Anglers are catching big rainbows! The Big Fish Challenge over the weekend proved that there are a couple decent-sized 20-inch (and larger) fish hanging around. Be aware of the Mother's Day caddis hatch. Blue-winged olives are hatching, so try sizes 18-22, especially on overcast days. Mayflies are also making an appearance. Sow bugs will be more readily accepted with higher water flows. Be aware that they are releasing water from Deer Creek, so water levels are up and ranging from 354 cubic feet per second (cfs) below Deer Creek, to 82 cfs near Harbor Drive.
