Dayton, I know the area you are talking about. Its the old "catch the fish around the Surrey hot ditch trick". To answer you question as to how to fish it - I wouldn't. Unless I was cat fishing. And good grief, there are some biggins around there. I'm like you, it seems it would hold a lot of crappie but for some reason I've never had any luck there. We have caught some nice ones in some of the creeks off the James in that area. Gray's, Morris and Gordon creeks. But it seems like the bite is too dependant on the tide. When it shifts, they quit biting. Its my opinion that every body of water is different and one has to adapt to it. It could very well be that I don't know how to adapt to that particular area. I will be watching closely to see how you do.
