Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
Surely I would have been shunned, if not down right banished, by my fellow elitists.
I've seem Walnut Creek go from 34F at 8AM to 42F at 2PM, even when the air temp barely makes it to freezing, if it even makes it that high.
So, I'd wade in there with my 5mm Cabelas neoprenes and bust the as much of ice out as I could by wading through it. Then, I'd go sit on the bank for 10 minutes and work on a cigar while the ice floated away. Then, I'd get up and fish my new ice free pool. I caught a lot of fish this way.
I never broke ice, on a trout stream –but considered it. The trout would be willing, in fact the act of breaking the ice and moving fish a bit probably energized them some.
I would suspect that breaking up the ice by trampling through the stream would energize the fish. Not because they are forced to move around but because the act of disturbing the bottom dislodges more available food into the current.
... big-ass egg fly ...
Dunno where this fits into the match-the-hatch / give em "Food" concept, but anglers not bound by tradition, or education, can come up with some amazing things.
Which got me to thinking; where do we draw the line? ... I know that we differentiate with the term nymphing, but is that a difference in insect form or presentation?
