Bay Back Key.  A small island or correctly called a Key. Located on the east side of the Harbor.
fishin here is ok in the summer not a hot Spot as there is no trough under the mangrove branches.
there is however a trough out in front of the key, that is why this shore line will hold fish.
They can as the tide goes down fall into the trough out in front.

I was fishing this in July the water was high when we got there and we caught fish, so I took pictures and added the page for you.

 a closer look at bay back Key and the bottom around it.

Notice the dark areas around the top and left side of the picture. This means in this area deeper water.
on another thought do you see the dark trough cutting through the sand bar?
on extreme out going tides the fish have a way off the flats or as the water starts coming in it is the first place the fish can get back
up onto the flats. IF you are going to fish this through, do NOT place your boat in line or in the through.
Place your boat off to one side cast at a 45 degree angle in to the trough.
The fish must have an open run way, or they will go to another opening.

Hey Dad found Tarpon here willing to hit top-water lures. Black and Gold was the color he was using.

The Red circle show where the Tarpon were as we first saw them. and this held true until the tide started to stall.
Then the Tarpon started widening out, into the area of the Yellow circles.
 But the most rolls, and breaches were in the red circle. I think as you can see, the water is a bit deeper between the islands.
As the tide flowed through there, I think the Tarpon were ambushing bait fish as The point of the island has a little bit of mangrove trees separate from the main Island. or it is possible, they might have been feeding on the crabs, hiding among the roots.
The Crab may have been the right one as the Tarpon did stay most of the time in the Red circle
 

I tried using the Rapala RIp-Stop lure for snook as it is one of the best Bass lure I have ever thrown. and it worked this little guy and other
went for it, but it broke on the 2nd Snook I hooked just too much money for 2 Snook when many others lures wok as well
and do not break. I will always use it for Freshwater Bass or Peacock, just not for saltwater fish.

This picture shows a mangrove shore line of the key. Two ways to fish this.
Most common way is to cast straight at the shore from the side of the boat as you make your way along the shore line.
A less common but maybe more effective is to anchor up at one end and cast across the shore line. this allows you to cover the shore line
without having your boat in plain view of the fish.

My trolling motor would not work. So I put the boat very close to the mangroves and cast right down the shoreline
getting as close to the branches as possible. That is how I was casting when that MONSTER snook hit.
