The USGS provides practical, unbiased information about the Nation's rivers and streams that is crucial in mitigating hazards associated with floods. This site provides information about the USGS activities, data, and services provided during regional high-flow events, such as hurricanes or multi-state flooding events. The USGS response to these events is typically managed by the National Floods Specialist.
Heavy rainfall (locally as much at 8 inches in some locations) fell across parts of Missouri, Iowa, Illinois, Wisconsin, Michigan, and Indiana in mid-April, resulting in major flooding on several rivers. Late snow-melt in the northern midwest added to the flooding in late April and early May. The U.S. Geological Survey responded to the flooding with field crews from Water Science Centers across the region, ensuring gages continued to operate properly and making over 600 special streamflow measurements to verify accuracy of rating curves that enable USGS to translate stage into streamflow.
