Lower Madison River Fishing Report

Lower Madison River Fishing Report

12/31/25

Start the New Year off right by getting out on the water and catching some fish! The unusually mild start we have had to the winter has given us some great angling opportunities.

The Lower Madison River is an incredible angling option all winter long. With it being a tailwater we see slightly warmer water temps here than on most rivers and the fish stay pretty active.

There's not a real reason to try and hit the water right at the crack of dawn, most of the action is happening during daylight hours between 10am and 3pm. When the sun has been on the water for a little over an hour you can expect to see some emergence from midges as long as there isn't too much wind.

Try to rotate through worms, midges, rubber legs, and leeches. Focus on the deepest water you can find and enjoy the day!

Dries: Stick Midge Adult #20, Griffith Gnat #18-20, Doc's HV Psuedo #20

Nymphs: Nyman's Shop Vac #16-18, Perdigons (Black, Pearl, Green, Purple) #18-20, Spanish Bullet Perdigon #16-18, Rubber Legs (Black, Coffee/Black, Olive) #10-12,

Streamers: Sex Dungeons, Barely Legals, Copper Zonkers, Sheila's Sculpin, Silk Kitty, Mini Kill Whitey, Li'l Kims have been productive.  Play with color and profile every day. Skinny vs. big heads, dark vs. light, etc.
