So are they smart enough to get ahead of it this winter?! ;:;banghead


Corps: 2019 Missouri River runoff could set a record


Runoff in the Missouri River Basin in 2019 could set a record, rivaling the historic max set in 2011, when major flooding hit the Bismarck-Mandan area.


U.S. Army Corps of Engineers personnel from the Missouri River Basin Water Management Division hosted a water management meeting Tuesday night in Bismarck that drew about 200 people. The meeting came as North Dakota farmers have grappled with record-setting rainfall and a historic early October blizzard that have ravaged the harvest reason.

An Oct. 1 Corps forecast projects 61 million acre feet of runoff in the basin this year, more than 2½ times the average of 25.3 million acre feet and the highest in 121 years of record keeping.

"If this is realized, it would equal what we saw in 2011," said Kevin Grode, team leader for reservoir regulation.

Flooding that year forced the evacuation of nearly 900 homes in Burleigh and Morton counties. At one point in June of that year, more than 1,200 National Guardsmen were fighting the flood in the metro area. The flood fight efforts lasted until late July, and the river stayed at flood stage until mid-August.

Burleigh County and Bismarck that year used nearly 11.3 million sandbags, and Mandan and Morton County more than 2.9 million, according to the state Department of Emergency Services.

Monthly runoff above Sioux City, Iowa, has skyrocketed above average since March, when an intense "bomb cyclone" struck Nebraska and South Dakota. Snow melting into runoff and above-average precipitation since May also have contributed to the record wetness.

September 2019 was the wettest on record for North Dakota, according to National Weather Service hydrologist Allen Schlag. August and September 2019 came within 1/20 of an inch of breaking the record for the same time period, set in 1900, he said.

"And quite honestly, when October is done shaking out, I already know we're well above normal for the month of October, so we're going to continue this wet cycle, so to speak, well into October," Schlag said. "When it's going to end, that's always the really tough question."

October runoff in the basin is estimated to be about three times the average. November and December are estimated to be twice the average, Grode said.


"This last year has been extremely wet. In some cases, record wet," he said. "We're seeing a tremendous amount of rainfall in our basin over the last 12 months."

North Dakota and the northern Great Plains have a slightly above-normal chance for above-normal precipitation this winter, according to Schlag.


"That's largely based on trends," he said.

The Corps took questions and comments from people in attendance, including Laura Ackerman, investigations section chief for the State Water Commission, who urged the Corps to remain in touch with state and local officials about flooding concerns, such as monitoring ice jams and winter releases from Garrison Dam.

"Given the saturated nature of the basin going into winter, we feel that basin monitoring and the resulting forecasting abilities will be of utmost importance for the winter and the spring," Ackerman said.

Mike Gunsch, chairman of the North Dakota Missouri River Advisory Council, urged the Corps to maintain communication about the basin's runoff and related risks.

"Understand the lack of information tends to feed rumors, and some are legitimized by how they are shared," Gunsch said.

Fred Rios, chairman of the Captains' Landing Township Board of Supervisors, said he'd like to see no-wake zones on the Missouri River and continuous flow until the river freezes. He hopes to avoid a scenario like 2011, when residents around Captains' Landing Township banded together to sandbag the small community on the river's western bank.

"I hope we don't see that at all," Rios told the Tribune.

They've got all winter to let water out. I wouldn't shoot a flare down river, yet....

They have been dumping water as fast as they can since June what more do you want from them?

You build houses in stupid places, you win stupid prizes... Course our tax money will bail everyone out again when it floods. Whoda thunk it?

From today's (10/23/2019) Minot Daily News:

Lake Sakakawea in decline as outflow exceeds inflow

Sakakawea Shoreline.jpg
Kim Fundingsland/MDN Only the top portion of this beaver lodge was visible earlier this year. More of the structure has emerged as the water level of Lake Sakakawea continues to drop. Note the tiered shoreline adjacent to the beaver lodge. The photograph was taken Oct. 20 on the Wolf Creek arm of Lake Sakakawea.

RIVERDALE – More and more shoreline is being exposed all along Lake Sakakawea as the U.S. Army Corps of Engineers, the agency charged with managing the reservoirs on the Missouri River Basin, continues to prepare the reservoir for runoff next spring.

Releases through the power plant and operating tunnels at Garrison Dam have been 48,000 cubic feet per second for several days and are slated to continue at that rate into November. Lake Sakakawea stood at 1,843.82 feet Tuesday. According to the Corps, outflow from Garrison Dam, which backs up Lake Sakakawea, was 48,300 cfs Tuesday with inflow measured at 29,000 cfs. Lake Sakakawea has been dropping approximately one-tenth of a foot per day.

Given the current conditions, Sakakawea is expected to drop to 1,842.6 feet by Oct. 31. The annual goal for the reservoir is to be at 1,837.5 at the end of each February. Corps’ projections have Lake Sakakawea dropping to 1,839.5 feet by the end of November with the expectation of reaching the February mark.

All three upper Missouri River reservoirs have seen very high amounts of water pass through them this year. Runoff for the entire system, spring snowmelt and rainfall this summer and fall, has been calculated at 61.0 million acre feet. If realized, that would equal the highest runoff in the history of the system.

Fort Peck reservoir in Montana, Lake Sakakawea and Lake Oahe which originates in South Dakota, are all below what is considered their exclusive flood control zones and are approximately at the midway point of their annual flood control and multiple use zones. All three reservoirs continue to discharge more water than they are taking in.

On Monday Fort Peck was a 2,241.5 feet with a Feb. 29 goal of reaching 2,234.0 feet. Fort Peck was discharging 15,000 cfs with an inflow of 9,300 cfs. Lake Oahe was at 1,613.3 feet Monday with outflow of 62,000 cfs and inflow of 51,700 cfs. The February operating goal for that reservoir is 1,607.5 feet.
A very wet fall has spurred concerns about the effect abundant soil moisture conditions will have on the snowmelt next spring. The amount of runoff next spring will be dependent on a variety of factors, including soil moisture conditions, the amount of snow that falls throughout the basin this winter, the speed of the melt and rainfall throughout the drainage in early 2020.

It's bigger than that. What do most modern cities and civilizations of yesteryear have in common with one another, location wise?

The outflow from Garrison dam has been nearly double all summer. I should think that they're doing what is prudent. Granted, we can't predict mother nature, but I think it's all being handled. And yes, I do live in low-lying South Bismarck.

Was down in Omaha last weekend...water levels high everywhere in between. Not sure how much more they could have pushed thru the system the last 5 months. Those folks south of us dealing with it too...

Well for the most part you're not questioning anything you're just being Captain cut and paste! But getting ahead of it in winter is what's known as draining the goddamn thing in summer and fall because once she freezes their hands are tied they cannot pump up the flowe's anymore than what the river ice can take!

;:;bowdown



and, Captain cut and paste would like to share:

Lake Sakakawea has dropped over 8 feet since its high this summer with another 6 feet to go before March 1. Based on current trends, they should reach this goal. The Corps recently increased releases slightly from 46,000 cfs to 48,000 cfs to draw down Sakakawea a bit faster as there are some limitations on the volume of releases from Garrison Dam once the river freezes over. This is due to channel degradation (i.e. buildup of sediment from Lake Oahe) south of Bismarck which could result in an increased risk of ice jams if they go over 27,000 cfs after freeze up.

Releases will remain high until the end of November range. Around the first week of December releases will be dropped to about 16,000 cfs until the river ices over. During the freeze in process the river level will rise (which is normal every year). After it is iced over, it will drop and then the Corps will increase releases to 24,000 to 27,000 cfs until spring.
