Higher than average snowfall through the winter created a wet snowpack across much of Iowa which was still present into early March. A large storm system impacted the region through the middle of March which brought heavy rain and warm temperatures to the state. This system allowed much of the snowpack to melt across the state within a few days to a week. This heavy rain fell on frozen ground allowing nearly all of the rainfall and snowmelt to runoff into the river systems. This led to flooding
