As of September 23, 2024, the Bighorn River in Montana is offering some exceptional fishing opportunities, despite the approaching winter season.

### Current Weather Conditions
The weather in the Fort Smith area is mild, with temperatures expected to be in the mid-50s to low 60s Fahrenheit. Wind speeds are moderate, around 10-15 mph, and there is a slight chance of light precipitation. These conditions make for a pleasant day on the river.

### Water Conditions
The Bighorn River is currently flowing at about 2,500 cubic feet per second (CFS), which is relatively stable and favorable for fishing. The water temperature is around 54 degrees Fahrenheit, and the clarity is good, although some drifting algae can be an issue, especially below the 3-Mile Access.

### Best Fishing Spots
For today, the best spots to fish include the stretches from Afterbay to 3-Mile Island and the Bighorn Access. Wading and floating both offer good opportunities, but be cautious of the algae when floating.

### Bait and Tackle Recommendations
Given the time of year, subsurface patterns are highly recommended. Worms and crustaceans are top choices, with flies like the Gummi or Squiggly Worm (Size #10), Firebead Sparkle Worm (Size #12), and Bighorn Scuds (Size #14-18) being particularly effective. For dropper flies, consider the Firebead Soft Hackle Ray Charles (Size #14-16) or FoJay's UV Eddie Vedder (Size #16-18).

Nymphing is the most consistent method, with PMD and sowbug imitations working well. Flies like the Crack Back PMD, Black Perdigon, and Ray Charles (grey or tan) are excellent choices. If you're looking to try dry fly fishing, PMD spinners, Pale Olive Baetis, and Tricos in the morning, along with black caddis in the afternoon and evening, can be productive.

### Fish Activity
Fish are currently feeding on subsurface patterns, and nymphing about 5 feet under an indicator is a good strategy. They are also eating PMD spinners and black caddis on the surface during calm and cloudy conditions. Streamer fishing can be hit or miss, but using a sinking tip line with medium-length strips can yield results.

### Local Events and Regulations
There are no major local events or fishing tournaments scheduled for today. However, it's important to note that rainbow trout are not currently spawning, but it's always a good idea to avoid any spawning redds you might encounter. Catch limits and regulations remain standard, so ensure you have the necessary licenses and follow local guidelines.

### Tips from Local Anglers
Local anglers and guides recommend focusing on the afternoon for better fishing conditions, as the morning can be tough. A good first drift is imperative, so make sure your presentation is spot on. For streamer fishing, cloudy days are generally better, and using a sinking tip line can improve your chances.

### Best Times for Fishing
The best times for fishing today are likely to be in the late morning to early afternoon, when the fish tend to become more active. If you're targeting surface action, the morning and late afternoon are your best bets for catching fish on PMD spinners and black caddis.

Enjoy your day on the Bighorn River, and remember to check with local fly shops like the Bighorn Angler and the Bighorn Trout Shop for the latest updates and advice.
