The United States Geological Survey (USGS) operates a network of real-time streamgages that continually record stage and streamflow every 15 to 60 minutes. Streamflow information from streamgages have a wide variety of uses, including flood prediction, water management and allocation, engineering design, scientific research, and recreation. Streamgage data are available online through the National Water Information System (NWIS) and USGS WaterWatch Web sites.
