Madison River Fishing Report - 2025-11-10

River Description

The Madison River in Ennis, Madison County, Montana, flows through a classic freestone valley with riffles, runs, and deep pools ideal for trout fishing. Current conditions show stable but below-average flows (904-1160 cfs across gages, -1% to -34% vs. historical averages) and cold water temperatures (37.9-40.5°F, well below the 53-56°F seasonal norms), signaling a late-fall slowdown in river activity. This creates a technical nymphing river with limited surface action, as trout metabolism is low in the chilly water. Fishing potential is fair for opportunistic anglers targeting brown trout in deeper slots, influenced by mostly cloudy skies and southerly winds that could stir sediment but also bring subtle hatches. Lunar conditions feature a waning gibbous moon (66% illumination), with last quarter approaching on Nov. 12, potentially reducing overnight feeding but not severely impacting daytime efforts. Overall, the river's character leans toward subsurface presentations amid cooling patterns.

3-Day Forecast

Limited detailed forecast data is available beyond today, but trends suggest stabilizing fall weather with minimal precipitation. Today (Monday, Nov. 10): Mostly cloudy with highs near 61°F and lows around 34°F, south winds at 15-20 mph, and 53% humidity—conditions that may increase water clarity for sighted nymphing but gusts could challenge dry fly drifts. Tuesday and Wednesday: Expect similar patterns with partly cloudy skies, highs in the low 60s°F, and lighter winds (10-15 mph), as dew points rise slightly from 23°F. These trends favor improved visibility and modest hatch activity if temperatures hold, though persistent cloud cover might suppress aggressive surface rises; no major fronts or rain are indicated, keeping flows steady.

Fishing Outlook

Fair overall for fly fishing success, as cold water temperatures (37.9-40.5°F) slow trout activity, limiting explosive hatches but creating windows for selective feeding in riffles and seams. Stable flows (900-1100 cfs) provide safe wading in most sections, allowing precise nymph drifts without overcrowding; however, below-average volumes concentrate fish in deeper runs. Weather warming from yesterday's 20°F low to 61°F highs boosts minor insect emergence, potentially aiding midges and blue-winged olives, while the waning moon phase subtly dampens crepuscular bites. Success hinges on subsurface tactics, with brown trout staging for spawn—target them over rainbows, which may be less active in the chill.

Recommendations

• Flies & Techniques: Focus on nymphing with small patterns like #14-18 Pheasant Tail or Hare's Ear nymphs in olive or natural tones, dead-drifted under indicators in 3-6 ft depths to mimic midges and Baetis; add streamer fishing using #4-6 Woolly Buggers in black or olive, swung slowly through tailouts to provoke territorial browns. For any surface windows, try #18-22 Parachute Adams during cloudy afternoons if midges show.
• Best Times & Tips: Optimal windows are 10 AM-3 PM when solar warming peaks, avoiding early mornings with frost risks; late evenings could yield streamer action near dusk. Wading is moderate with current gage heights (2-4 ft), but stick to known shallows—cold water increases hypothermia risk, so layer with wool and neoprene socks. Watch for wind gusts up to 20 mph affecting casts; fish undercut banks for holding trout.
• Gear Notes: 5-6 wt rods for versatility in nymphing and streamers; use 9 ft leaders with 4-5X tippet to handle subtle takes in clear, cold flows. Pack floatant and split shot for depth control.
