Spinner1,

Assuming they are legal there, I would use a three fly, wet fly cast. A Stewart's (Baillies) black spider as the point fly, a red spider mid and a dun spider on the bob. Casting quartering upstream to let the point and mid flies to sink a bit, allow the flies to dead drift through the entire hole.

Should the spiders fail to produce I would throw caution to the wind and use a Dupont lure.
