You can access that area during many different tides. The tides you will have some trouble getting in are the winter low tides around the new and full moons (like now). But that would not be a place I would fish right now. Not many fish go back there during the winter. The reason is most of the fish (not all but the majority) are not spending much time in that shallow water because it is just too cold. Most of the fish are in deeper grass flats or up and in around the estuary areas of the mainland. There are also many fish in the rivers and canals. The area you mentioned will start to produce better catches around the spring or when the bait starts showing up on the grass flats outside of North Anclote Key.
On the north end of Dutchman Key (the island in the dead center of Anclote Key), there is a deeper cut that you can follow in and fish the swash channel close to the island. The cut itself will also hold fish. It is a very good winter trout spot. So right now would be a good time to trout fish there. The chart above shows the exact location with arrows showing you exactly where the deeper cut starts and goes back to. You can actually see the cut in my photo.
Good luck and thank you for sending in your question to The Online Fisherman.
