I have no idea about that area either.
To start, go to the
chart 12226 link and start looking at the contours.
The entire creek looks to be shallow but there could be promising areas that are not shown on maps and charts.

Look for points with current on them that may have some deeper water, drop off, any type of depth change. It does not have to be much.
Work your way out to the mouth of the creek again looking for the same thing.
Look for birds, other boats (don't crowd them)
Remember it can/will look different on the different stages of the ebb and flow tides.
Go out at the lowest tides and see what could be underwater structure that could hold fish on a high tide.
Print of buy the chart and carry it with you as you are exploring.
I like to copy/print different sections of charts because you can really zoom in on areas and print them. Make an overall copy and detailed copies.
Make notes on them. Take photos of the areas at low tides.
Fish typically like to have deep water access next to points, flats, hard bottoms, etc.
Use a couple of known fish catching lures and cast you ass off.
Remember, typically fish feed when there is CURRENT.
Good luck.
