I could see some of them in the afternoon. It was first time for me to see them, surely they were huge! And there was also a caddis's hatch near the bank.
The amount flowing water was about 1,600cfs.
I found the good one was attacking it, but he missed it. So I change it to elk hair caddis which I tied long time ago.
Then he was hooked! It was not huge but beautiful one(15inches/37cm) .
I caught small one by smaller elk hair caddis and caught smallest one by BH caddis pupa as a dropper.
Although I had to leave around five o'clock PM, I had a good time there.
