YELLOWSTONE NATIONAL PARK — All temperature-related fishing restrictions in Yellowstone National Park (YNP) have been lifted.
According to a press release sent Monday, Sept. 8, fishing is now open in all rivers and streams that were partially closed due to warm water temperatures and low flows. Per YNP’s statement, the partial closures were necessary to protect the park’s native and wild trout fisheries when water temperatures exceeded 68°F.
Park staff monitored the rivers and streams throughout the closure and have determined the restrictions can be lifted due to cooling temperatures, recent precipitation and an extended forecast of cooler weather and rain.
The lifted restrictions relate to the following areas:
- The Madison River and all associated tributaries
- The Firehole River and all associated tributaries
- The Gibbon River and all associated tributaries downstream of Norris Campground
