Stream Gauge
Stream Gauge

Stream gauges are ground-based sensors that provide in situ measurements of the stage or height of rivers and streams. The stream flow or discharge of the river can be derived from the stage measurements. Stream gauges can provide continuous measurements and are useful for monitoring flooding potential and water supply. The United States Geological Survey (USGS) maintains and operates a network of over 10,000 stream gauges across the United States to aid with flood forecasting and water management.
