I have been out fishing the Squamish River a lot this past two weeks and I have had a lot of fun getting into fly fishing again. Last season (2013) I could see the fly fishing seemed to outperform the other techniques and I figured I had to get into it this again this season.
So far I have been very impressed with the results compared to last season and I think it has been entirely due to the fly fishing techniques. If anything, the conditions seem more challenging this season because the clarity of the river has been variable. Was not bad on Monday but seemed to deteriorate somewhat yesterday with the heat. Played around with lots of things to find out what was optimal and I noticed these things:
a) Flourescent green flies seemed to outperform flourescent pink quite significantly - no idea why.
b) I got more strikes on a sink tip leader than if I tried a regular mono leader with a weighted fly. My detachable sink tip leader seemed to get my fly down to the desired depth without having it snag the bottom.
c) Initially I was casting out and strip retrieving the fly slowly. After some experimentation I found I got best results just letting the fly hang in the current below me without really attempting any kind of strip retrieve ( I would let it hang for 30 seconds, strop a bit, let it hand for 30 etc.) With the poor clarity I believe this gave the fish more opportunity to see the presentation as they were coming up the river.
d) I tried using similar techniques with small dick nites and other little spoons and got no hits on those - it seemed like the fish were very hot on the green flies, tepid on the pink and completely disinterested in anything else.
e) In spite of the difficult conditions I was able to do better this season (2015) than last season (2013).
All I can say is it's been a blast getting into this. I am more of a gear fisherman most of the time but, when the conditions allow, this is hands down the most fun and effective way to catch them.
Got my nephew into it yesterday too and it was a great learning experience for both of us
