In de Verenigde Staten hebben de dammen langs de Mississippi-rivier voorlopig stand gehouden in de strijd tegen het wassende water dat na de overstromingen in de midwest verder zuidwaarts rolt. In Californië lijken de bosbranden dan weer onder controle.
Waterpeil stabiel
Verschillende peilmeters in de staten Illinois en Missouri bereikten de voorbije dagen hun hoogste stand, maar de dammen slaagden erin het water te trotseren. Voor de volgende dagen verwacht de Amerikaanse weerdienst sporadische zware regenval, het waterpeil zou evenwel niet meer gaan stijgen.
Branden bijna bedwongen
Aan de westkust, in de staat Californië, helpen dalende temperaturen en zwakker wordende winden de brandweer de honderden bosbrandhaarden te bedwingen. Een brand in het bekende wijnbouwgebied van Napa Valley zou volgens de autoriteiten voor 35 procent onder controle zijn.

Forecasters Predict More Rain On The Way As Soldiers And Firefighters Struggle In Missouri
Justin Lackey sits on his stairs and looks at the floodwater from the Mississippi River surrounding his house Tuesday, June 24, 2008, in South Shore, Mo. The house was recently raised up so it has stayed mostly dry even though it is surrounded by water.
Torrential rains flooded parts of Missouri as weary soldiers and firefighters struggled to reinforce levees and avoid further damage in a region taxed by days of flooding and storms that have killed two dozen people in the Midwest. Forecasters were nervous about storms expected to hit northeast Missouri and central Iowa on Wednesday and Thursday, said National Weather Service meteorologist Mark Fuchs. "It'll keep water in the system. That's for sure," Fuchs said. "That could turn the river around. That could lead to higher crests." Some roads were flooded in the northern and western parts of Missouri. Six homes were evacuated in Linn County, about 100 miles from the Mississippi River, emergency director Jamie Stallo said. Stallo said no injuries were reported, and the floodwaters were beginning to recede Wednesday morning.

Flooding in the American Midwest in the last couple of weeks has killed 24 people, driven tens of thousands from their homes and caused billions of dollars in damage. On Tuesday, the governors of Illinois, Indiana, Iowa and Wisconsin asked President George W. Bush to allow the federal government to cover 90 percent of disaster-related costs incurred by state and local governments. The federal government usually covers 75 percent of such costs after the president declares a disaster. "Our states have suffered recent multiple disasters that have placed enormous stress on state and local governments," said Wisconsin Gov. Jim Doyle in a statement. "Reducing our share of the flooding assistance costs would greatly alleviate the social and economic impact on our families and communities that are suffering."
For days now, sandbaggers tried to fortify the levee to save the town of Foley, Missouri. But Sunday, June 22, 2008, the water proved to be just too strong.
Illinois got good news Tuesday when Bush declared 13 counties federal disaster areas. Gov. Rod Blagojevich has declared 24 counties along the Mississippi, in southeastern and northern Illinois, state disaster areas. Meanwhile, an earthen levee was all that was still protecting 100 houses, a city park, several businesses and 3,000 acres of agricultural land in east Winfield, one of the last towns in eastern Missouri where the upper Mississippi was expected to crest. Only National Guard soldiers and firefighters in life vests were allowed to stack sandbags, because volunteers and heavy equipment could sink. A single muskrat recently created a geyser of river water by digging into the berm.
For days, emergency management officials in Lincoln County have focused on the levee about 45 miles northwest of St. Louis. A storm with thunder and lightning Tuesday was only the latest impediment to the desperate attempts to shore up the Pin Oak levee. This storm is not a good thing," said Jeff Stamper, a structural engineer with the U.S. Army Corps of Engineers. "It pulled everyone off. You can work on a levee in the rain, but not in lightning."
The Mississippi was expected to finally crest at Winfield sometime late Wednesday, and to flow at its high-water mark - more than 11 feet above flood stage - for several more days. A disturbance as minor as a passing boat could lead to disaster.
A total of 35 levees have overtopped during the Midwest flooding, and seven of them had been federally designed and constructed, said Ed Hecker, chief of the office of homeland security for the U.S. Army Corps of Engineers. He said the nation's levee system wasn't designed to hold back such extraordinarily high flood waters, particularly in rural communities. "This system pretty much performed as designed," Hecker said.
The river continued to recede Tuesday from the Iowa line down through the lock and dam at Saverton, about 90 miles north of St. Louis. The river had dropped a foot Tuesday morning at Canton following a Sunday crest of 13 feet above flood stage. Pending further rains, the weather service said the river wouldn't begin to recede at St. Louis - where there is flooding, but none significant - until Thursday night. Forecasters said the last point on the river to finish cresting would be near Chester, Illinois, about 80 miles south of St. Louis, sometime Friday.

