It's not the first time I've used this technique, but for the past month I've used it extensively on the Delaware River. I was standing above some riffles,
talking on the phone, and a stripped bass* grabbed my Clouser. The fishing hadn't been too productive that day, and this was the first fish I caught. In my world, if it works once, it should work again.

I drifted the Clouser back through the riffles again, and quickly caught another striper. A few smallmouth and stripers later, the action slowed down. I walked downstream to the top of the riffles, and noticed little minnows swimming in place like they were possessed! Since fly anglers try to mimick the behavior of insects/etc, I see this as imitating the behavior of the possessed minnows. I've had this happens before, usually walking upstream without retrieving my line, or...talking on the phone (Jr calls a lot to complain about being bored while on duty

).
The weather turned here in the last day: much lower temps and steady showers. The Delaware River water level jumped in 24 hours, and I went fishing for smallmouth. I've been unsuccessful the past couple of outings, but hooked in 5 nice smallies once I found where they were holding. The first was the largest, and I must have fed 70 feet of line out when he whalloped the Clouser. He immediately began jumping, and was quite a brute for its size. I was using the questionable Umpqua 3X leader mentioned in another thread, and thought I'd never get this fish to the net. The current was swift, and my rod was bent more than I've seen in quite a while! Needless to say, I re-tied the Clouser after each smallmouth. Ya' never know.....
