Having a dedicated spring fly box really helps in both cloudy and high-water conditions. Deer hair patterns specifically for caddis are a must-have, especially if you're bouncing around in boulder-strewn streams and faster runs in spring creeks. The Spring Caddis Emerger pattern, as seen in the photo above, uses Kapok, beaver belly, and  snowshoe rabbit fur combined with coastal deer hair to form a very buoyant fly. Often emerger patterns can be a little tricky in faster water, especially in a spring torrent. So building a better mousetrap for those tricky fish, taking only emergers in the faster current, is a prerequisite during these wet and often windy months. Typically, I exponentially pair down my dressings as the season progresses; this same fly will...
