These cold nights have been locking up most of the Gallatin- more open water in the canyon towards Big Sky. A warm-up is expected first week of February where we will see more ice breaking up.

Fish have officially moved into their winter grounds. They will be stacked up in deep slow runs. If you find one fish, you will probably find a load of them.

Fish conserve energy this time of year but will feed on smaller aquatic bugs such as zebra midge, rainbow warrior, small rubber legs, lite brite perdigon along with worms and the last of the egg bite. If you're not picking fish up, you're probably not deep enough. Adjust your depth before switching fly's and don't be afraid to use a little split shot.

Winter tips:

  • Fish the warmest parts of the day
  • Use a wading staff for stability and to check ice thickness
  • Winter fishing can be tough on the body, dress in layers and stay warm
  • Keep your rod and reel out of the water to eliminate your guides and reel from freezing
  • Use a net to land fish, having cold wet hands is the easiest way to end a day of fishing
  • Minimize fish handling and land fish quickly.
