Re: Flooding on the Missouri
Not checking the accuracy of the numbers but your calculation doesn't account for new water coming into the lake.
I may be right. I may be wrong. But there is a lot of gray area in-between.

Re: Flooding on the Missouri
Yes, and for the last couple of weeks, more water was coming into the lake than they could let out.

Re: Flooding on the Missouri
This chart shows how much more rain has fallen in the Northern Plains in the last 60 days over the average--in some cases 300-500 percent over large areas.

Re: Flooding on the Missouri
Good diagram shows the differences between a breach, overtopping, and an overtopping breach on levees.

Re: Flooding on the Missouri
They're not sending trillions of gallons of water downstream for shits and giggles. Obviously water is flowing into the reservoir at rates comparable to what's going down the spillways.
Since the talk was about "empty the entire lake" it doesn't seem to take the inflow into account.You know... I used to think that, surely, the Corps could have released water sooner to prevent this all from happening.
...
So, at that rate... it's only going to take -43- hours to empty the entire lake!
From the NWS in Pleasant Hill:
During the last half of May, the upper Missouri River basin received nearly a year`s worth of rainfall. In addition, the forecast snow melt runoff is 212 percent of normal across the upper portion of the river system. These conditions have resulted in Missouri basin reservoirs across eastern Montana and the Dakotas nearing their maximum levels. Record releases have continued at Gavin’s Point dam located to the west of Yankton, South Dakota. Planned water releases were increased to around 150,000 cubic feet per second (cfs) from Tuesday, June 14th through Tuesday, June 21st (a release rate of 150,000 cfs would fill the dimensions of a football field 156 ft deep in one minute!). The previous high release at Gavin’s Point was 70,000 cfs in 1997.
However, a large heavy rain system impacted much of South Dakota and northern Nebraska from Sunday night, June 19th through early Tuesday morning, June 21st with as much as 6 inches of rain falling across parts of South Dakota. Due to the expected high inflow into several upstream reservoirs the US Army Corps of Engineers has announced increases in the release from Gavins Point beginning Wednesday, June 22nd. They are now projecting releases of 155,000 cfs on Wednesday and a new peak of 160,000 cfs on Thursday, June 23rd which will continue through August. This additional 10,000 cfs on top of the previous record 150,000 cfs will result in an estimated increase in river stages from 0.3 to 0.4 of a foot from Omaha to Rulo, Nebraska...around 0.6 of a foot at St. Joseph...and roughly 0.7 of a foot at Kansas City. Actual stages will depend on tributary inflows. It will still take an estimated 4 to 5 days before the additional water arrives.
I may be right. I may be wrong. But there is a lot of gray area in-between.

Re: Flooding on the Missouri
The inflows match or exceed the discharge rates... my point being... you could have emptied Lewis and Clark Lake months ago ahead of this deluge... it's only taking a couple of days to entirely fill it up again. So, there is nothing the Corps could have done to better mitigate what is happening now.
Re: Flooding on the Missouri
so it wouldn't have done them any good to start releasing immediately when the snow began to melt?

Re: Flooding on the Missouri
Precisely... they could have been releasing the water at full capacity all spring long and it wouldn't have made a difference. What's being released now... just entered each dam within a couple of days prior.
Oh, and don't look now... but the rains over the past 48 hours have resulted in their bumping up the release rate at Gavins Point to 160,000 cfs... and they're projected to continue THAT on into the middle of July.

Re: Flooding on the Missouri
Corps forced to increase water releases on the upper Missouri
http://www.bizjournals.com/kansascity/n ... a=e_du_pub
“Missouri River levels will remain dangerously high for the foreseeable future,” said Steve Iverson, deputy engineer for the U.S. Army Corps of Engineers U.S. Army Corps of Engineers Follow this company ’ Kansas City District.
Releases from Gavins Point will increase to 160,000 cubic feet per second by Thursday morning, Omaha-based Corps Water Management Division Chief Jody Farhat said Tuesday night. Before 2011, releases had never exceeded 70,000 cfs.
.....
But heavy rains Monday and Tuesday in the Dakotas and Nebraska pushed the reservoirs, the river and its tributaries higher, forcing the corps to accelerate the release of water from reservoirs, including two with flood control pools that have filled beyond 100 percent.

Re: Flooding on the Missouri
What will be interesting when this flooding is over will be how the river changes its path. The '93 flooding changed the course somewhat and that flooding was over a shorter period of time. A river always wants to go in a straight line and it will eat away at land to do so. Looking at the map for the river flooding Minot and there are many turns for it. Don't know the lay of the land there but I will assume that river will have more than one course change.

Johnny Rowlands photos of the flooding in Holt County. The Weber Farms is about 2 miles outside of my home town. My step-father and brother worked for Weber Farms at various times when I was a kid.
