Hydrologic Monitoring in Yellowstone National Park
River-Discharge and Chloride-Concentration Data
Analysis of long-term river discharge and chloride concentrations in
major rivers in Yellowstone provide a quantitative estimate of the
total heat discharge from the Yellowstone volcanic system and can also
be examined for temporal trends associated with magmatic and tectonic
activity. Learn more.
Hydrologic Data (from the U.S. Geological Survey)
- Stream discharge and temperature at Tantalus Creek, Norris Geyser Basin
- Provisional real-time stream-flow data from the USGS of the major rivers draining Yellowstone National Park.
