David, Here are a few of my favorites for summertime. I learned or made/hybridized these patterns from NorCal flies already in use. I have found that they work everywhere on Steelhead, until the water gets dirty. The first two are used by me when the light is not on the water. The third picture, the copper herniator is my go to "light on the water" fly. I use the purple herniator more than anything else, from sun down until dark.
