Blue River Near Green Mountain Reservoir Fishing Report – November 2024
The Blue River below Green Mountain Reservoir is a peaceful, productive tailwater fishery, perfect for late fall fishing. With flows consistent around 75-100 CFS, this section of the Blue River offers steady, clear water and cooler temperatures that keep the trout active during midday hours. The trout are settling into winter patterns, which means a mix of subtle nymph presentations and occasional surface action during midge and BWO hatches.
For anglers seeking solitude and larger fish, this area is ideal. The deeper pools and slower runs make it a rewarding experience for nymph and streamer enthusiasts, especially when targeting rainbows and browns as they bulk up for the colder months. Light presentations and stealthy approaches will pay off in this beautiful, quiet stretch of the river.

Tips Fly Fishing on the Blue River Below Green Mountain Reservoir
Seasonal Tip
Focus on midday fishing for the most active trout, as the colder mornings often keep them subdued until temperatures rise.
Dry Fly
Small BWOs can be productive during mid-morning to early afternoon, especially in slower sections of the river. A well-placed Blue Wing Olive can tempt even the pickiest trout to the surface.
Nymphing
A two-fly nymph rig with a Pheasant Tail and Zebra Midge is your go-to here. Work the seams, riffles, and tails of pools, adjusting weight for the river’s slower flows.
Streamer Fishing
For targeting larger trout, use an Olive Sculpzilla or similar streamer pattern. Keep retrieves slow, focusing on deeper sections and areas with structure.
