Hat is a tricky one to figure out right now, but rest assured the fish are there and they are eating insects! Tricos in the morning on the flats are a staple. Look for fish rising regularly just off of seams and on the edges of the aquatic plant mats. Later they will be eating midges or BWO nymphs. Look for Callibaetis Spinners and then the duns. On the Powerhouse 2 Riffle, the Caddis hatch continues to intensify, Glossosoma and Hydrospyche, swinging a Soft Hackle, Bird's Nest or Poopah will get grabs towards dark. Also #16 - 18 Dark Missing Links, and the Lower Sac LaFontaine will work well. Down towards the fish barrier above Lake Britton the Yellow Sallies are coming off in abundance and the Caddis towards dark are blowing up. The warm weather will really spark the Caddis hatches this weekend.
Quick update: It looks like the turbidity went off the charts overnight. Hopefully it is one and done this year......
