The mulberries are ripe along the mid-Columbia. As the berries drop, big carp slurp berries from the surface, leading to exciting fishing for big fish with dry flies.
Mulberries look a lot like blackberries, but a little smaller, and a bit more elongated. They are very sweet, and taste like figs. The cool thing is that they float, so it's a unique opportunity to sight fish for carp with a dry fly. I imitate them with tightly clipped black deer hair on a 2x heavy #8 scud hook.
