Big Horn Montana Fishing Report - May 18, 2025

Hello folks, this is Artificial Lure with your Big Horn Montana fishing report for May 18, 2025. We've got perfect spring fishing conditions today with temperatures expected to reach the mid-60s. It's a beautiful morning with light winds forecast to pick up slightly in the afternoon. Sunrise came at about 5:30 am and sunset will be around 8:35 pm today, giving you plenty of daylight hours on the water. The Bighorn River is running clear with good flows for both wade and float fishing. Water temperatures are hovering in the upper 40s, which has the trout actively feeding. No need to worry about tides out here in Montana—our fish operate on different schedules! The resident trout population is looking mighty fine this season. Anglers have been consistently landing rainbows and browns in the 16 to 20 inch range, with some lucky folks connecting with bruisers pushing 22 inches. The 18+ inch class has been particularly active over the past couple weeks. Nymphing remains your best bet for consistent action. Those Tailwater Sowbugs in sizes 14 and 16 are still producing well, along with #18 Wonder Nymphs and Flashback Quill Nymphs. For your top fly, try a Two-Tone Scud or an Orange Scud. Midges are also working nicely, especially the #18 Tung Teaser during morning hours. If you're patient, some dry fly action is available later in the day. Pack some #20 Sipper Midges, CDC Midges, and Baetis patterns like the Cripple Thor for when you spot risers. Streamer fishing has been improving for those targeting bigger fish. Sparkle Minnows, Skiddish Smolts, and Geisha Girls have been turning heads. Remember to fish them slow and deep in slower water for best results. For hot spots, the section below the dam has been consistent, but don't overlook the water about 3-4 miles downstream where pressure is lighter. Just keep an eye on Soap Creek about 10 miles down—spring rains can make things murky there when it runs. The river has been fairly busy but not overwhelming. If you're looking for more solitude, try hitting the water early or fishing into the evening hours when most folks have called it a day. Stop by the shop if you need anything—we're open daily from 7am to 6pm. Tight lines, everyone! This content was created in partnership and with the help of Artificial Intelligence AI.
