Bighorn River Fishing Report: Trout Aplenty, Nymphs and Streamers Shine on Opening Day

Fishing on the Bighorn River today, April 14, 2025, is shaping up to be excellent, with the river in great condition and fish actively feeding. The stream flow is steady at approximately 2,240 cfs, and the water clarity is clear, offering ideal conditions for anglers. Water temperatures are hovering around 48°F, which favors both nymphing and streamer fishing. The weather today in the Big Horn, Montana area is cool and crisp with some cloud cover, a promising sign for fish activity. Sunrise was at 6:22 AM, and sunset will be at 7:57 PM, providing plenty of daylight for a full day on the water. Recent catches in the Bighorn have been impressive. Anglers are reporting good numbers of brown and rainbow trout, with an estimated 3,500 trout per mile in this fertile tailwater. The size of these fish has been solid, with some browns and rainbows reaching 20 inches or more. Nymphing has been the most productive technique recently, with common patterns like sowbugs, scuds, and midges performing consistently well. Streamers such as Sparkle Minnows and Rusty Trombones are also drawing strikes from larger trout, especially during the warmest part of the day when fish are more likely to chase. For bait and lures, anglers should focus on the local hatches. Blue Winged Olives (BWOs) and midges dominate this time of year. High-performing flies include Cotton Candy, Red Bead Carpet Bugs, Tailwater Sowbugs, and Black Zebra Midges. For streamer enthusiasts, darker patterns like Black Micro Mayflies and Olive Jiggy Perdigons have been yielding success. Spin anglers might find luck with Rapalas in rainbow or silver colors, as well as Panther Martin spinners in black and gold. Two recommended hotspots for today's fishing are: 1. The Three Mile Access area, where nymphing in riffles and deep runs has been particularly effective. 2. The Afterbay Dam section, where both wading and drifting offer opportunities to hook into large trout. This area is ideal for working streamers along deeper slots and seams. With light crowds and actively feeding fish, today is a prime day to be on the Bighorn River. Bring your mid-weight rods and fresh tippets, and be prepared to adjust techniques as conditions shift throughout the day. Keep your presentations precise, and you'll leave with stories to tell!
