That time of year you should be able to catch both reds and trout in Dana's cove. That's the cover behind the state park. Wade with an old pair of tennis shoes or get some canvas wading shoes or high tops to get started. Mostly silt, sand, and mud with grass in their. Slide your feet along the bottom to make sure you don't place them on top of sting rays...this is called the stingray shuffle. The trout will be on the edge of the grass toward deeper water and the reds will be up in the shallows in the grass. You can catch them on anything that will catch a bass. If you have any zara spooks or similar walk the dog type baits in any natural ish color or bone, chrome, clown etc.. then that will do.
If you want to catch a flounder in that area look for channels that flow water on the incoming or outgoing tide and bounce a jig head with gulp curly tail grub or something similar along the bottom back to you and feel for that bass thump. There are also flats NE of SeaWolf park that you can wade in thigh deep water for flounder there as well... same bait, same tennis shoes, and same stingray shuffle.
Want to learn more about how to be more effective in catching Trout and Redfish.. then check out the TroutSupport DVD's... don't take my word for them, there's plenty testimonials on the web about what they area and how the support anglers.
