The Mississippi River is topping out at some problematic spots, but there is growing concern that spring floods are far from over. The river was at or near crest at several places Sunday between the Quad Cities and near St. Louis. The good news was that most businesses and homes were high and dry, though hundreds of acres of farmland were under water, bridges were closed at Quincy and Louisiana, Mo., and countless roads were shutdown. But river towns aren't yet in the clear: An inch or more of rain is in the forecast as well as continuing accumulation of snow to the north, especially in Minnesota and the Dakotas. Flood watchers along both the Missouri and Mississippi rivers know that once that snow - record levels in some cases - melts, a lot of it ends up in the big rivers. Rain last week started the whole mess, causing the Mississippi and many other rivers to surge in Missouri, Illinois, Iowa, Wisconsin, Michigan and Indiana. Adding to concern is the forecast. National Weather Service meteorologist Julie Phillipson said an inch of rain is likely in many places Monday night into Tuesday, some places could receive more than that. In La Grange, Mo., sandbags were holding back the murky Mississippi River water at City Hall, a bank and a handful of threatened homes, and the water was dropping. This flood was little more than an inconvenience, Lewis County emergency management director David Keith said. "What we're worried about now is all that snow melt in North and South Dakota and Minnesota," Keith said, referencing the state's mounds of April snow. Forecasters said up to 6 inches of new snow were possible in the Black Hills area of South Dakota through Monday morning. But AccuWeather meteorologist Alan Reppert said it may stay cold long enough to the north to make for a gradual melt. Sandbagging was beginning this week in Fargo and Cass County to prepare for forecast record amounts of high water along the Red River and its tributaries. By Sunday, sandbagging had all but stopped in Clarksville, Mo., evidence of the confidence in the makeshift sandbag levee hurriedly erected to protect downtown. The river Sunday was about 10 feet above flood stage and expected to rise another foot before cresting Monday.
