Basics of Fly Fishing - Trout Food Series - Mayflies - Part 12
Yesterday, I mentioned a little about when and where the Blue-winged Olive spinner
falls occur, but that was about all I covered. I also said I would cover the methods
and techniques you use to fish the spinner imitations today.  When I read the article
again, I realized I didn't really tell you anything specific about when the spinner falls
occur. As mentioned, the biggest problem is knowing when one is occurring
because they are extremely difficult to see. You can catch them in a surface skim
net but if and when you do, you can rest assured it has already ended. You have to
have a good idea when it is going to occur or you would be waisting a lot of time. I
will get into the techniques tomorrow.

If the sky is light (versus dark) you can often see them by looking up high over your
head. They don't tend to congregate very high like some mayflies. The only ones
you are going to be able to spot are those that fall early in the season from mid
afternoon to early evening when there is still plenty of light. The late season spring
hatches fall near dark or after. As I have said before, they don't hatch heavily on a
bright day but remember, the spinners will be from the hatch that occurred the day
before. If it was cloudy the day before, or light rain, etc., there may have been a
large hatch and if so, you would be seeing a large spinner fall.

Since your odds of seeing any spinners are slim, the best way to key in on them is
to judge it by the current day's hatch. If you witnessed a good hatch, most likely
there will be a spinner fall from the previous day's hatch. If the water is less than 55
degrees start fishing a spinner imitation as soon as the current day's hatch ends.
Most likely it will be about an hour past the warmest part of the day. My guess is this
will be somewhere around 3:00 to 4:00 PM. The spinner fall will occur within a hour
or hour and a half at the absolute most after the current day's hatch. I will get into
how to go about fishing the hatch tomorrow. If the water is warmer than 55 degrees,
I wouldn't suggest you try to fish a spinner imitation until almost dark.

Continued tomorrow.
