By 5:45 AM on Monday the skys were filled with mating clouds of Tricos. The location of the Trico clouds were in shady protected areas and not as evident in the sunny open spaces. I waited and watched but the fish were not on the bugs until the spinner fall, and were particularly persnickity. Long casts were the rule and this made the hook set difficult. The morning was fun and challenging to say the least. The emergence of the Tricos must have happened at daybreak or before so be there early (5 AM) to catch this stage of the hatch. The spinner fall where I was on the Rush river happened about 8AM and lasted for better than an hour with isolated pockets of feeding fish for long after.
