It is going to be cloudy and cooler on Monday (Oct 27th, 14). I'll be out there with my tiny collection. BWO time is the best fun of the year when it works. When it's on. But it isn't always.
All this (consarned) warm bright sunny weather at BWO time (that we've had for months now) does bring up another interesting thread. The best fishing always seems to come during overcast or even stormy weather--at any time of year. The corollary is slow fishing when it's bright warm and sunny. All of which matters most in Fall for some reason. We've all had good fishing on sunny days in summer, at one time or another. But good fishing when it's bright seldom happens from mid August through to Winter. In the late season if it's sunny the fishing is almost always slow. Certainly slower than it would be if it was cloudy.
For fly fishing anyway. The odd thing is spin fishing success on bright sunny days. Not well skilled and casual spin fishermen who drift along haphazardly in canoes or rafts often do well on sunny days, when they carelessly troll a heavy spoon or spinning lure into deep water in the middle of the river. I've seen it happen many times. Too many times to deny. All of which has to say something significant.
In the late season when the flows are at their lowest and clearest the fish move off the banks and hide at the bottom of deep fast runs in the middle of the river, at least on bugless days when the intense Rocky Mountain sun is at its brightest. I own several spinning rods but never use them. Despite that observed success.
If there is a fly fishing analog it might have something to do with sinking lines and heavy flies. Fished in the middle of the river instead of pecking away at the banks. At least until the sun goes away and those wonderful little bugs start to hatch--when the fish move back out to the edges of the river again.
