The Lower Clark Fork River is holding steady with water temps around 45 degrees, as of February 10th, keeping things squarely in late-winter mode. According to the latest report via Orvis, conditions are fishable, but it’s still a subsurface game for now.
As Tim Linehan notes, this is the time of year to stick with nymphing and streamers to move fish. Expect partly sunny skies and daytime highs in the 30s to low 40s through most of the week, with a rain-snow mix possible as the weekend rolls in.
Focus on deeper runs and slower holding water, and plan on keeping your flies down—nymphs and streamers remain the go-to approach for consistent action.
