Live Stream Gauges

Information on the amount of water flowing in streams and rivers is critical to the management of water resources, emergency response to flooding, fisheries management, and many other uses. This layer provides access to near real-time stream gauge readings compiled from a variety of agencies and organizations. Dataset Summary The Live Stream Gauges layer contains near real-time measurements of water depth from multiple reporting agencies recording at sensors across the world. This layer updates every hour. Flow forecasts are provided where available. These sensor feeds are owned and maintained by the GIS community via the [Community Maps Program]. For details on the coverage in this map and to find out how to contribute your organization's gauges, please email environment@esri.com. Contributors to the Live Stream Gauges Service: 1.
