RED RIVER FLOODING ... AGAIN !

the RED RIVER is flooding again and is expected to reach - perhaps even excede - the levels of the 1997 "flood of the century" .

Blame the Ice Age glacial lake that left the river in a flat, wide valley.

Stick a river that flows north into one of the flattest stretches of land on the face of the Earth and what do you get?

Trouble.

That is why folks in the Red River Valley seem to spend spring after spring stacking sandbags, watching the skies and worrying about frost depth, rate of melt and ice jams.

In a region that slopes inches per mile, all it takes is a rapid thaw or an ice dam to send the meandering Red River over its banks and put miles of the valley under water.


grand forks , n.d. is again expected to be flooded .

"It's like taking a glass of water and pouring it on the top of a table," said Kevin Dean, public information officer for the city of Grand Forks, N.D.

"The water just goes everywhere. Everything's flat. That's really hard for a lot of people to understand. But it's just so flat that when it floods, it has everywhere to go and there's nothing to stop it."

It's been that way for nearly 10,000 years, since glacial ice last pushed south across parts of North and South Dakota and Minnesota, creating a "very gentle bowl shape" where the states meet, said Adam Lewis, an assistant professor of geoscience at North Dakota State University in Fargo.

meanwhile , water officials to the north in manitoba , are confident that the billion dollar diversion projects undertaken after the disastrous 1997 flood , will prevent widespresd flooding here .

Despite three days of precipitation in the Winnipeg area and much of the Red River Valley, Manitoba is not raising the level of its flood prediction.

Manitoba Water Stewardship spokesman Steve Topping told CBC News Wednesday that a level on par with that of the 1979 flood is still being forecast.

'Runoff is occurring quickly there and will contribute to Manitoba's flooding, but we're only seeing 1979 flood levels because our snow pack is lower.'
"Steve ToppingSouth of the border, in Fargo, N.D., however, officials are predicting river levels will be as high as 12.3 metres " above the devastating 1997 crest of 12 metres " and a record level in the area.

That crest is forecast to occur Sunday. The crest is anticipated to arrive in Winnipeg between April 12 and 17.

Topping said there are a number of reasons why the predicted levels for Winnipeg are lower. For one thing, the Red River in North Dakota has less capacity and the Fargo region had much more snow this winter, he said.

"Runoff is occurring quickly there and will contribute to Manitoba's flooding, but we're only seeing 1979 flood levels because our snow pack is lower, Topping said. "And the river channel has much greater capacity [to hold the water] here in Manitoba."

the red river flood as described by some early visitor to the area :

Quote:
"The forts now stand like a castle of romance in the midst of an ocean of deep contending currents, the water extending for at least a mile behind them, and they are thereby only approachable by boats and canoes."

Francis Heron, describing the Red River flood of 1826

as the red river is rising , ice jams are being blasted in the hope of keeping the flooding under control .

BISMARCK, N.D. - Demolition crews blasted chunks of ice near a huge ice jam in the Missouri River on Wednesday in a bid to open a channel, like pulling out a giant plug to drain a flood threatening the city.

"We are cautiously optimistic," Bismarck Mayor John Warford said after explosives detonated about 500 feet of ice just south of the jam. He said officials would have a better assessment Wednesday night but that water appeared to be moving.

Water backing up behind the dam of car-size ice blocks already had forced the evacuation of about 1,700 people from low-lying areas in North Dakota's capital city.

is FARGO going to be under water again ?
the "red river" rose above 40 feet this morning it could possibly top 44 feet over the weekend . emergency dikes are being built to contain the river but since the ground is water-logged , water is beginning to seep in under the sandbagged dikes .

FARGO, North Dakota (CNN) -- The Red River rose to 40.2 feet early Friday, breaking a 112-year-old record and creating a quandary for emergency officials who can no longer rely on historical data to guide their response.

Hundreds already have evacuated Fargo neighborhoods, hospitals and a nursing home. Officials across the Red River in Moorhead, Minnesota, also were urging residents to leave.

The river topped the 1897 record of 40.1 feet about 4 a.m. CT (5 a.m. ET), said National Weather Service spokesman Patrick Slattery in Kansas City, Missouri.

"It's expected to continue rising," he said. Forecasters have said the river will crest Saturday.

Record levels for the river mean uncertainty for officials and volunteers who are scrambling to mitigate the flooding in the area, Slattery said.

on the canadian/northern part of the red river some native reserves will likely have to be evacuated from locationns just north of the U.S. border .
since the melting is being slowed down by colder temperatures , there is optimism that winnipeg will be spared flooding in excess of the 1997 levels .
in the meantime , the canadian army has readied troops to assist local authorities .

Thursday, around 850 people from Riverside and the Roseau First Nation reserve, both just north of the U.S. border, were told be ready to evacuate their homes on short notice.

Ice jams choked the Red River, backing up water and causing flash floods in communities north of Winnipeg on Wednesday and Thursday

@hamburger,
Those Fargo numbers are even higher than reported six hours ago. Not good.

@ehBeth,
I simply can't understand why people insist on building in flood plains. I'd hope they smarten up but they never do.

i imagine that most of the houses were buillt after 1900 but before 1997 . people assume that they are safe and don't easily give up their homes - particularly if they don't get any compensation whatsoever - not much differnt from san francisco , hurricane prone areas , vancouver (which has been lucky so far ) .
maybe if we all lived in big trailers , mowing would be much easier .
(wouldn't mind "moving" our house to myrtle beach from december to end of march <GRIN> ) .

@ehBeth,
In reality, everywhere is a flood plain. 10" of rain in 24 hours can flood any low lying area.

Much of the flooding around the Red is actually overland flooding which further complicates the issue. Not only of protecting from flooding but also in forecasting the river's crest.
