It's still wet!

During the heavy rains earlier this year, the Meramec River flooded significantly. However, since most of the rain didn't fall within the Mississippi River catchment, the levels in The Mississippi didn't really rise that much. However, the latest batch of heavy rains combined with the already saturated ground from the seemingly endless rain this year lead to significant flooding in the Midwest. Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, & Wisconsin were the states most affected by the flooding. There were a number of towns & villages north of St Louis that needed their levees raised to prevent floodwater from inundating residential & commercial areas. This was mostly done with sandbags filled & placed by numerous volunteers & the National Guard. The levees seemed to be holding but with the river level practically at the top of the defences for an extended period of time (mainly due to the huge volume of water draining to the Upper Mississippi Catchment) a number of levees eventually breached. This helped to slightly reduce the flooding in St Louis, but the river still crested 10 feet + above flood level which meant that the riverfront was completely submerged & flood waters encroached upon the Arch grounds. In total, thirteen people died in the flood & damage estimates were in the tens of billions of dollars.
