This USGS website provides real-time and historical stream-flow data from the major rivers draining Yellowstone National Park. Data from thirteen gaging stations within and around the Park can be selected from a list or map. Data and graphs are available for gage height, stream discharge, and in some cases, temperature. Water quality sampling results and a link to EPA information on the watershed are also available for all stations.
