Streamflow Measuring Tools

The USGS equipment pictured here measures streamflow when submerged in river water during high flow events. In the background, Ben Glass of the USGS Colorado Water Science Center collects flood data on the Big Thompson River in Loveland, Colo. The river is one of many that flooded during a significant September 2013 rain event along Colorado's Front Range, damaging or destroying several USGS streamgages.
