Around the end of March, black stoneflies begin to emerge on rocks in streams. This is also the time that steelhead begin to enter rivers in the spring to make their annual pilgrimage to their natal, headwaters streams. Although most fish won’t be looking up for their food just yet, often they can be teased with a well skated dry fly. Black stone flies will be present through June and even beyond in many places, so keep a few of these patterns in your fly box all season long.
