To avoid lining spawning Steelhead, you can also use a vertical presentation. Just put your offering under a float/bobber, and make sure it cannot touch bottom, before you drift through those bedding fish over and over and over and over and over. If they are in a biting mood, you will find out pretty quickly. If they are not, you will also find out pretty quickly. Being able to walk away from non-biting Steelhead you can plainly see is something that can only come with time.
