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.
USGS crews from Montana to Missouri watched closely as a higher-than-average snowmelt runoff combined with heavy spring rains advanced down the Missouri River system. Large reservoirs managed by the US Army Corps of Engineers (USACE) are carefully managed with the help of data from the USGS streamgaging network to control flood levels.
