What is a streamgage?

Information on the flow of rivers and streams is a vital national asset that safeguuards lives, protects property, and ensures adequate water supplies for the future. The USGS operates a network of more than 9,000 streamgages nationwide with more than 150 in Utah, but how does a streamgage work? Dee Lurry of the Texas Water Science Center answers that question.
