USGS water data expert Garret Welsh measures water flow in the pouring rain at the Straight River near Faribault, Minnesota. This measurement recorded the 6th highest flow in the station's 59-year history, highlighting the severity of current flood conditions. Such data is crucial for emergency managers and forecasters to protect communities at risk.
