Steelhead fishing on the Trinity River in the winter can also be productive. Although the weather may not be as accommodating as the fall, fishing can more than make up for the colder temps, as we typically see the biggest fish of the year during the cold, wet winter months. These are the conditions that separate the diehards from the fair-weather fisherman, and the rewards can be tremendous. As Thanksgiving rolls around, the winter-run fish start to make their migration upstream and will settle into the slower, winter haunts, where we like to target them with smaller nymphs and eggs on the dead drift. If you are able to time your trip just after a storm, when the river is on the drop and clearing – you should be prepared for a very productive day of steelhead fishing.
