I fish alot of carp in the summer on Tenkiller , lots of fun and a real challange . I agree that water clarity is a big issue as carp will seldom move-to or chase their prey far from where they are tailing . On tenkiller I use a black krystal wooley bugger and leading the fish by a few feet I cast past the fish and retrieve untill in front of the fish. From there I'll let the fly drop to the bottom and wait for the tailing carp to swim close to where the fly fell. Start a very slow,steady, crawling retrieve at this point and if you feel any pressure on the line lift your rod . If you hooked up then hang on if not then try again .
