Yellowstone Fishing Closures Highlight Conservation Efforts
Yellowstone National Park has implemented temporary fishing restrictions on key waterways to safeguard trout populations amid high temperatures, according to a news release from Yellowstone National Park. The closures, effective Thursday, target rivers and streams where water temperatures have exceeded 68°F (20°C), a threshold deemed lethal for native trout species.
Which Rivers Face Restrictions?
The following waterways will be closed to fishing daily from 2 p.m. to sunrise:
- 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
These closures aim to reduce stress on trout, which are particularly vulnerable to high water temperatures and low flow rates. Park officials note that temperatures drop at night, allowing limited fishing opportunities during cooler hours.
Open Areas and Angler Guidelines
Fishing remains permitted in Yellowstone Lake and other lakes under the 2026 Fishing Regulations booklet, with hours from sunrise to sunset. Anglers targeting non-listed rivers and streams should still adhere to general guidelines, including quick catch-and-release practices.
“Do not play hooked trout to exhaustion. Gently handle fish in the water as much as possible and let them recover before release,” the park advises.
Why High Temperatures Threaten Trout
The park reports that Yellowstone’s recent heatwave, with air temperatures near 90°F (32°C), has exacerbated conditions.
Monitoring and Future Adjustments
Park staff will continuously monitor water temperatures. Closures may be extended or modified based on these metrics. The park notes that closures will remain in effect until conditions improve.
“Your cooperation will protect the park’s fisheries,” the release states.
