KANSAS CITY, Mo. —The Missouri River breached two levees on Monday as river towns prepared for the worst of the flooding.
A South Dakota dam that has been releasing extra water for weeks will reach a peak today.
That means even more trouble for Hamburg, Iowa, and Big Lake, Mo., two towns near levees that were breached on Monday. Many residents in each town had already left.
Hamburg is protected by another levee, but the Army Corps of Engineers was unsure how well or how long it may hold up.
The 300-foot levee breach in Atchison County, Mo., near Hamburg, led to plans to close I-29 in the area. Iowa Department of Transportation officials expect the road to be flooded on Wednesday.
The interstate closing may extend into Missouri. It already has been closed near Council Bluffs, Iowa.
A secondary levee in Holt County, near Big Lake, may help hold off water in that area. Monday's breach occurred downstream of a recent repair.
The breaches won't lower the flood stage downstream toward Kansas City, but it probably will delay the peaks, corps officials said Monday. Officials had expected the highest water to take a bout four days from today's release in South Dakota to reach Kansas City.
The releases from Gavins Point Dam will hit 150,000 cubic feet of water per second today — more than double the previous release record in 1997 — because of heavy rains and snow melt in the north.
Outside the American Legion in Parkville there is a sign marking where the floodwaters of 1993 hit. More than 9 feet of water entered the hall that year.
"I don't think it will get in the building, but then again I didn't think it'd get in the building in '93," said Terry Brown, the building manager.
