Conditions & the best window
The prime bite is dawn and the last hour of light, strongest around the new and full moon. Today's sky on the Madison River looks overcast (about 90% cloud) — and an overcast day can actually keep fish looking up. Watch the flow as much as the sky: a sharp change in discharge, up or down, can turn the fish off for a day.
The "$3 Bridge" to Lyons stretch is classic wade water; below Quake Lake the river braids and pockets. When flows climb in spring runoff, drop down to the dam-buffered upper reaches or fish a guided float that reads the clearer seams.
