fly fishing using normal rod and spinning reel?

[DiehardFishingMan]

I don't know if anyone tried this way before

Last week when I was fishing at Travers reservior, I noticed there were a lof of fish feeding the insects that floating on the water surface just before sunset. I only had my normal rod and spinning reel and no way to fish those fishes.

So could anyone shed some light on how to fish for fishs that float on top of lake water?

I don't have fly rod and boat and can only fishing from the Lakeshore.

Any help would be appreciated
