Callibaetis have been coming off and a few anglers have been into rainbows eating duns off the surface. That's the goal! Be there when the heads are on the surface eating mayflies. In the coming weeks, look for fish eating carpenter ants off the surface. Definitely have a couple Ant patterns in your fly box. Fishing has been fair at times, awesome by some reports. This reservoir is really, really low. Launching a boat might be difficult.
