FF02,

It really depends on the river. Generally speaking, if one can write generally about something as intricately specific as steelhead fly fishing, larger rivers, such as the Skagit, Sauk, Sky, the Hoh and others, fish the swing effectively and more efficiently than nymphing. The swing covers large and broad holding water much faster than can be done by nymphing. Nymphing excels where the holding water is a narrow slot, and especially so if it is also relatively deeper and swifter than the surrounding water.

That water that doesn't fish the swing well used to be called "conservation drifts."

DD,

OC adults are usually more active in the evening, making fishing until "fish dark" very productive. Not to say OC aren't out and about in the morning, but among bugs, OC aren't "morning people." And when conditions are right, steelhead really like 'em.
