Lower Madison Fishing Report

Updated 02/05/2026

Current Flow: ~ 1,360 CFS below Ennis Dam

The Lower Madison River is fishing well heading into this weekend, with the river mostly open and accessible despite some scattered floating ice in calmer backwaters. Conditions have been relatively straightforward, with late morning through afternoon producing the most consistent action, especially when winds settle and surface insects are active. Nymphing remains the most productive approach right now, with trout holding deep and keying in on weighted rigs with lightning bugs, zebra midges, and small mayfly nymphs getting frequent eats. Streamer fishing is also beginning to pick up, particularly in softer water and slower runs where larger crayfish and sculpin patterns can draw aggressive takes, while dry fly chances on midges are showing up during warm spells and calmer periods.

With warmer weather expected this weekend (highs into the low 50s), look for mid-winter midge activity to continue increasing and dry flies to become a more viable option around midday when the sun’s on the water and trout become more surface-oriented. Choosing calmer windows and focusing on deeper seams for nymphing will keep anglers busy, and don’t hesitate to sneak in some streamer work during cloudier or lower-light periods to trigger aggressive fish. Overall, the Lower Madison should offer solid winter fishing — especially for anglers prepared to read water, keep flies deep when needed, and adjust tactics as the warm afternoon conditions build.
