Yellowstone River level and discharge during June 9–16, 2022, at Corwin Springs streamgage north of Yellowstone National Park
Yellowstone River level (left) and discharge (right) during June 9–16, 2022, measured at the Corwin Springs streamgage just north of Yellowstone National Park (https://waterdata.usgs.gov/mt/nwis/uv/?site_no=06191500&PARAmeter_cd=00065,00060,00010). The previous record flooding event at the site was in 1918, when the level was at 11.5 feet and discharge was measured at about 32,000 cubic feet per second. The flooding of June 13, 2022, shattered that record, with a level of almost 14 feet and a preliminary discharge of about 50,000 cubic feet per second. Data from this site extend back to 1892 and provide an exceptional example of the value of long-term monitoring for tracking, forecasting, and warning of flood events.
