HELENA, Mont. -- The devastating flooding that occurred along the Yellowstone River this week constitutes a 1 in 500-year event, according to a US Geological Survey news release.
"At two streamgages, Yellowstone River at Corwin Springs and Yellowstone River at Livingston, the peak streamflow was higher than the 0.2% flood ," said USGS hydrologist Katherine Chase in the release. The USGS frequencies are calculated from historical data for the Yellowstone River's locations. As CNN has reported this week, scientists have shown climate change is impacting the frequency at which extreme weather events occur, and the trend is expected to continue as the planet continues to warm.
"We have made tremendous progress in a very short amount of time but have a long way to go," Superintendent Cam Sholly said in the release."All emergency and life safety objectives within the park have been accomplished or stabilized within the first 96 hours of the flood event, without major injury or death."
Backcountry areas accessible from roads open to the public will be available for day use only, according to the release. Overnight use from trailheads in the south will open on July 1. "The interim plan, referred to as the Alternating License Plate System , was suggested as a solution by gateway communities during major public engagement with the park this past week," the release read.
