Fishing Closures Announced in Yellowstone National Park
Park officials said water temperatures topped 68 degrees and low flows can be deadly for trout, prompting daily closures until sunrise.
- Effective Thursday, July 9, 2026, Yellowstone National Park restricted fishing on the Madison River, Firehole River, and Gibbon River daily from 2 p.m. to sunrise due to water temperatures exceeding 68 degrees and low river flows.
- Warm water conditions can be lethal to trout, prompting the National Park Service to impose these closures. Although the park opened these fisheries earlier than unusual this year, recent heat forced the restrictions.
- Anglers may continue fishing affected areas in the morning when water cools overnight. Yellowstone Lake and other non-restricted waters remain open from sunrise to sunset, and staff ask anglers to land fish quickly and handle them gently.
- Park staff will continue monitoring water temperatures to determine whether closures should be lifted or expanded. Forecasters expect air temperatures to reach near 90 degrees in coming days, potentially intensifying conditions.
- These measures aim to protect the park's native and wild trout fisheries during vulnerable conditions. Public cooperation is essential to safeguard ecosystems until water temperatures return to safer levels.
