Doesn't look good for lower water anytime son, Great falls is now flooding.

Great Falls on Wednesday.

That's on the Missouri, the problem for Williston and Sakakawea is/has/will be the Yellowstone.

Yes but if you go to the site it shows what the blue and black dots represent.

I actually hope it doesn't get much worse as far as outflow, I think if we actually flood again the Corp may get enough pressure that they have to start drawing the lake down further ever year. I don't want that to happen, so fingers crossed we don't go above 75,000cfs.

I'm stinking with this guess. I still don't think it is out of the question. I know you didn't think this was possible before Allen, do you still think so or have you changed your prediction?


Musselshell is flooding too it looks like.

I would have to think that 1853.5 is still too high of a guess. It would take another couple weeks of heavy rain in MT to do anything like that.

I could be wrong but the last time I checked the Missouri River flows into Williston & Sakakawea with a short stop at Fort Peck, which is full so unless they moved the river it is part of Williston & Sakakawea problem.

These are not even remotely similar to each other!

And I mean dear Lord save us from the major flood,,,,, errrr wait I mean moderate flood ahhhhh.... hang on a sec I mean I guess minor flood rolling through great falls right now!

 

[Obi-Wan]

Dean you are forgetting we had a later snow melt this year than in 2011 so we are a couple weeks behind

These are not even remotely similar to each other!

 

[dean nelson]

If you can't fathom the difference between this year and 2011 I would suggest you take one quick look at the Souris River! Remember it wasn't the snow melt in 2011 that took us out it was 1 years worth of rain in two weeks over Southern Canada and Montana that caused most of that flood. So barring that sort of event happening again they are not remotely similar.

Don't you guys know the real reason for the releases being done this way? Two words, pipping plover..... they couldn't flood their habitat on the Missouri because how big of a travesty that would be....

Musselshell river in Montana was near records and once it hits the Yellowstone there is nothing left to hold back that flow. Bismarck needs to hope for no more big rains this summer. The difference between 2011 and present is we had much less water coming into the system from Nd, and this year it's been mostly flow from the mountains and rain in central Montana.

Well put a fork in Merryweathers she's done. Misty looks to have just enough clearance that she should still be good to go after she peeks as long as this is the peak. the area to the left of her in the grass will be flooded but the ramp itself should be manageable but she'll be stretched right to the limit.

Not saying this is another 150,000 cfs like 2011 what I am saying is that we are not done with 60,000 cfs any rain in the upper reaches now will result in increased flows. The COE does not allow enough storage to allow for much more than an average year and that has put us at a point where a major storm could cause serious flooding issues. The COE should never let it get to this type of situation and could be accomplished by dropping the lake maybe 5 feet or so going into the winter which would increase their storage. These excessive flows cause irreversible damage to the river banks and adds sediment to the head waters of the lakes.

The snow runoff is about done, and this year just didn't have the Snowpack of 2011 or even 1997. They already drain the lake to 1837 every year which gives them 17' if room to work with. If they drained it another 5-10 feet like the whiners think they should, the damn thing would be dry if we got into even a 2-3 year dry cycle. 1 flood in 65 years of the dam, this year likely wont even hit minor flood stage. NO CHANGE NEEDED!

take a look at this map and tell me the runoff is about done.

That map literally has nothing to do with remaining snow. That is just the short term current streamflow for that day compared to the 30 year average. One large rain could jump everything up on that map and have literally nothing to do with snow runoff. Here is the map showing remaining snow water equivalent, notice how this year is bottomed out. Also notice how 97,11 had more water equivalent and a longer runoff. Hell this years Snow melt as actually done sooner than average.

Here's Meriwether's and Misty.
