When it gets like that, I've had pretty good luck with a 1/4 oz. jig, in bold colors, or a big sand shrimp tail under a bobber. Nothing fancy, but keep the length from bobber to jig/shrimp 1 1/2 to 2 1/2 feet and just fish up next to shore, really no farther out than you can spit. Never assume a snag when the bobber goes down - I've missed plenty that way. You can cover alot of area that others miss if they are casting out where the normal holding water is.
