Missouri River rise

Why is this not mandatory building code along any flood plane anymore? In a lot of places if one wants to build in a flood plane this is your only option.

It basically is! The one real difference is instead of putting first level blowout panels in the people here just build up giant dirt mounds to put their house above the flood zone.

The 5-10-20-50-100-200-500 year flood zone? Where should we start?

Somewhere flooding is within your own control, and not the hands of others with too much political and economical pressure swaying them this way and that.

My point exactly!Thumbs Up

I'm assuming that the sudden 3000 CFS drop was probably linked to when they took the Manuel reading yesterday? Does that sound plausible to you? I for one have no problem with any of these numbers I'm just curious on the technique used to get them all and how they refine them.

Side note that might interest you is that for the second time in two years the aquifer appears to be running backwards.

The flow measurements are all human collected, granted they use a lot of high tech stuff nowadays.

Stop referring to it as a "drop" in flow, it's simply within the accuracy of the measurement. There's nothing to be gained by thinking there's actually 3k less cfs in the river, or more for that matter.

FWIW, between 9 PM last night and midnight, the river in Bismarck actually went down an inch or two. Saw it with my own eyes.

Well you can call it whatever you want but you will find most people generally will call this a drop because well it's sort of you know is a sudden and unexplained drop! It's also interesting now that it's consistently several hundred CFS below what they're letting out not to mention the several tributaries between here in the dam.

We're supposed to have a big storm overnight tonight. What would a quick 5" dō?

Without looking, I would guess the equation for the stage-rating curve, which generally goes in the form of "y = mx + b" has been shifted by updating the "b" due to the measurement. This is common, but until someone tells me the physical process by which the river is now losing a couple thousand cfs, I'd suggest the "drop" is not real. Outside of washing machines and dryers, things don't just disappear in real life for no reason. The same organization that is measuring the flow at Bismarck is also measuring the flow immediately below Garrison Dam. Where they maintain there's 60,000 cfs coming out of the dam.


In the initial run up to a new high water mark, there is discharge water lost that is lost to what's called bank storage (water going into the bank and near shore pore space). This doesn't seem to fit that kind of water loss as it's too much and is usually only really observable for the first few days before a new equilibrium with the flood plain aquifer is reached.

I would hazard a guess the true cfs in Bismarck is right around 61,xxx.

you all talk a a lot about the river level in Bismarck but I noticed that on the 3 week release forecast Oahe is suppose to rise a foot a week for the next three for a total of 3.5 by the middle of July. As a 3C whitetail doe hunter what will this mean for the prime whitetail habitat south of Bismarck and Mandan along the river. Graner Flooded? Little Heart? and areas south?

 

[dean nelson]

McLane bottom started flooding the last couple days and much of little Hart is flooded toward to south end. Apple creek bottoms is about 50/50 water land but unlike the others hers is primarily High River Flows there so once they drop river so will she where the other ones are caused more by the back up of water on Oahe with a bit of high River flows added on top. At 1616.5 much of McClain bottoms and Greiner bottoms will be flooded as in years past.

Think about this. People in LA are smart enough to build their homes 3-4' above the ground. And those are people with no teeth and are married to their sisters. kidding.

 

[Migrator Man]

MT is getting pounded today. Not looking good for an already over saturated area.

 

[guywhofishes]

holy stationary downpour on the west end of sak in the last couple hours of radar

 

[Achucker]

GULP!:;:help

 

[tikkalover]

They just posted a flash flood warning for Indian Hills Resort.

 

[Trip McNeely]

is the radar broken? i got home around 8 and the same cell over the west end hasnt moved. .... not good

 

[espringers]

It ain t broken. It's getting completely piss pounded.

 

[Obi-Wan]

It's a good thing the corp has left enough room in the lake to handle events like this
