Great question badboard. When I first started to fish East Harbor, I started fishing in the grassy area thinking the perch would hide in there from those bass. Not true with the perch in the grass. They seem to be in the open water. The terns were diving after the minnows along the rock walls on the outside of the marinas. The terns were also diving in that dredged channel area on the south side of the harbor by Marina Del Isle, and Bass Haven in that area in that deeper channel. I know a couple guys who fish East Harbor and they said they have caught perch all over in there except for the grassy area. Year around too.
