  • Comments:
    Kids back in school means much less traffic on the river! Warm weather, great fishing, vibrant colored leaves and healthy trout are a few words which represent the Green River in September. September fishes very well with grasshoppers, flying ants, and beetles. The trout key into brown flies, and begin their pre-spawn rituals.
