The fishing has been moderate to fair lately, with nymphs and streamers being the most effective. Although some aquatic vegetation is drifting downstream, the conditions are becoming more favorable beyond Bighorn access and mallards.
While it is possible to catch fish during the winter season, activity tends to diminish as temperatures drop. However, in contrast to many other trout waters in Montana, the Bighorn River remains free of ice throughout winter due to dam regulations.
The optimal time for winter fishing on the Bighorn River is typically from late afternoon until evening.
