HELENA – Due to recent rains and cooler temperatures, fishing restrictions will be adjusted on the entire Jefferson River and a section of the Madison River, effective immediately. Water temperatures have met the criteria to change fishing restrictions and FWP expects the temperatures to remain cool.  

Jefferson River: The full fishing closure on the Jefferson River, from the confluence of the Big Hole and Beaverhead rivers to the Missouri River, has been lifted. 

Madison River: Hoot-owl restrictions are now in effect on the entire Madison River upstream of Hebgen Reservoir including the sections of the Madison River that are surrounded by Yellowstone National Park – from the park boundary through the three short sections near Baker’s Hole campground. The hoot-owl replaces the full fishing restriction that had been in effect since July 17 and aligns with the existing hoot-owl restriction in Yellowstone National Park. 

The restrictions had been in effect for the rivers due to warm water temperatures. Hoot-owl restrictions prohibit fishing from 2 p.m. to midnight each day. They are designed to protect fish that become more susceptible to disease and mortality when low flows and high water temperatures combine with other stressors, including catch-and-release fishing.  Anglers can reduce stress on fish at all times of the year by getting fish to the net or in hand quickly, keeping them in the water, and reviving them prior to releasing them back into the river.  

Along with monitoring stream temperatures, FWP also monitors stream flows, and in some streams, holds instream flow water rights. FWP’s water program can issue a call on junior water users, when appropriate, to contribute to stream flows through the late summer and early fall.
