Lower Madison River Fishing Report: Pre-Caddis Nymphing & Stable Flows

Written By David Kern

Fishing on the Lower Madison has been fantastic recently, with a noticeably high number of tagged fish moving through the system right now. As with any spring fishing in Montana, timing your day is the biggest variable. If you can navigate between the wind gusts and wait for that afternoon warmth to hit the river, the effort is absolutely worth your time.

Water Conditions The water has picked up a slight olive/brown tint, but the dam has kept flows fairly stable all week. That consistency in volume is playing to our advantage right now, keeping the fish holding in predictable seams and feeding confidently despite the color.

What They’re Eating: Dialed-In Subsurface Tactics With the slightly off-color water, you need to rely on high-visibility attractors paired with slim-profile droppers that cut through the water column quickly.

  • The Attractors: Fish are aggressively eating egg patterns. Pegged eggs, specifically Montana Trout Beads in orange, are highly effective right now. Red and pink wire worms are also pulling their weight as lead flies, giving the fish an easy, high-protein target in the tinted water.

  • The Droppers: Trail your eggs or worms with smaller, subtle olive nymphs. France Flies and olive Perdigons (sizes 16-18) are getting the most consistent action.

Hatch Forecast: An Early Mother's Day We are starting to see a few caddis flying around, though we aren't into the thick of the full Mother's Day hatch just yet. However, based on the current weather patterns and water temps, that hatch is going to happen very early this year. Start organizing your dry fly boxes now.
