Lake Granby fishing report
Updated November 7, 2026.
Lake trout fishing is excellent right now, and surface water is in the low 50s. The lake is only about half full after a dry year.
The Stillwater boat ramp is closed for low water, and Sunset Point ramp closes November 29. From shore, fish the dams and creek inlets with an egg-sucking leech or streamers for rainbows and browns.
Low water may bring ice earlier than usual this year.
