Flow has remained consistent for several days ( 13800 cfs at Irwin, 14500 cfs at Heise, 9580 cfs at Lorenzo ). Normal flow at Irwin for this date is about 8700 cfs. Palisades Reservoir is at 39% of capacity and not filling as fast as outflow. Mutant golden stone flies are out, and that decides using their life cycle patterns for early in the day, Hopper-dropper patterns remain effective, while caddis fly life cycle patterns work best later in the day
