What Are Hoot Owl Restrictions?

Hoot Owl restrictions are fishing regulations implemented in Montana to protect trout during periods of high water temperatures and low flows. These rules typically limit fishing to the cooler hours between midnight and 2 p.m., coinciding with the nocturnal activity of hoot owls.

Montana Fish, Wildlife and Parks (FWP) enacts these restrictions when water temperatures reach 68 to 73 degrees Fahrenheit for consecutive days. They primarily affect popular trout fishing rivers like the Gallatin, Clark Fork, and Big Hole.

In extreme cases, full closures may be implemented. On August 3, 2024, the Jefferson River and parts of the Big Hole River were completely closed to fishing due to dangerously low water flows.

Anglers are advised to check the FWP website for current restrictions and follow best practices:

• Use barbless hooks
• Keep fish in water when possible
• Stop fishing if water feels too warm

As climate change intensifies, these restrictions may become more common. Local guides emphasize the importance of these measures in preserving fisheries for future generations, noting that early morning fishing under Hoot Owl rules can still provide excellent angling opportunities.

By respecting these regulations, anglers play a crucial role in protecting Montana's cherished trout populations during challenging environmental conditions.
