Hoot Owl regulations are for emergency closures of watersheds in Montana. When water gets too warm for trout or other species, sport fishing is suspended. These closures will continue until the emergency has passed. A Hoot Owl closure can begin and end at any time the state biologists feel that the fish are in stress.
In recent years, Montana has experienced drought which means lower and warmer water flows. Low flows tend to congregate trout in shallow pools where they are more vulnerable. Catching and handling fish in warmer conditions increases stress, which can and often will kill the fish. This year’s snowmelt was sooner than usual and less flows are predicted in the future. Ironically, I am writing this article as snow is predicted for the first days of Summer. Montana has unpredictable weather.
The Hoot Owl closure is enforced from 2PM through Midnight. Some anglers still attack the fish in the cooler parts of the day but any fishing, at this time can be deadly to the trout, grayling, or other species. The areas with warmer waters become the destinations for massive crowds of tubers and swimmers escaping the summer heat.
Trout thrive in cold, clean water that is below 65 degrees. Even at this temperature, the trout become sluggish and threatened. Fungal infections and parasites also take their toll.
Currently, there are Hoot Owl closures in place. This is earlier than usual and projects to include many other waters throughout the state sooner than in past years. The upper Madison River, in Yellowstone Park, is now closed. This river flows into Hegben Lake, then Quake Lake further downstream. The dams allow for cooler waters to be released, which helps to protect the upper Madison River fisheries. The Lower Madison River, below Ennis, will probably be next to close due to warming and lower waters.
Anglers need to check the FWP website for current and potential closures. Planning a trip could be affected if your destination is under Hoot Owl restrictions. Watersheds along the Beaverhead, Ruby, Bitterroot, and other popular rivers are already showing signs of warming and drought.
Hoot Owl restrictions often flow into late August and September, before being lifted.
