As of October 5, 2024, the Big Horn River in Montana is offering some excellent fishing conditions, especially with the fall season in full swing. Here’s what you need to know for a successful day on the water.

The river is flowing at about 2,500 cubic feet per second, which is near normal levels for this time of year. The water temperature is around 59 degrees, and the clarity is clear, making it perfect for spotting trout.

Weather conditions are typical of the fall season, with crisp mornings and pleasant days. Expect partly cloudy skies with cooler temperatures, which can enhance fish activity. Sunrise is at around 7:30 AM, and sunset will be around 6:30 PM, giving you a full day to enjoy the river.

Fish activity has been good, particularly in the afternoons. Anglers have been catching a mix of rainbow and brown trout, with the average size being around 16 inches. Nymph fishing, although a bit challenging in the mornings, improves significantly as the day progresses.

For nymphs, SJ Worms, sowbugs, Perdigons, and tan caddis pupa have been the top producers. If you're looking to fish dry flies, tricos, although spotty, and tan caddis are worth trying. Streamer fishing has been mediocre, but patterns like the Articulated Goldy, Dirty Hippie, and White Zonker are still worth a shot.

Aquatic grass is a bit of an issue in some areas, so look for clean lanes to cast your line. The section of the river from the dam to the Bighorn Access, a distance of about thirteen miles, contains the highest population of trout and is highly recommended.

Another hot spot is the area between Log Gulch and Split Rock, where the river splits into channels, flats, and pools, providing a diverse habitat for trout.

Overall, the Big Horn River is in great shape for fall fishing, with plenty of opportunities to catch good numbers of trout. Enjoy your day on the water
