Low stream flows and high temperatures are triggering fishing closures on some Yellowstone National Park rivers.
The following waterways will be closed to all fishing, starting Wednesday:
• Gibbon River below Gibbon Falls
• Firehole River below Keppler Cascades
• Madison River
"Hot air temperatures, limited rainfall, runoff from thermal features and below average stream flows have all resulted in high water temperatures in these rivers," according to the release from a park. "Water temperatures in the Gibbon River have been above 73 degrees most of the past two weeks, with water temperatures in the Firehole River above 78 degrees temperature."
Water temperatures this warm can be stressful and even fatal for trout.
Park staff will continue to monitor water temperatures and stream flows in these and other rivers and streams throughout the park.