Severe Rains May Complicate Efforts To Keep Mississippi From Engulfing Communities
Darin Davis stands atop a sandbag wall as he surveys floodwater surrounding his house Thursday, June 26, 2008, in Louisiana, Mo. The waters have receded in some areas, but recent strong storms have renewed fears of additional and prolonged flooding.
Severe thunderstorms rattled northern Missouri early Thursday, threatening to add even more rain to the swollen Mississippi River and complicate efforts to keep the river from engulfing this community. Even before the latest storms, crews had long labored to strengthen the earthen levee at Winfield from dirt slides and spots where water soaks up through the sandy soil.
Lincoln County authorities on Wednesday deemed the area extremely hazardous and ordered boaters out of the water, saying even slight wakes lapping against the levee could cause a catastrophic failure. The 2½-mile-long levee about 45 miles northwest of St. Louis is all that's protecting 100 houses, a city park, several businesses and 3,000 acres of agricultural land in east Winfield. Forecasts showed the Mississippi will crest at Winfield at 37.5 feet on Friday, more than 11 feet above flood stage. But thunderstorms are forecast over the coming days upstream in Iowa, Minnesota and Illinois. At Clarksville, northwest of St. Louis, a weakened sandbag wall protecting the city's historic downtown was reinforced and was holding ahead of Friday's predicted crest of 36.9 feet. Downstream in Grafton, Ill., the crest forecast for Saturday evening was showing "a foot rise over what they've had so far," hydrologist and meteorologist Mark Fuchs said. A crest of 31 feet is expected, 13 feet above flood stage.
President Bush declared a major disaster area in 22 Missouri counties. The declaration makes federal funding available to state and local governments and certain private nonprofit groups to help deal with weather and water damage. U.S. Transportation Secretary Mary Peters promised $1 million in emergency relief for Iowa to help pay for urgent repairs to roads and bridges damaged by floods. The state was drying out again after storms erupted Wednesday afternoon and continued into Thursday morning. In central Iowa, 5 inches of rain were reported in Polk City, near Des Moines, while Ottumwa in the southeast received over 2 inches of rain in about 30 minutes.
Meteorologist Marc Russell of the National Weather Service said rivers in southeast Iowa are still in the major flood category and any more rain, just an inch, could cause flash flooding. Russell says the same holds true for the Cedar Rapids and Iowa City areas, which suffered major flooding.
Iowa officials said water quality tests show that floodwaters heading down the Mississippi River contain large amounts of bacteria, sediment and fertilizers like phosphorus and nitrogen. "When you have flooding of this scale, everything in the landscape is affected," said Iowa Department of Natural Resources spokesman Kevin Baskins. So far, tests have not turned up large amounts of industrial chemicals or other volatile materials in the water, he said. Crews are locating and removing all the floating propane tanks or other floating canisters they can find.

Het stadje Winfield in de Amerikaanse staat Missouri is van compleet overstroomd te worden gered nadat bewoners in allerijl een tweede dam met zandzakjes hadden geworpen nadat een andere van de vele dammen die het water van de Missippi in de bedding moeten houden was doorbroken, zo hebben Amerikaans media gemeld.
Vrijdag had de nationale meteorologische dienst gewaarschuwd voor een overstroming van de stad met zowat 900 inwoners bij een dijkbreuk. Meer dan twintig dijken begaven het langs de Mississippi, waardoor miljoenen liters water steden en landbouwgronden binnenstroomden, aldus de Genie van het Amerikaanse leger.
