How USGS Streamgages Work

This video explains how streamgages are used to measure the height and flow, or speed, of streams. By monitoring the height and flow of streams, the people who manage water infrastructure can have advanced noted of when the water is rising and how fast it’s coming. This helps to prepare for flooding, mudslides, and other hazardous impacts that a lot of fast-moving water can have. NOTE: The video was created for third graders. Some of the concepts have been simplified accordingly.
