September marks the beginning of fall on Montana's lower Madison River below Ennis Lake. Cool, fall weather revitalizes the river, and Brown Trout start to show their autumn colors.
Recreational crowds disappear and leave the river to Montana anglers for the remainder of the season.
The blue-winged olive and Pseudocleon mayfly activity increases as the weather cools. The occasional rising fish can be found in the slick water next to the banks and below structures like weed beds and boulders.
Rainbow and Brown Trout actively feed on Crayfish, Sculpins, and the small nymphs of hatching insects in the buckets and fast runs between the Madison Dam and Black’s Ford fishing access site.
Set the hook fast on any pause or hesitation of the strike indicator or dry fly with a dropper. Nymphing with split shot and streamers or Crayfish patterns are standard lower Madison fishing setups this time of the year.
Dry fly anglers will find the odd rising fish in flat water on overcast days during BWO hatches.
With lower flows and clear water at this point in the season, trout can become a little pickier. Try to be as stealthy as possible when approaching the water you want to fish by using fluorocarbon tippet and longer leaders. We like Rio's FluoroFlex Strong in 4x-6x on a 9ft leader for nymphing.
