If you're trying to cast across conflicting currents, like you have over
there, it's always better if you can, to wade as close as you can to get as
close to the current that you're fishing into. I could cast all the way
across to that slower current, below that island, but I'm going to have an
awful time. My line's going to be twirling all over the place and I'm never
going to be able to keep control of my fly.
Maybe you can't cross the river. We have other things in our bag of tricks.
With a longer fly rod, you can keep your rod high, and try to keep most of
the fly line off the conflicting currents.
When casting across currents like I did up here behind this rock, it's
always a good idea to keep that rod tip high because the current in the
center of the river would have dragged my fly right out of there too
If that doesn't work, you still got other options. Every piece of water is
like a fingerprint, with unique current lanes, and sometimes you have to
try a number of different angles and presentations to get what we call a
dead drift, or drag-free drift. Believe it or not, we have still not
exhausted our bag of tricks.
