some situations(maybe not necessarily this flood) where people said the heck with building a dike because the over exaggerated crest made attempting to save their home futile, yet the lower water resulted in minor damage that a dike could've prevented. Or with different areas flooding at the same time, resources could've been given to other areas that actually needed them.

 from the above link.  Interesting depth profiles along the Missouri.  I'll be the first to admit that I didn't believe the earlier reports of holes this deep, really tough for me to get my hands around the physics of this without the river banks falling in on themselves.  It'll be even more interesting to see if these holes last through the entire event or if they start to fill in as the water levels decline.

p.s.  I really, REALLY, hope all that damn riprap that has been ripped off the shorelines falls into one of these holes.  Otherwise it's going to be a damn minefield out there after all of this.

I just checked the release from Garisson Dam and it is down to 118,100.  are they still lettign water over the spillway?  Is Bismarck in recovery yet or is the water still too high?

Ehhh, where did you get the 118,100 number? 

Today, the releases are supposed to be 120,000 cfs.  Mind you, the gates are anything but a fine-tuned valve.  So the actual number is always going to be +/- a few percent.  But numbers with such specificity that vary from the 3-4 week forecast generally tends to imply the USGS has measured the downstream flow.  Hence my curiousity.

Never mind, I found a reference to it.  It was listed as the "daily average flow".  The reason it wasn't a more round number is because there was a shutdown yesterday as they inspected the tunnels. Hence the "average" value for the day is less than the listed value for the day.
