Couple weeks ago I fished a similar situation in a different state. It was one of the rare occasions I fished off a boat and also that type of cover. Some trees/branches were clearly visible and some were submerged.
I ran a spinnerbait and swimjig on the outsides with no luck. Finally caught one using a jig.
My friend who fishes there often used a Texas rigged creature bait with 1/4 oz weight pegged. He was dragging it all over the place and was able to catch a few. He also got hung up a lot.
As a bank guy, it was a learning experience for me for sure.
