Twin Bridges, MT fishing report
Twin Bridges sits at the confluence of three distinct tailwater and freestone personalities, and brown trout dominate the lower Beaverhead's slow, undercut banks while rainbow trout run stronger in the faster, more oxygenated Big Hole riffles. Spring runoff pushes fish tight to softer water near the banks. By midsummer, heat drops trout into deeper pools and feeding shifts to early morning and evening. Fall triggers aggressive pre-spawn behavior in browns, making October a prime window before cold shuts things down.
Watch water temperature closely — trout go off the feed above 68 degrees, so fish early or target spring-fed side channels when mainstem temps climb. Nymphing with PMD, caddis, and crane fly patterns covers most of the season. In faster Big Hole pocket water, dead-drifting a hopper-dropper along current seams is deadly from July onward. On the Beaverhead, tight presentations against deeply cut banks using streamers on a down-and-across swing draw strikes from large browns holding in slow, dark water.
