Never mind that there are few fish in the river right now. And the water is high. Things can change in a hurry. Here is a conglomeration of winter Steelhead fishing tips in all types of water from Hazlett, Crandall, Bailey et al.
First off, this is a great time of year to work on your air mend.
Here is a great tutorial by Joh Hazlett. The only thing I would add would be to fish this run left handed if you are so inclined. If your fishing the inside seem and casting short its a great opportunity to develop your left hand. Long run, short casts, limited stripping. May as well get some good practice in.
