In dirty-water Steelhead fishing, the angler needs to take advantage of as many variables as possible to get the attention of lethargic bottom-oriented fish. The most neglected factor is the use of sound/vibration. I’ve found that one of the most effective flies in this category is one tied with a muddler/flared deer hair head. Because I love Spey flies, I tie a Sonar Spey consisting of a muddler head with a Spey fly body. She ain’t pretty but the vibration the muddler head emits makes it easier for the Steelhead to zone in on the fly in dirty water. Keep the head small and use bucktail rather than the traditional body hair. This allows the fly to sink instead of being buoyant.
